Glass faucets elevate indoor plumbing to an art form. The glass is handcrafted in a range of shapes and patterns for visual effect. Metal components are fused into the glass to deliver one of the necessities of modern life, running water. Glass faucets are about both form and function. Glass faucets have a delicate beauty, but they're stronger than they look. The glass is very thick, allowing the faucets to hold up to heavy use and even abuse. A glass faucet starts with chunks of clear glass. The glass worker loads it into a furnace that's fired to over 1200°. A worker selects black and white billets of glass to add stripes and patterns to the clear glass. He preheats them so the
glass won't shock and fracture when exposed to higher temperatures. With a metal rod, he gathers a clump of the clear glass from the main furnace. Using this glob of glass, he collects the preheated white cylinder. He exposes both to the flames that have been heating the chamber, making the glass more malleable. Using a curved wood tool, he gathers the clear glass at the base and wraps it around the white billet, encapsulating it.
He attaches the other end of the glass to a second metal rod. The glass adheres to it and stretches as he pulls it across the room. The glass is now over 12 m long and pencil thin. It starts to cool and solidify as they set it down. He taps the glass against a piece of metal to break it into 20 cm long pieces called canes. They shape another piece of clear glass by rolling it on a metal table called a marver. The glass worker blows through the metal rod, causing the glass on the end to bubble. It will eventually become the faucet and two handles.
He adds a layer of black molten glass to the bubble. His colleague arranges the striped canes on a grooved iron plate and heats them with a torch. The first craftserson then rolls the hot glass bubble onto the canes and they adhere. Then it's back into the furnace and the white striped canes melt into the black bubble. He rolls the glass across the marver repeatedly. He pinches the canes at the top to close them around the bubble. Another reheat keeps the glass pliable as he continues to form it. He transforms the bubble into a hollow glass tube.
He elongates the tube to get it closer to the desired diameter. Using a pinser-like tool, he forms the end into a round handle shape while his coworker aims a torch at it to keep the glass pliable. He creates a hole for a threaded piece of metal hardware. He applies a bit of molten glass to the metal hardware. He inserts the threaded hardware into the round faucet handle and cuts the handle free from the rest of the glass. Then using a forming tool, he refineses the shape. Next, he preheats a metal mold. This stops the hot glass tube from fracturing as he bends it around the mold to shape it into the faucet.
Once the faucet has taken its final shape, it's ready to go into the annealing oven. It bakes the glass at a lower temperature and then slowly cools it. This removes stresses and strengthens the glass. Meanwhile, using very high pressure water with fragments of garnet, they cut trim rings from steel as well as a display plate for the showroom. To install the glass faucet on the display plate, the worker threads a nut to the faucet valve. This showroom display will simulate the look of the faucet in the washroom.
He installs the trim rings at the base of the handles and then assembles them to the display plate. Using the hardware that's been fused to the inside of the glass, he wipes off fingerprints and any smudges. And this glass faucet is ready to make a statement in the washroom. 3 days in the making, it's something very unique for the sink. The use of glass as an artistic medium dates back to ancient Egypt. Despite the obvious fragility of glass sculptures, this art form has an enduring appeal. The transparency of glass often has a ghostlike quality. They're tangible works of art that are skillfully crafted. With this glass sculpture of a horse, the artist's two passions come together.
Art and horsemanship. The artist takes inspiration from her horse, observing the swell of his muscles as he romps in order to create the same sense of movement and glass. She then draws a series of sketches of the horse in different stances. These sketches are an artistic study. They help her work out the sculptures form before actually creating one. She cleans solid glass rods to prepare them for sculpting. This is boro silicut glass which is more resistant to thermal shock than other kinds of glass.
She brings the glass into the flame of a torch to soften it. Once softened, she can fuse two of the rods together. Then using tweezers and flat knifeike tools, she sculpts the glass into the shape of the horse's hips and legs, she works quickly so the glass doesn't have a chance to cool and fracture. She adds a smaller piece of glass and forms it into a tail. She constantly turns the glass as she works it to make sure it looks good from all angles. She melts glass in front of the hips to build up the body and shape the horse's belly, back, and chest. This is intensive and precision work.
The piece must be exposed to a welladjusted flame and constantly moved so it doesn't become too hot and melt too much. She adds glass to the front and sculpts the shoulders and part of the front legs. She removes a little piece of extra glass. She deposits this sizzling unwanted bit in water to cool it down and dispose of it safely. She does more work on the front legs. She'll refine them and form hooves later. But now she bakes the partially sculpted glass horse in a kiln. This is the first annealing which realines molecules to prevent cracking. She forms
the head and mane separately from the body. This is more intricate work. The features are much more detailed. So she uses smaller tools. Once she shaped the eye sockets, she melts little blobs of black glass into them. She sculpts the eyes with a flat knife. She carves creases above them to create an eyelid effect. She adds glass for the ears. Then, using a tool called a masher, she pinches the ears to squeeze them thinner. She heats them again. This process can cause the ears to stick together. So, she cuts them to separate them. She curls the ears using tweezers and tweaks their position on the horse's head.
She melts the base of the head to the body and they become one. She fuses more glass to the back to craft a mane. And after another annealing, she returns to the legs. She softens them with a flame again and adds definition to the fetlock joints. She cuts the tips to create a more level surface. She melts black glass onto the ends of the legs and sculpts it into the shape of hoofs. With a series of tools, she tweaks each hoof until she's satisfied this glass horse will stand the way she wants it to. After another annealing, she shines a
polarized light through the sculpture and examines it for stresses that could compromise its structure. Finding none, this galloping work of glass art is complete. It's been made with great care and caring. Before machine-made plate glass became popular in the 1920s, window glass was blown by artisans. Today, specialty companies still make window glass the traditional way. While machine-made glass is uniformly clear and flat, mouthblown window glass has subtle variations. This German company produces a wide variety of mouthblown sheet glass. It's used to make contemporary wall light panels. It can also be used to make clear or stained glass windows.
The company can make glass sheets in 5,000 different colors and textures. This furnace melts silica sand and other natural materials into glass. The starter begins by inserting the end of a blowpipe into a furnace. He takes a small amount of colorless molten glass out of the furnace and rotates it in a wooden mold. The mold is lined with heavy paper to soften the surface. Then he inserts a metal needle through the blowpipe to create a pathway for air. He returns to the furnace for more molten glass.
The artisans make multiple trips to the furnace, shaping the molten glass in stages so it's easier to handle. This time, the assistant shapes the glass with a large mold. When the shape is set, the assistant prepares it for blowing. He uses a fork tool to push the glass to the top of the pipe. The starter rotates the glass in a larger paper lined mold to round it further. The molten glass cools rapidly once it comes out of the furnace. If the temperature dips below 1,800°, it's no longer workable, so the team must work quickly and reheat the glass repeatedly.
Another assistant lubricates the blowpipe so it will rotate easily on the support stand. The starter hands the glass over to the master glass blower. First, he rotates the blowpipe to straighten and center the drooping glass. Then, he begins turning and blowing into the pipe to gradually inflate the glass. This requires great physical strength as well as tremendous artistic and technical skill. The pipe and glass weigh over 30 lb combined. When the glass starts to cool, the assistant reheats it in a smaller oven.
He passes the pipe back to the glass blower, who then resumes inflating it. This time, he swings it upside down using gravity to help elongate the shape. Next, he will transform the glass balloon into a cylinder. First, he reheats the tip of the glass and weakens it with the hot burner. Then, he reheats the entire glass cylinder. This expands the air inside and forces the weakened tip open. The glass blower taps the opposite side of the hot glass with a cold metal stick. The thermal shock causes a neat stress break. This releases the glass from the blowpipe. Then the assistant slices it lengthwise with a glass cutter
and hands it off to the flattening team. Their job is to transform this cylinder into sheet glass. The flattening master's assistant puts the cylinder into a furnace. It's heated to over 1,500°. The glass softens in about 30 minutes. Then the flattening master reaches into the opposite end of the furnace with a stick and gently opens the cylinder. Next, the flattening master irons the glass sheet with a special wooden tool. The flat sheet goes into the annealing oven for a gradual controlled cool down.
This relieves stress and prevents cracking. The flattening master's assistant removes the glass from the annealing oven and performs a visual inspection. The last step is to cut the edges straight. To make multicolored and textured glass, they add additional ingredients during the melting process. Mouthblown window glass contains natural variations that play with the light and create a subtle glow. A glow that machine-made window glass can't replicate. In glass extractors, solvents capture liquids from solid or semi-olid
materials. For example, oils can be extracted from plants to obtain the essence of their fragrance and flavor. The plant oil can then be bottled for use or incorporated into products. Inside this glass apparatus, extraction happens. Solvent continuously treats a solid material to extract an oil or other component of interest. Making an extractor starts with glass tubing of various lengths and diameters. A glass worker uses this one to form a standard taper joint in one end of the extractor tube. He heats the end to soften it and places a forming tool over
it. In its softened state, the glass conforms to the profile. After controlled heating removes internal stresses, he grinds the joint to the final dimension. The grinding gives the joint a frosted appearance. Another worker widens one end of the main extractor body and forms it into an outer joint. This end will connect to the condenser. The other end connects to the lower extractor body. A worker joins them together. Then using a glass support tool, he inserts an inner siphon tube.
He melts a hole in the lower extractor body and attaches the inner siphon tube to it. He makes another hole in the extractor's main chamber. He then fuses another siphoning tube to the outside of the main extractor body and bends it into a U-shape. He connects the other end of the U to the inner siphon tube and melts the connecting point all the way around to seal the glass. He burns another hole in the lower end of the extractor and installs a tube for solvent overflow. He bends it into a vertical position.
He forms another hole near the top of the main extractor body and connects the overflow tube to it. Moving on to the condenser. Now, a worker shapes the end into a joint that will fit into the top of the extractor. He pumps air into the condenser tube to expand the heated glass within a forming tool. Another member of the team applies an aggregate compound. He inserts it in a spinner that grinds the compound against the glass to refine the profile. He tests the fit of this inner joint against a standard outer one.
Blowing air into one end, he heats the condenser tube in three locations. The air gravitates to the heat and forms bulbs in the part, increasing the surface area inside to improve efficiency. He opens up one end of the condenser tube. Continuing to heat the end, he inserts a reamer tool to widen the opening. He carefully slides the condenser into the outer body using a piece of cardboard. The worker burns a hole in the bottom of the outer body and fuses the end of the condenser to it. He then connects a stem that will eventually carry the condensed solvent to the extraction chamber.
Next, he makes a hole in the top of the condenser and seals a stem to it. This top stem opens the system to the atmosphere to prevent pressure buildup. He also equips the condenser with connectors for cooling fluid hoses. A worker moistens a decal of the company logo and places it on the condenser unit. Then he places the unit into an annealing oven to gradually ramp up the temperature to 140° F and then slowly brings it down. The process both strengthens the glass and bakes the decal into it. heated, evaporated, and then condensed, the solvent in the extractor will separate liquids from solids.
After more than a century of use, it's still a neat trick. Pressed glass originated in 19th century America and England, and it revolutionized glassware. It offered the look of crystal on a budget, adding elegance to a humble meal. It became known as poor man's crystal. Today, this affordable glass still has class. Pressed glass or cut crystal. Invented in the 18th century, pressed glass can still impress company and keep them guessing. Pressed glass ingredients include lime, sodium nitrate, soda ash, silica sand, mineral or chemical colorants, and leftover or rejected glass from the factory.
They melt the ingredients in a furnace heated at over 2900° F. A worker twirls a rod with a ceramic ball on the end into it, and the hot liquid glass clings to it. Then it's ready for transfer to the iron mold. When the mold is partly full, a worker snips the liquid glass with scissors to cut the flow. He places a ring with pegs on the rim to align the mold with a plunger. He lowers the plunger and applies physical pressure to a lever to squeeze the glass into every crevice. This transforms the glass blob into a berry bowl with elaborate impressions on the outside. As it cools, the bowl hardens just enough to be extracted, but it's still quite soft.
Careful to not distort the shape, he transfers the bowl to two bricks. A hose below the bricks pumps air to cool the glass further over a period of 4 hours. The team makes 250 berry bowls. Some of the bowls will be flattened to turn them into dessert plates, while others will be worked into the shape of candy baskets. Once the glass is firmed up enough, the bowls take a couple of trips through the glazer. First upside down and then right side up. A gas flame melts the outer layer of the glass to make it shine both inside and out.
He clamps the bowl onto the end of a rod called a snap and places it into a second smaller furnace briefly. This softens the glass to prepare it for another transformation. Still clamped on the rod, a worker spins the bowl. With a stick of wood, he applies pressure to the upper part to flatten and flare it out. He then draws the piece between two pipes to bend the sides upward. The pressed glass berry ball has now become a candy basket. But baskets need handles. So it's back to the furnace to gather more glass.
He moves the molten glass around on a metal table to roll it longer. He inserts it in a mold that gives the glass a rib pattern. He heats the glass in the furnace one more time. Soft and sticky. The glass handle aderes to the basket. He pulls the handle longer as he twirls the basket and then attaches the other end of the handle to it. The handle is a bit saggy, so before it cools, he improves the shape using an iron roller. As he works the glass, he pulls the handle up and makes it more well-rounded. Unclamp from the gathering rod. Now he smooths the outer surface of the handle and tweaks its shape until satisfied.
Using a torch, he melts the glass a bit where the handle meets the basket to improve the adhesion. Here the pressed glass is heated and then cooled to room temperature over a period of 3 and 1/2 hours. This gradual heating and cooling is critical. It releases stress in the pressed glass to make it less likely to shatter. For generations, molds have been used to mass-produce pressed glass pieces that can look like expensive crystal. With all that practice, they have this down to a fine art. Some works are reproductions of vintage pieces. Others are new patterns.
The appeal is timeless. Thinner than a human hair, ultra thin glass flexes like plastic. It can also have greater electrical sensitivity, making it useful for things like fingerprint scanning on smartphones. Manufacturers have only just begun to explore the potential of this new class of glass. When it comes to sheer flexibility, thin is in. Ultra thin glass bends like a sheet of paper, and a chemical process ensures that it's extremely robust. To make ultra thin glass, manufacturers use standard materials such as lime, sand, soda, and pot ash. They store the ingredients in separate silos until it's time for production. Then inside the factory, a long cable delivers electricity to power a way cart.
As the dry ingredients flow out of the silos and down shoots, the cart moves forward to collect them. It weighs the ingredients until it has the correct amounts for the glass recipe and then closes the lid automatically. A worker measures the secondary, smaller ingredients manually. and adds them to the batch. These ingredients enhance qualities like optical clarity or electrical sensitivity. The cart transfers the batch to a mixer. As it blends everything together, they add bits of broken or waste glass to it for recycling purposes.
Once it's been thoroughly mixed, a lift raises a funnel-shaped container up to the base of the mixer, and the mixer releases the batch into it. A worker hauls the batchladen funnel tank to the next station. There, a crane takes over and lowers the tank onto a feeder system just above a gas and electric furnace. A trap door opens at the funnel's base and the mixture flows into the feeder mechanism. It's a kind of shovel that slowly pushes the mixture into the furnace, which has been fired to a blazing 2732° F.
The shovel continuously adds more ingredients to keep production flowing. Glass production runs 24/7. The melting glass reaches the consistency of honey. The molten glass flows out through a narrow slit and this slit establishes the ultra thin dimensions of the glass. Cooling the glass slowly relieves internal stresses as the glass solidifies. Ultra thin glass can be just 25 microns thick. That's finer than a hair. And it's this thinness that makes it so flexible.
The glass bends to loop down and up across rollers as it journeys forward in a continuous nearly 2-ft wide sheet. And unlike ordinary glass, it doesn't crack. It then travels past tiny cameras and laser sensors that look for defects like bubbles. A computer maps any flaws so they can be avoided when the glass is cut into smaller pieces. A revolving spool rolls up the glass along with a plastic liner, which keeps the glass layers from sticking to one another.
Once 546 yds of thin glass has been wound onto the spool, an automated system cuts the glass and slides the spool partway off the core and onto a rack. The operator gives it a push to complete the transfer and then rolls the rack to the next station. A lab technician slices off a fragment of the glass and inserts it in a micrometer. It gauges the thickness of the specimen and confirms that it's super thin. Another lab worker places a bigger segment of the glass under a cutter. He aligns it correctly and then activates the cutter. It scribes the glass so it can be broken on this line, creating small screens for smartphones and smart watches.
A lab technician examines the glass for scratches under a bright light and confirms that it's undamaged. With that out of the way, it's time to have a little fun with a strip of this ultra thin glass. A worker bends it into a circle and ties it. It's hard to believe this is glass. Later, a chemical treatment will further strengthen the ultra thin glass so that the chance of cracks or breaks will be very thin. Once reserved for palaces and castles, today's chandeliers can be found in even the most modest homes. They function as more than just a light source.
Chandeliers can be the illuminating centerpieces of traditional rooms or give modern rooms an eclectic twist. Either way, a crystal chandelier is always elegant and timeless. This chandelier is quite a showstopper. It stretches more than 3 ft high and wide with 24 elegant arms. It's decorated with clear and red crystal and a gilded hurricane shade over each light. To make the crystal, they melt silica sand in a furnace along with lead, pot ash, and several other ingredients. The materials combine to make crystal heavier and more sparkling than glass. To make each chandelier arm, a crystal blower gathers some molten crystal on the end of his blowpipe, then
shapes the arm with a series of blocks and molds. He makes a channel down the middle for the arm's electrical wiring. Next, two master crystal blowers work together to pull and twist the crystal into the arm's ropelike design. This maneuver requires tremendous expertise. To achieve the correct diameter, these craftsmen must stretch the crystal exactly right. Next, they put it in a chandelier arm mold and snip off the excess on both ends. They blow cold air to solidify the crystal. Another craftsman inspects the chandelier arm, checking the shape, measurements, and channel for the electrical wiring.
Next, a pair of craftsmen make the B-shaped bottom of the chandelier. Using traditional techniques, they place molten crystal in a mold, then place the mold in a press. The crystal chandelier parts are cooled down in an oven. The gradual decrease in temperature slowly releases tension in the crystal. This prevents cracking. Straight out of the furnace, the crystal is 2280°. It continues to be pliable until it reaches about 122°.
It cools rapidly. So, as the craftsman work, they must regularly reheat the crystal in a smaller furnace. The freshly molded crystal tends to have a rough surface, so they use heat from a blowtorrch to smooth it out. These holders support the hurricane shades on the arms. This company produces its signature shade of red crystal by adding 24 karat gold powder to the raw materials in the furnace. The color emerges after the molded piece is reheated in an oven to just over 1,000°. A crystal blower makes the hurricane shades. First, he rolls a starting shape at the end of his blowpipe. Then, with pliers, he narrows and stretches one end to form a neck. By now, the crystal is cooled. So, he reheats it before continuing.
Next, he inserts the crystal into a foot pedal operated mold installed in the floor. He then turns the pipe and blows through it to expand the crystal to the mold shape. Once the hurricane shade has cooled, artisans apply an elaborate 24 karat gold decal. With a paintbrush, they also apply raised gilding and 24 karat gold paste. They heat the shade to fuse the gold to the crystal, then polish the gold with an agot stone. Every part of the crystal chandelier is handmade and the entire chandelier is manually assembled.
However, some of the crystal parts require prep work before assembly. The arms have a light socket at one end wired to a connector at the other. All 24 arms mount to a round tray beneath it. The connectors link to the main wires running down the center of the chandelier. The chandelier's ornate bottom hides it all. The electrical sockets that hold the light bulbs are hidden inside metal sleeves painted white to look like candles.
The gilded hurricane shades go over the candles and sit snugly in the holders. This stunning crystal chandelier casts sparkling light, easily making it the focal point of the room. Weighing in at over 150 lb, this grand chandelier makes a big, bold design statement. In the 1980s, fiberglass doors came on the market. They were well insulated and didn't warp in humid conditions like wood doors. However, they lacked the beauty and texture of real wood. That's now changing with technology that can make fiberglass doors look much more inviting. Fiberglass doors trick the eye and fool visitors. Even up close, they look like real wood. It's an illusion made possible with the help of technology.
A wood grain fiberglass door starts with a real wood door. A computerized cutter carves various panels. An employee sands away any marks left by the cutter. He gently scrapes the wood with the wire brush to expose the grain. He then assembles the panels of the door within a special fixture. Another team member scans the wood door with a laser to confirm its dimensional accuracy. With that confirmation, they're ready to use this wood door to make a fiberglass one.
Next, the worker pours a special silicone mixture onto the wood and leaves it to cure overnight. This step was demonstrated using a smaller section of the door. The silicone picks up all the definition of the wood grain, creating an exact copy of the door. Next, an employee injects a different silicone mixture into a thin gap between the recently created silicone copy and a sheet of steel. The second silicone door copy is thinner, allowing for a better transfer of heat during the next process. They load the door copy, still on the steel sheet, into a chemical deposition chamber. The chemical heats the steel and the silicone, causing a nickel vapor
shell to form. The nickel shell has all the detail of the original wood door. An employee files the edges and adds a protective fiberglass cover over the top of the shell. Workers then lower the nickel shell into a mold base. They remove the protective cover and are ready to use the nickel shell to mold fiberglass door veneers. There are many nickel molds in a variety of door styles at this factory. The fiberglass material now unwinds into a cutting station. A worker slices it into uniform strips.
The fiberglass has a dough-like consistency. At this stage, he places a stack of fiberglass strips on the nickel door mold and lowers a hot press. The press squeezes and melts the fiberglass. It flows into the crevices of the mold. The fiberglass solidifies quickly. An employee removes it from the press and sands the ragged edges. Another member of the team confirms that the width and thickness of the panel are on target. They stain every firstr run fiberglass panel to expose the transferred wood grain. This is a test. If the grain is good, it means there are no defects in
the nickel door mold. It's time to assemble the fiberglass door. Rollers apply glue to external framing wood. The team builds a frame around the fiberglass door skin. They join the wood to plastic casing at the top and bottom of the door. They place a second fiberglass door skin on the top. Then they feed the door through rollers that squeeze it together. This activates the glue for a strong assembly. Next, they load the hollow fiberglass doors into an insulating press. The press closes, holding the doors tightly in place.
A worker fills the hollow doors with polyurethane insulating foam. When foam begins to overflow through the vent holes, the worker knows the doors are full. and runs a finger along the doors to remove any excess foam. Energy efficient and stable, fiberglass doors are a great alternative to wood. With eye-catching wood grain, they're convincing imitations. The first sconces were candle holders attached to the wall by extending brackets to keep the flame a safe distance away. With the invention of electricity, sconces could be mounted flush to walls. This opened up new design possibilities. Among them, art
glass wall sconces. Art glass wall sconces can be used to both decorate and illuminate. Turning on these lights makes a design statement. At this factory, workers craft every sconce by hand. The process starts with scrap glass from a window manufacturer. The craftserson measures the glass and scores it with a cutting wheel. Using special pliers, she applies pressure to fracture the glass along the score line. She manually completes the break. She cuts a large pane and a smaller one. She sets the large one aside and tapes the small one over a detailed sketch of artwork.
She traces the lines of the sketch onto the clear glass using liqufied dark enamel, creating thick lines to mimic the look of lead veins in stained glass. Once the lines dry and harden a bit, she paints the designated colors within them. Each area of the sketch has a letter that corresponds to a particular color of enamel. She centers the painted pane on the clear, larger one to feature the artwork more prominently. Then she transfers the two panes to an electrically fired kiln. It will gradually heat the glass to over 1400° F and then cool it over a period of 10 hours.
This prevents fracturing as the heat fuses the two panes together and bakes the artwork into the glass. The baking also deepens the enamel colors. Next, a mixer blends clay to a pudding-like consistency. An employee pours the clay into plaster molds for the sconce's casing. The clay begins to firm up along the inside walls of the mold. He pours out the clay that's still liquefied. Now a putty-like consistency. He trims the excess at the top. He sets the mold on its side and opens it to reveal the newly shaped sconce casing. It cures overnight.
The next day, the part is still soft but can withstand sanding. The worker thins the rim and smooths the outside. With a sharp knife, he cuts an opening for the art glass pane. First scoring the still fragile clay and then making deeper cuts. He removes the clay cutout. Using a different knife, he now sculpts a chiseled profile along the edges that will eventually frame the art glass pane. He cuts a hole for the light socket and another one to mount the fixture to an electrical junction box. The clay casing now spends 8 hours in a kiln exposed to a temperature of over 1,800° F.
This transforms the clay into a durable glass-like ceramic. He brushes a colored glaze on the outside of the ceramic, leaving the inside white to reflect the light forward. He bakes the ceramic in another kiln for 6 hours, and this fuses the glaze to it. The final finish is glossy and the color is intrinsic to the ceramic. The worker now installs the light socket in one of the holes in the sconce casing and pulls the wiring through the back.
He slides a brass washer over the wires at the back, followed by a second washer that's connected to a ground wire. He secures the washers and the wires to the back of the sconce with a nut. He screws a bulb into the socket. It's now ready for the art glass pane. He pipes adhesive onto the sides of the pane. Picking it up from the unglued ends, he moves the pane into place in the ceramic frame of the sconce window. He clips the paint to the ceramic surround using close pins and leaves the sconce overnight for the adhesive to cure. The next day, the art glass sconce is ready to shine. And after installation, the lighting is on the wall.
Stained glass windows add beauty and light to places of worship. Over time, exposure to the elements and pollution can cause the glass, metal framework, and glazing to deteriorate. Restoration ensures the survival of these sacred works of art for future generations. They are incredible picture windows. Each stained glass panel depicts a religious scene, but it is a fragile art and often only a restoration can ensure its survival.
It starts with a thorough evaluation. An assessor photographs the window. She examines every part as well as measures the panes and connecting lead strips known as canes. She numbers the parts and loads information about their condition into a computer. These canes are in bad shape, so they'll need to completely disassemble the panel and rebuild it. First, they make a rubbing. A member of the team places a large sheet of paper over the back of the window. He rubs a wax crayon over the raised lead strips to transfer the pattern of the panes. After testing the condition of the paint
on the panes, he submerges the glass in a non- acidic cleaning solution and leaves it overnight. This softens the glazing cement between the lead strips so the window can be easily disassembled. He clips off the lead strips. He extracts the glass and cleans off the glazing using a straightedged razor. He gently scrubs off residue with a soft bristled brush and wipes the glass clean. He pieces together the glass panes within the paper pattern. Most of the panes are in good condition and can be preserved. But one is fractured and held together with special conservation tape. They'll need to replace it. A craftserson traces
the outline of the cracked piece onto a new piece of glass. She scores the new glass, giving the outline a wide margin. She snaps the glass along the score line, then cuts the glass along the tracing lines. She compares the pieces to confirm they have the same silhouette. She copies the designs onto the new pane and mixes a matte paint that matches the one on the broken pane. She then shades the designs on the new paint with the matte paint. She dabs it with a brush to create fine crisscrossed lines. Then she switches to a brush with shorter and stiffer bristles. She removes some of the paint following the designs on the pane. This
creates highlights. She fires the glass in a hot kil and then lowers the temperature to anneal it. This process reduces brittleleness. She compares the replicated pane to the broken one. She joins all the stained glass panes using new lead canes. She taps the panes gently with the rubber mallet to fit them snugly into the grooves of the canes. This lead matrix will both unify the numerous panes and create visual interest with bold strokes. Using an electric soldering iron, she melts tin and lead solder where the channeled lead strips intersect.
These solder joints hold the windows lead skeleton together. Another team member applies glazing cement across the front and back of the stained glass panel. The cement provides waterproofing and added strength. He sprinkles calcium carbonate onto the wet cement. It's known as whiting. The whiting soaks up excess oil in the glaze. As he brushes it off, it cleans and polishes the panel. He trims the cement around the lead strips to give them a clean edge.
Finally, he vacuums up the glazing residue. With the restoration complete, he props the stained glass panel against a backlight. It shines like new when illuminated. It's taken about a week to restore this stained glass window. It should last another century or more, providing plenty of opportunities for spiritual reflection. Glass lends a sparkle to any interior. From a bathroom sink to a staircase, architectural glass is both functional and artistic.
The glass can be either handmade or mechanically formed. It's called architectural glass because an architect usually designs its aesthetic features and the objects the glass will be paired with. This company fuses multiple sheets of glass, each about a/4 of an inch thick, to create a finished product of any thickness. For example, this soon tobe kitchen countertop uses five sheets of standard glass. Grabbing one at a time with handled suction cups, they gently place it on a pneumatically operated cutting table. They measure and cut the correct size using a square angle with a diamond tip blade.
Diamonds are the only material that can cut glass. This kiln is a specialized oven for baking glass. A craftsman sprinkles white powder onto the base of the kiln. The powder will leave a texture in the sheet of glass. Next, he sprinkles ground up colored glass across the glass sheet to give the kitchen countertop a unique color scheme. They sandwich the glass with another sheet of glass, repeating this coloring process with each of the remaining layers. Once the last sheet of glass is put in place, they clean the top surface. Now it's time to close the kiln and bake the glass.
Inside the kiln, the five layers fuse into one unit. At another kiln, a stack of glass has been fused together and is ready for the next step. Workers open the kiln and carefully transfer the newly formed glass countertop onto a rolling cart. They take the counter to the polishing machine. With stones and water, the machine grinds down the edges until the layering is no longer visible. The finished glass countertop is strong enough to span over 9 ft without structural support. And because of the heating and cooling process, the glass is now scratch proof and chip resistant. You can even chop food directly on the surface. At a
different kiln, they're making a sink. First, they use a textured glass stamp to press a pattern in the powder. Then, they place three layers of glass over the pattern, carefully aligning the edges. After baking, the three layers are fused into one thick circle of glass. The bottom of the glass has taken on the pattern of the powder, leaving a unique look. This will be the outside surface of the sink. They place the glass over a sink-shaped mold in a different type of kiln. Over several hours, the glass melts into the sink-shaped mold. Once the glass cools, they extract what is now a sink.
They carefully measure and mark where the drain hole goes. Then they drill the hole with a diamond bit. This generates a lot of heat, so they must continuously cool the bit with cold water. Otherwise, the tool could overheat and jam. The glass sink is finished. They use the same technique to produce glass sinks in various colors and shapes. Sometimes these sinks are even integrated with glass countertops. Countless other interior design components can be made from architectural glass.
