GlassFest Lights Up Corning

What do you do to celebrate your town’s contributions to the glass industry? If you’re Corning, NY, you throw a four-day party known as GlassFest. GlassFest is in its 7th year and boasts all things glass. GlassFest took place this year from May 26-May 29 and featured hot glass shows, live music, food and fireworks.

GlassFest dedicated to glass arts

There were plenty of glass-blowing demonstrations, and thousands of visitors to watch some of the best glass artisans in the country show off their wares. In addition to glass artisans, visitors found plenty of pottery, jewelry and metalwork. And no street festival would be complete without an 8K run. With clear skies and temperatures in the 90s, the weather was just about perfect. Vendors from around the region commingled with food trucks, wineries, musicians and tourists to celebrate the industry that put Corning on the map.

One of the anchors of the festival is the Corning Glass Museum, which is open from 9:00 AM to 5:00 PM daily. The museum has been in operation since 1951, when it was given as a gift to the people of the United States in honor of the 100th anniversary of the Corning Glass Works. Although the company is now known as Corning, Inc., the museum entertains 10s of thousands of visitors each year. But if you visit, you should know that it’s not the “Look-but-don’t-touch” kind of museum.

Instead, you’ll find plenty of interactive displays in the hands-on exhibits in the Innovation Center. You’ll also see lots of Hot Glass Shows, that both occupy museum space, and travel around the country. The Glass Lab is a traveling workshop for designers who want to experiment with glass. New glass makers can take courses at the museum, and researchers can find many Web-accessible resources through the Rakow Research Library – a library devoted to glass. You’ll also find more than 50,000 pieces of glass on display in the museums galleries, the newest of which boasts more than 26,000 square feet of display space.

Although this year’s GlassFest is already in the books, you can make your plans for next year’s event. (The dates have not yet been finalized.)

Glass strength could be doubled

Glass strength could be doubled

Glass strength could be doubled

If someone asked you to make a list of “strong” materials, glass probably wouldn’t make the cut. We associate glass with breaking and fragility, mainly because we’ve all dropped a glass or two, with inevitable results. But researchers are making some surprising discoveries about glass strength and other qualities that just might change the way we think about glass.

New manufacturing process needed for better glass strength

Recent research conducted at Rice University showed that glass strength could be doubled if the glass production process were tweaked. There are few current applications for glass that couldn’t benefit from a little extra muscle. Stronger glass could mean better (and safer) windows, doors and windshields as well as tougher smartphone and tablet screens.

We think of glass as a solid because we usually encounter it in its solid form, but during production, glass is very much liquid. When glass is in its liquid form, the molecules in it have a random arrangement – the same as any other liquid. When glass solidifies, the molecules “harden” in this same random arrangement, unlike other solids, which usually have a more organized, crystalline pattern. This lack of an organized structure at the molecular level changes the strength of glass and explains why glass shatters and cracks randomly when it breaks. If glass molecules could be ordered when glass changes from a liquid to a solid state, the strength of the glass could be significantly improved.

Changing the way glass molecules behave actually requires more than a “tweak” to the glassmaking process. Today, most plate glass is made using the “float” method, which involves “floating” molten glass onto a bed of molten tin. By allowing the molten glass to cool slightly, the glass can be worked into specific thicknesses. Once the glass has achieved the desired thickness, it cools into the hardened glass we’re familiar with.

That approach cannot be used to line up the glass molecules into the crystalline structure needed for additional strength. A completely different process, more like the one used to deposit film layers on reflective glass, could theoretically be used to improve glass strength. Ultimately, all glass is breakable under the right conditions, but stronger glass could have a significant impact on the use of glass in architecture, electronics, automobiles and decorating.

Glass plays an important role in energy efficiency

Glass plays a big role in energy efficiency

Glass plays a big role in energy efficiency

In yesterday’s post, we looked at energy efficiency and glass, and how technological advances in glass have given commercial interiors the edge in reducing energy consumption. Today’s post looks at the most recent energy efficiency developments in glass, and how modern coatings like Glassprimer™ glass paint can help conserve energy and improve comfort.

Glassprimer™ glass paint contributes to energy efficiency

In the late 1980s and early 1990’s, new research was aimed at developing dynamic glass – glass that could automatically change tint based on conditions, reduce heat build-up and reduce glare while still providing a high degree of light-transmission. Comfort and convenience were the primary drivers of glass technologies, even though a clear benefit was a reduction in energy consumption. By the mid-1990s, sales of low-e glass hadn’t changed much; if anything, they declined slightly.

Today, energy efficiency is a greater concern, and while low-e glass doesn’t dominate the residential market, more than half of commercial windows are low-e. The need for a significant amount of natural lighting in commercial spaces, combined with mandates to reduce energy consumption drive the commercial low-e market. Low-e glass is now combined with energy-efficient fabrication techniques and new materials and coatings to create highly efficient, highly functional windows.

Specialized glass coatings, like Glassprimer™ glass paint can also contribute to an increase in energy efficiency. Glassprimer™ glass paint offers exceptional UV-protection, which reduces heat build-up, discourages heat loss and resists peeling and fading over time. Glassprimer™ glass paint is also cost-effective. A single gallon of Glassprimer™ glass paint can cover about 265 square feet of glass. The paint can be used to achieve full coverage or partial coverage, and can be used to create a frosted effect.

The nanotechnology that underlies Glassprimer™ glass paint actually modifies the surface of the glass, creating a permanent bond with the glass. Being able to create this bond is key to delivering superior UV-protection and performance, even under the most challenging conditions.

Glassprimer™ glass paint works with any kind of glass. A window coated with Glassprimer™ glass paint will provide UV protection and reduce the build-up of heat while still preserving light transmission.

Energy efficiency and glass

Energy efficiency and glass

Energy efficiency and glass

Float glass wasn’t mass-produced in the US until the 1800’s, and it didn’t take long for people to figure out that glass isn’t very energy-efficient. The first attempt to make insulated window glass was patented in 1865! The first insulated windows used a double-pane arrangement with an air-gap sealed by thin rope and tar. The approach is still used today, but the materials have changed a lot!

Energy efficiency drives glass improvements

As a building material, glass is very attractive, but ordinary glass doesn’t lend itself to energy efficiency. Because energy is at a premium, energy losses just aren’t acceptable today, so the quest for energy efficiency tends to drive glass technologies.

Following the attempt to create insulated glass in the mid-1800s, there were no major improvements in glass fabrication or glass technology for about 100 years. The earliest glass coatings were developed in the 1960’s. They didn’t gain a whole lot of traction, but glass manufacturers began to develop low-emissivity glass and coatings in the mid-1970s as a reaction to the energy crisis at that time. Initially, much of the glass research and development was being carried out in Europe, but by the late 1970s, more glass research and development was being conducted in the United States.

In addition to research on coatings, new techniques were being developed for applying coatings to glass. By the mid-1980s, the glass industry had settled on the use of silver in creating reflective (low-e) glass. A process known as “sputtering” was used to apply the coatings to the glass surface.

By 1990, about 20% of residential window glass was classified as low-e, even though the primary driver of the technology – the energy crisis of the 1970s – had long since passed. Low-e glass offered the primary benefit of energy efficiency, but the premium glass was developing a following because it made new homes more comfortable.

The key to energy efficiency and glass is to reduce the amount of UV light that successfully penetrates the glass. By reducing UV (and infrared) light penetration, you can control the build-up of heat in a confined space without completely sacrificing transmissible light. Glassprimer™ glass paint is designed to create a permanent bond with all kinds of glass, so no matter what kind of glass you use, Glassprimer™ glass paint can help improve the energy efficiency of glass.

Transporting glass safely over long distances

Transporting glass safely over long distances

Transporting glass safely over long distances

In an earlier post, we looked at methods for transporting glass safely. The post only took into account short-distance transportation – from the glass shop to the worksite, for example. But how does glass get from place to place over long distances, and what challenges can arise when transporting glass?

Transporting glass isn’t for sissies!

Transporting glass over long distances or in bulk requires specialized equipment inside a truck. Breakage is always a major concern, since it can range anywhere from 0.5% to a whopping 40%!. Packaging makes all the difference in the world. Great packaging means few losses. Clever approaches to transporting glass can increase the amount of glass that can be transported in a single load, reduce the losses during transport, and reduce the effort required to move glass from place to place.

One way in which glass fabricators minimize the dangers involved in transporting glass is by regionalizing glass production. By minimizing the distance needed to transport glass to major markets, glass manufacturers can reduce losses and simplify the process of transporting glass. Nearly 50 major glass manufacturers in the US operate about 100 fabricating facilities for plate glass production.

Fortunately, glass production does not require specialized locations, nor is it environmentally unfriendly. Most states have at least one significant glass manufacturing facility, however most glass production facilities specialize in creating a limited range of glass types. Additionally, many production facilities are certified to make glass for major glass companies like Guardian and PPG. A sheet of float glass may be sold under a specific brand name, for example, but it may be created in the same facility as a competitor’s glass.

The biggest issue in transporting glass is not how the glass is transported or how far the glass has to travel, but who is transporting glass. The trucking industry as a whole is facing a huge labor gap. That is, there are far more open jobs than people to fill them. Truck driving takes some specialized training, and transporting glass is a niche specialty, so general carriers tend to avoid transporting glass because they are not set up with the right equipment and personnel to move large volumes of glass.

Fortunately, most individuals don’t need to worry about the long-distance concerns related to transporting glass. If you need to transport glass, or arrange for the transportation of glass over a long distance, you’d be wise to look for a carrier that specializes in transporting plate glass. While transporting glass may be expensive, an experienced glass carrier can make sure your glass gets from Point A to Point B in one piece!

Laminated glass artwork

Laminated glass artwork

Laminated glass artwork

As a building and decorating material, glass is exceptionally versatile, but it can also be used in an artistic capacity. One application that qualifies as both architectural and artistic is laminated glass. Laminated glass consists of at least two panels of glass that are bonded together. Here are a few examples of laminated glass and how (and where) they can be used.

Laminated glass has been around for awhile

Laminated glass is actually a form of safety glass. In this form, two layers of glass are bonded together with a thin vinyl film. If one or both of the glass panels breaks, the film keeps the broken glass contained. Laminated glass has been used in automobile windshields for about 100 years.

As an art form, laminated glass can be combined with a variety of items in the interlayer – the space between the two glass panels. Photographs, ink, fabric, paints and other materials can be bonded between the glass and multiple glass layers can be laminated together to make a unique artistic application.

Artistic laminated glass has been used in Europe for years, in both commercial and residential applications. Laminated glass artwork can combine a number of different techniques and materials, including tinted glass, painted glass, etched glass and sandblasted glass to create a unique yet practical artistic application.

Artistic laminated glass is sometimes called “glass applique.” Although the technique can create a finished product that resembles stained glass, it does not have the black lines that characterize stained glass works. Artistic laminated glass can be used in both commercial and residential settings, as well as both interior and exterior designs.

Some manufacturers have created film laminates that can be applied to the surface of the glass. The films create patterns and colors, but this isn’t really the same thing as laminated glass. True laminated glass bonds glass together and uses the interlayer as a decorative space.

Interior glass trends for 2016

Interior glass trends for 2016

It’s no secret that interior designers for both commercial and residential spaces are increasingly turning to glass as a decorating surface. What’s driving the move toward glass and what can we expect in the coming year?

Interior glass demand is growing

Light, light, light. There’s no denying it; there’s just something irresistible about natural light. With light comes heat, but technological improvements have made it easier and more cost effective to incorporate insulated glass, reflective glass and low-e glass in structures. Designs that use glass to control the amount of light and heat that enter (or leave) the building will continue to dominate the architectural landscape, largely because they support the drive toward optimizing energy efficiency.

Windows aren’t the only use for interior glass. Expect more stairs, walls and even floors. Nothing transmits light like glass, and use of glass throughout the interior of a space can help ensure the maximum distribution of natural light.

More decorative glass. With glass, there’s no need to argue about form or function, because glass will provide both. When natural light isn’t available, translucent glass, low-iron glass and painted or etched glass can help distribute light efficiently in interior design. In addition to windows and window walls, the use of glass as a cladding material will only increase. Color-rich environments, made possible with techniques like tinting and backpainting make glass an entirely versatile material in interior design.

Printed glass. New printing techniques and materials have created new options for decorating glass. UV-curable inks eliminate the need for heat curing, reduce production time and costs, and provide exceptional color depth. Special primers like Glassprimer™ glass surface molecular activator help to ensure that printed inks will enjoy a long lifespan, even in the most demanding commercial environments.

More about specialty glass

The last post discussed two common types of specialty glass – patterned glass and tinted glass. Today, let’s look at two additional types of specialty glass – reflective glass and insulated glass – how they’re made and what they’re used for.

Two less common types of specialty glass

Reflective glass. Reflective glass is a specialty glass that features a reflective, transparent metallic outer layer. The coating reflects solar radiation and reduces the visible transmission (VT) of the glass. This reduces glare and the overall intensity of the transmitted light, but it also reduces the solar heat gain co-efficient (SHGC) of the glass.

In practical terms, this means reflective glass is better at keeping a room cooler during the summer than it is at preventing heat loss through the window during the winter. Reflective glass can make a significant contribution to reducing energy consumption in buildings that receive a lot of solar radiation – such as those in the Southwest.

Reflective glass also has “one-way” transmission properties. The glass is “see-through” in only one direction, so when used on the “skin” of a building, it offers privacy to the people inside, while still allowing light to pass through the glass.

The metallic layer in reflective glass is usually made of silver and a metal-oxide alloy, deposited in multiple separate layers. Reflective glass can be tempered, laminated and double-glazed. It’s important to remember that reflective glass is essentially a mirror and can focus (or intensify) the sunlight that hits it. In one instance, the reflected sunlight from a building in London was strong enough to damage vehicles parked nearby.

Insulated glass. Insulated glass is used in new and replacement residential windows. Insulated windows are made from multiple panes of glass that are bonded together in a single window frame. Usually a small space between panes is filled with ordinary air, or with an insulating gas such as krypton or argon. A triple-pane insulated glass window actually has 6 surfaces and two insulating spaces, which reduces heat losses and makes the window stronger.

Improvements in window technology are critical to achieving gains in the overall energy efficiency of homes and buildings. By combining specialty glass with different materials, glass coatings and construction techniques, engineers can significantly increase the energy efficiency of windows.

Types of specialty glass

Types of specialty glass

The last post discussed types of safety glass, and an earlier post looked at different types of “ordinary” glass. Today, let’s look at different types of specialty glass, how they’re made and what they’re used for.

Two common types of specialty glass and how they’re made

Patterned glass. Patterned glass is sometimes called textured glass, decorative glass, pressed glass or obscured glass. It’s typically translucent and has a physical (raised) pattern on at least one side – sometimes both. Patterned glass often has a pebbled appearance. It’s used to create privacy in spaces where transmitted light is also desirable, so you may see it on private office doors, bathroom doors and windows. You may also see it used for shower enclosures.

Patterned glass is manufactured similarly to float glass, except that one of the rollers that moves the glass during production has a pattern on it. The pattern is pressed into the glass as the glass “floats” by. Patterns are usually created on one side of the glass, but by using two patterned rollers instead of just one, glass manufacturers can create two-sided patterned glass.

Patterned glass can be tempered, laminated or and/or double-glazed. It is also cut and installed just like ordinary plate glass. The pattern on the glass determines the level of obscurity the glass provides. It also comes in a variety of thicknesses and can be tinted.

Tinted (colored) glass. Tinted glass is fairly common, so it seems a little strange to call it a type of specialty glass – but it is! Tinted glass can come in virtually any color, but red, amber, blue, green and gray (or black) are the most common.

Tinted glass can be clear, translucent or opaque and can be combined with other glass manufacturing techniques, like patterning, etching or frosting, and tempering. Tinted glass is manufactured just like ordinary float glass. The coloration comes from different metal oxides that are added to (or found in) the components that are used to make glass. Tinted glass offers some UV-light protection, reduces the transmissibility of visible light, and tends to reduce the buildup of heat from solar radiation.

Glass can also be tinted by bonding a thin-film laminate to the surface of clear glass. Thin film laminates give the window a tinted appearance, but do not offer any UV-protection.

The next post will look at reflective glass and insulating glass – two other types of specialty glass.

Types of safety glass

Types of safety glass

Types of safety glass

In an earlier post, we looked at some common types of glass and how they’re made. In this post, we’ll look at some types of safety glass, and where they can are used.

The most common types of safety glass

Tempered glass. Tempered glass (also known as toughened glass) is the most common type of safety glass. The tempering process balances the compression of the outer surface with tension on the inner surfaces of the glass. This improves the strength and impact resistance of the glass. Glass can be tempered by a carefully controlled heating and cooling process, or by a chemical process. It also changes the way the glass responds to a catastrophic impact. Tempered glass breaks into cubes, rather than shattering into shards, the way ordinary plate and container glasses do. Tempered glass has been used in automotive windows, and in architectural applications like doors and windows. Tempered glass is also used in furniture, “ovenproof” cookware (e.g., Pyrex), shower doors, and other applications where shattered glass would be particularly dangerous. Tempered glass is recommended for use in kitchens that feature backpainted glass. Tempered glass can safely be used in areas where the temperature exceeds 400° F, so it can be used safely around stoves and ovens.

Georgian wired. Georgian wired is another type of safety glass that incorporates a thin-gauge wire mesh. The wire mesh used in Georgian wired glass may be as small as ½” or as large as ¾”. Usually, the glass is ¼” thick, and is fire-rated for 45 minutes. Georgian wired glass is not classified as a “barrier to heat,” but it is intended for openings (including windows and doors) that do not require an impact safety rating. The advantage of Georgian wired glass is that if the glass is shattered, the wire will hold the glass in place. The wire mesh does reduce the transmission of visible light through the glass by about 25%, so that may be a consideration for areas where maximum light transmission is desired or required. Other forms of safety glass may offer better impact protection, heat resistance or fire ratings.

Laminated glass. Laminated glass, which was initially developed more than 100 years ago, is a layered type of safety glass, and incorporates a vinyl film between the glass layers that holds the glass together in the event the glass is shattered. The film is usually made from ethylene vinyl acetate (EVA) or polyvinyl butyral. Laminated glass is used in windshields, glass doors and windows, buildings where hurricane resistance is required, skylights and in other places where shattered or flying glass would pose a serious danger to people. Laminated glass also has UV-blocking and sound-insulating qualities.

These are the most common types of safety glass. Glassprimer™ glass paint can be used with all types of safety glass.
