Glass Furnace Closes in Portland

Glass Furnace Closes in Portland

Uroboros Glass, a glass furnace in Portland, has announced that it will close its doors next year. The closure is due, in part, to the company’s inability to meet a host of new regulations by different government agencies. The company cited environmental, safety and seismic regulations that it said eliminated the company’s long-term viability.

Uroboros Glass one of two Portland furnaces

Uroboros Glass is one of two glass furnaces in Portland at the center of an environmental debate about the safety of its emissions. Uroboros Glass and Bullseye Glass both came under fire after state and federal regulators determined that the companies were the sources of elevated levels of toxic heavy metals in and around their plants.

Bullseye Glass recently resumed full production at its furnace after an expensive filtration system was installed. The filtration system is designed to reduce emissions of heavy metals like arsenic, cadmium, chromium and lead – all of which are used in making stained glass. Following resumption of its full production schedule, Bullseye again is receiving scrutiny from federal and state regulators for unusually high levels of selenium in the air around the furnace.

The new filtration system at Bullseye Glass is known as a baghouse filter. The filtration system costs about $500,000 and Bullseye installed three baghouses, which use a number of strategies to collect particulate emissions. Baghouse filters can have a collection efficiency of as much as 99.9%. Because heating is part of the filtration process, the filtered air can be returned to the production facility to provide supplemental heat, if desired.

Initially, the glass furnaces thought they were exempt from state and federal emissions regulations, largely because state regulators assumed that the glass furnaces operated on a “batch” basis. In reality, the furnaces operated non-stop for long periods to meet consumer demands for stained glass.

Uroboros Glass has not yet named a closure date, but indicated on its Facebook page that the closure would take place in early 2017.

Painted glass is emerging as a potential replacement for stained glass. Painted glass often produces a greater range of colors than stained glass does. Glassprimer™ glass paint is designed to bond permanently to glass surfaces without additional heat curing. Once cured, Glassprimer™ glass paint will not chip, fade or peel, and provides exceptional UV resistance.

Spontaneous glass breakage confounds

Spontaneous glass breakage confounds

Spontaneous glass breakage confounds

If you ask industry experts, one of the most confounding things about glass is the phenomenon of spontaneous breakage. As the name suggests, glass shatters without any apparent cause. Doors, windows and other large sheets of glass seemingly burst. So what causes spontaneous glass breakage? Can it be predicted? More importantly, can it be prevented?

Many different causes of spontaneous glass breakage have been identified, and many of them are not as mysterious as they initially appear. Seemingly minor damage along the edge of a glass panel may cause glass to break without warning. Glass can also be damaged at the time of installation. The damage may not be readily apparent, but this kind of damage can come back to haunt an unaware property owner!

Sometimes the seeds of destruction are sown much earlier – at the moment the glass is created. Inclusions in the raw materials can cause the glass to develop weak spots. Under the right atmospheric conditions, or during normal operation, the inclusions can cause the glass to shatter.

One such inclusion is nickel sulfide. If nickel sulfide, which can be found in the raw materials used to produce glass, is present in the glass mixture, it can pool in the center of the pane when the glass forms and cools. These nickel sulfide “stones” are often imperceptible, and can wreak havoc long after the glass has cooled. Once the glass is installed, temperature fluctuations can change the size of the nickel sulfide deposit, and can flex the glass, which leads to sudden, spontaneous glass breakage. It’s important to note that nickel sulfide causes spontaneous breakage only in tempered glass. Untempered (annealed or heat strengthened) glass does not experience this phenomenon, although it also can break spontaneously for other reasons.

Most glass manufacturers try to eliminate nickel sulfide from their raw materials. In doing so, they reduce the likelihood that tempered versions of their glass will be manufactured with this fatal flaw. In addition, manufacturers sometimes stress the glass panels with heat in an attempt to identify (and destroy) suspect panels before they can be shipped to the end user.

Most often, the cause of spontaneous glass breakage can be traced to production-level flaws, glazing or installation damage, or significant temperature variations that affect the glass once it has been installed in its permanent location.

Because there are so many different causes of spontaneous glass failure, it’s unlikely that they can all be eliminated. Inclusions are often microscopic, and aren’t visible with the naked eye. Testing the finished panels can often help identify flaws, to ensure they aren’t installed. Other approaches, including heat strengthening and laminating, can help control the result of breakage and limit the possibility of injuries.

Fortunately spontaneous glass breakage is rare. Thanks to safety treatments for glass, the risk of injury is also reduced when spontaneous breakage occurs.

New glass may be stronger than aluminum

/in , /by
New glass may be stronger than aluminum

New glass may be stronger than aluminum

Researchers in Japan have created a new glass formulation that may be stronger than aluminum. The value of this glass is that it doesn’t break when it’s dropped or impacted. Glass makers have known for a long time that adding alumina to a glass mixture could make the resulting product exceptionally strong, but simply adding alumina to glass during production doesn’t yield the desired result.

Instead, adding alumina to the glass creates silicon dioxide crystals at the mixture’s point of contact with its container, which ruins the product. The researchers needed to overcome this production issue in order to create super-strong glass. Since contact with the production equipment was the cause of the problem, the Japanese researchers came up with a way to eliminate the container during production.

The process they came up with suspends the mixture on a cushion of air and mixes it with a laser. The finished product displays the expected characteristics – hardness and transparency. The resulting product is also colorless.

The researchers were able to produce the experimental glass in the laboratory, but their experimental methodology doesn’t easily translate well to a mass production environment. The next step is to modify their experimental production to allow the technique to be used to mass produce glass. Once they overcome that hurdle, we could see truly shatterproof glass in mobile phones, wearable technology and other products. Incidentally, the resulting glass isn’t necessarily limited in size. In theory, the ultra-strong glass could be used in automobiles, building windows and doors.

Glass already comes in a number of formulations that offer a number of different properties, but regardless of the formulation, Glassprimer™ glass paint will bind to them all. Glassprimer™ glass paint is designed to create a permanent bond to the surface of glass. It also makes the same permanent bond to other impervious surfaces, like stone, metal, ceramics and plastic. Glassprimer™ glass paint can also be tinted to match the paint palette of virtually any major paint manufacturer.

Iconic Glass Structures – The Shard

Iconic Glass Structures – The Shard

The Shard is a 95-story retail, office and residential building in Southwark, London. The glass pyramidal tower is considered part of the London Bridge Quarter development. It is the tallest building in the United Kingdom and the fourth-tallest building in Europe. Construction on the building began in 2009 and was completed in 2012.

Although the building has 95 stories, only 72 have usable floor space. In addition, the building features a publicly accessible, open-air observation deck on the 72nd floor. The Shard replaced Southwark Towers, a 24-story office development that was built in 1975. The building is partially owned by the State of Qatar.

The building was proposed and designed by Italian architect Renzo Piano in 1998. By 2003, the building’s design had been finalized and approved for construction. The developer secured financing and bought out the existing leases from the occupants of Southwark Towers. Southwark Towers was demolished and construction on The Shard began in 2009.

While the site was being secured and prepared for construction, concerns arose about the project’s financing. Originally, the cost of the project had been estimated to be £350 million, but in the interim, projected costs had increased to £435 million. The project developer, Sellar Properties, secured additional funding from Qatari investors.

The glass building was designed to appear as though it were emerging from the River Thames. The designer said he was inspired by the church steeple in the historic London area where the construction was proposed. When the building design was initially revealed, it was roundly criticized. The English Heritage Trust claimed that the building would be “a shard of glass through the heart of historic London.” The imagery stuck and gave the building its popular name.

The building is energy efficient, and contains its own natural-gas fired electric power plant. Waste heat from the plant is used to supply domestic hot water for the building. The Shard was one of the first buildings built post-9/11, and features a number of structural design modifications designed to help the building retain stability under an attack.

The Shard is covered by 11,000 angled glass panels that combined cover 56,000 square feet of exterior surface area.

Corning puts Gorilla Glass in Automobiles

If you have a mobile device, chances are very good that it uses Corning’s Gorilla Glass to protect its touch screen. Gorilla Glass has been used in more than 4.5 billion mobile devices. Corning has just announced that Gorilla Glass is making its debut in the ultimate mobile device: the automobile.

Gorilla Glass featured in center consoles

You might think that break-resistant glass is an obvious choice for a car, but you won’t find Gorilla Glass in windshields anytime soon. Gorilla Glass will be incorporated into a full glass center console developed by Faurecia and on display at the Paris Motor Show this month.

According to Faurecia, the Gorilla Glass will be used in a cold-formed touchscreen cover for the company’s “Smart Pebbles” configurable console application. The console contains the vehicle’s entire instrument display cluster, as well as an airflow management system. The console application supports autonomous driving, as well as conventional driving, and is fully touch controllable.

When a vehicle is in autonomous driving mode, the system activates a second screen and produces a tabletop which the occupants can use for storage, work, eating or leisure activities.

The glass cover is 3-dimensional, and can be formed in any shape. The touchscreens use AMOLED lighting, and can interface with other mobile devices. The Smart Pebbles system also includes seating controls and amenities designed to improve the comfort of the cabin.

Corning and Faurecia believe that consumers want their vehicle displays to function similarly to current smart phones, and have designed the Smart Pebbles applications to duplicate the smart phone experience. Cold-formed glass is less expensive to manufacture, a consideration that will be attractive to automotive manufacturers. The improved visibility of the AMOLED displays under the Gorilla Glass also means that the displays can be flush mounted; they will not require additional dimensional shading to maintain visibility, even in direct sunlight.

Philly Office Building To Use Photochromic Glass

Philly Office Building To Use Photochromic Glass

A new office building planned in Philadelphia will use photochromic glass. The windows will tint automatically to reduce glare and solar heat gain. The building, known as 3.0 University Place, will open in early 2018. The 189,000 square foot building’s windows will have sensors that detect the level of ambient light and tint to reduce glare and heat buildup.

The windows, made by SageGlass, can also tint via remote control, to better suit the preferences of building occupants. Photochromic glass won’t be the building’s only energy-saving trick. The structure will feature solar panels on the roof and a rainwater collection and purification system for water use inside the building. The building will be the third in a planned development of six buildings that all feature energy-conserving, environmentally friendly operational techniques.

The Steward Partnership, the buildings’ developer, is seeking LEED Platinum certification for 3.0 University Place. Platinum LEED certification According to the developer, the building does not yet have an anchor tenant, but several Fortune 500 companies are in talks to occupy the space when it is complete.

Energy conservation is driving building design. Glass plays a major role in reducing energy consumption and energy costs. Whether by using photochromic glass, window treatments, energy efficient windows or glass coatings like Glassprimer™ glass paint, in most cases, light control equals heat control, and heat control equals a reduction in energy consumption.

Glassprimer™ glass paint is specially formulated to make a permanent bond with glass. Unlike ordinary paints, Glassprimer™ glass paint will not chip, peel or fade, even in direct sunlight or high humidity. Glassprimer™ bonds with the glass surface by modifying it, so the paint performs year after year, even in demanding conditions.

Glassprimer™ glass paint can also be used for both interior and exterior paint projects, and on a variety of hard surfaces, like stone, cement and metal, in addition to glass.

Decorating with Glass

Decorating with Glass

Decorating with Glass

When the task is to decorate a room, most people focus on colors, furnishings, textures and flooring. One important element of decorating is light, and the source of most natural light is the window. Glass is an integral part of a decorating scheme, so it’s important to remember it when making a decorating plan.

Include glass in your decorating plan

Windows have two primary purposes – light and ventilation. In some cases, a window is non-operable, so letting in light is its only gig. Light’s visible components are definitely desirable, but light has invisible components that bring in unwanted (or much wanted) heat.

Light and the accompanying heat raise the temperature of a room. That might be desirable in some settings, and highly undesirable in others. With an operable window, you have the option of ventilating with natural air. With inoperable glass, your only option is to turn up the air conditioning.

Letting in light means letting others have a view of your interior space. In most cases, that’s not what you want, so a decorating plan that includes glass will need to take into account the need for privacy.

You can “privatize” your window glass with a wide range of window treatments – including blinds, shades, drapes and shutters. You can also use frosted or coated glass to limit the ability to see out of the window without completely restricting the light that gets in.

Glassprimer™ glass paint offers a frosted effect paint that enables you to “frost” ordinary glass at a fraction of the cost of true frosted glass. Glassprimer™ glass paint creates a permanent bond with the glass surface, so once the paint has cured, it won’t come off.

Glassprimer™ glass paint also offers exceptional UV resistance, which means that it rejects some of the heat-generating light wavelengths that raise the temperature of a room, and bleach out colors in carpets, fabrics and hard surfaces.

Gorilla glass for wearable technology

Gorilla glass for wearable technology

Wearable technology is making a play for a bigger piece of the mobile market share. According to Gartner and other industry analysts, the wearable technology market will grow to $150B or bigger in the next decade. With that much wearable technology around, that means an awful lot of glass. Corning has recently announced its latest version of Gorilla Glass – Gorilla Glass SR+ – designed especially for wearable technology.

Given the rugged and unpredictable environment that the trackers may find themselves in, the use of Gorilla Glass SR+ and other specially formulated glass displays makes sense. Currently, one in five adults in the US own at least one wearable device, and the market is poised for tremendous growth.

Gorilla Glass SR+ is designed specifically for wearable technology. The new formulation is specially scratch resistant and improves visibility for small displays. Currently, Gorilla glass is used to protect more than 1,800 mobile/wearable devices on the market.

Unlike mobile devices – where the danger for the display is in being dropped – glass in wearable devices has to be strong enough to withstand daily wear and the little knocks and abrasions that go along with it. Most wearable technology is oriented toward fitness tracking, or extending or substitute for a mobile phone.

Wearable technology certainly isn’t new, but designers are reformulating technology to manage many things. One could argue that glasses, contact lenses and hearing aids are forms of wearable technology. In fact, they are, but the combination of miniaturized computing power and small packaging opens up new applications.

In addition to “smart watches” and activity trackers, wearable technology could encompass medical monitoring, data synchronization, navigational assistance and even as a way to monitor the alertness of drivers and machine operators. Some companies have already used facial recognition technology to spot fatigue in machine operators, allowing them to intercede before an accident occurs.
The success of the wearable technology market depends heavily on the strength and function of glass.

Glassprimer™ glass paint is a specially formulated paint product that adheres permanently to glass surfaces. Once cured, Glassprimer™ glass paint will not chip, fade or peel, and offers superior UV-resistance in both residential and commercial applications. Glassprimer™ glass paint is suitable for use in both interior and exterior settings. For more information about Glassprimer™ glass paint please visit our website.

Get to know glass fiber reinforced concrete

These GFRC pieces are nearly 7′ tall.

If you’re always on the lookout for interesting decorative materials, get to know glass fiber reinforced concrete. If the word “concrete” immediately makes you worry about weight, you should definitely read on.

Glass fiber reinforced concrete (GFRC) is used to create façade panels, shaped concrete, countertops and other similar surfaces. GFRC can also be used for smaller, free-standing pieces and decorative molding. It can be used in interior and exterior structural and non-structural applications.

Glass fiber reinforced concrete is versatile, strong

Glass fiber reinforced concrete is made of sand, cement, polymers and glass fibers. It sounds a lot like regular old concrete, except that it doesn’t contain any rock aggregate. This lightens up GFRC substantially. It also makes it more amenable to being shaped, flexed, stretched and compressed without breaking or cracking. Glass fiber reinforced concrete is also strong, which makes it desirable in building and decorating applications.

The secret to GFRC’s strength is the glass fibers. The glass fibers give the mixture its tensile strength under load, while the polymers distribute the load evenly.

GFRC can be made by spraying the concrete mixture into forms while long glass fibers are added. This allows GFRC to be cast in place, and eliminates the need for separate transportation and installation. It also allows the concrete to be shaped in virtually any form.

GFRC can also be made by premixing the glass fibers into the concrete-polymer mix. These fibers are shorter and are not as strong as their “sprayed up” counterparts.

A hybrid method of creating GFRC combines the spray and premixed method. Using this approach, a thin facing coat is sprayed into a mold, then a fiber-reinforced mixture is added to the mold. This approach is usually used to make concrete countertops.

Glass fiber reinforced concrete is about 75 years old. It was first developed in Russia in the 1940s, but didn’t gain much traction until the 1970s. The technique has been tweaked a bit, but it’s gained popularity as the price of cement has risen. GFRC can be created for somewhere between $3 and $4 per square foot.

GFRC can be surface treated in a number of ways, including etching, sand blasting, polishing, dyeing and painting. It can also be pigmented during production. You can use Glassprimer™ glass paint on surfaces like GFRC. Glassprimer™ glass paint makes a permanent bond with surfaces like concrete, and offers exceptional UV resistance.

Simple ideas for decorating with glass

Simple ideas for decorating with glass

Decorating in kitchens and baths can be challenging. The space is entirely necessary in a home, but they’re often small, especially in older homes. Their size limits what can be done, so without making major changes to the design of a home, it can be difficult to open up these spaces.

Glass is a versatile decorating material

Glass can play a major role in opening up space in small homes. Glass is an ideal decorating medium because it offers so many benefits. It’s sophisticated, inexpensive, plentiful , cost-effective and safe. It’s easy to clean, care for and replace. It stands up to even the harshest household cleaners. It’s impervious and easily sanitized. In addition, it permits the transmission of natural light and easily opens up the space in a room of any size.

Glass can be used effectively in kitchen surfaces, whether vertical or horizontal. It is easily cut, shaped, mounted, framed and painted. Ordinary paint doesn’t adhere to glass because it is designed to stick to porous surfaces. Glassprimer™ glass paint is specially engineered to bond with glass surfaces by modifying the surface of the glass. Once cured, Glassprimer™ glass paint does not chip, fade or peel, and will stand up to high humidity, significant changes in temperature and exposure to direct sunlight.

Glass can be used effectively as a room divider. Glass transmits natural light, which has an unmatched ability to open spaces up. Being able to see through a divider makes a small room look larger. Glass can be incorporated into doors and walls without sacrificing privacy, largely because you can apply coatings like Glassprimer™ glass paint. Glassprimer™ glass paint can be tinted to match virtually any paint palette. This allows you to incorporate painted glass into any decorating scheme.

Glass can be used effectively to reduce energy consumption when it is used with specialized coatings like Glassprimer™ glass paint. Glassprimer™ glass paint permits the transmission of visible light while rejecting invisible light frequencies that raise interior temperatures and requires additional energy consumption.
