How Much Does Glass Cost? 3 Important Factors

If you’ve ever wondered why your glass order was quoted at a certain number, you are not alone.

“What makes up the cost of my glass?” is one of the most common questions we get here at Swift Glass.

There are a variety of factors that contribute to the price of a glass part — the quantity of the order and the size of your glass piece being the two most obvious factors. Here are three other notable considerations.


irregular shaped glassAdvances in manufacturing technology have led to advances in glass shaping capabilities. Processes like state-of-the-art glass drilling, waterjet cutting, and computer numerical control (CNC) machining can all be applied to glass shaping.

Today, glass parts can have virtually any shape, from standards like squares and circles to highly complex organic, irregular, and geometrical shapes. The more complex the shape of your glass, however, the more advanced technologies required to produce it. The use of advanced machining processes adds to your glass prices.


edge-grindingThere are many different forms of edgework that you could specify for your glass part, and they all have an impact on the price of glass.

The most basic edgework, a simple cut, is required for virtually every glass part as a matter of course, and will have minimal to no impact on the cost of glass.

Cut and swipe, a swipe being a very slight bevel, will increase your glass price modestly. Very complex edge grinding, such as special or custom bevels, could increase the cost of glass considerably.

Strengthening & Tempering

heat strengthened glassStrengthening and tempering procedures — additional steps performed after your parts are cut — increase your glass prices. If your glass parts are going to be used in a challenging environment and face exposure to extreme heat, pressure, stresses, or chemicals, a strengthening processes is likely required.

Chemical strengthening processes are best for glass that will encounter wind load and thermal stress, while thermal tempering is ideal for glass that will be used in high pressure, high heat, and explosive environments.

The Rise of LED Technology in the Lighting Industry

LED lights and lighting systems are becoming increasingly common in the lighting industry.

The rise in the use of LED lights by commercial building owners and managers, and industrial manufacturers is due in part to the federal government’s energy efficiency standards. Updated periodically by the Department of Energy, new efficiency standards in 2012 require lights to use 25% less energy.

More importantly, commercial and manufacturing spaces are also realizing that using LED lighting carries a great number of benefits.

The Benefits of LED

LED Light Bulb on White backgroundLEDs, or light-emitting diodes, use a semiconductor as a light source. In short, voltage applied to the semiconductor prompts electrons to jump from one atom into an electron hole, an atom with a missing electron. This recombination releases energy in the form of visible light photons.

The primary benefit of LED lights is their incredible energy efficiency, using as much as 90% less power than standard bulbs. LED bulbs have vastly greater lifespans than standard bulbs, lasting up to 40 times longer — an average of 50,000 hours as compared to about 1,500 hours for incandescent bulbs.

Related to lifespan is their increased durability — the diode is encased in epoxy resin, making it much sturdier than the thin filaments of incandescent lights. They are resistant to shocks, impacts, and vibrations, so they are much harder to break. Their durability also allows for their use in extremely cold and extremely hot applications.

Popular Applications and Installations

SONY DSCLED lighting and lighting systems are being used in a variety of applications. Household use is increasing, as is commercial and industrial usage. But there are other interesting usages arising, as well.

One of these is in sports arenas. It was long believed to be impossible to light large venues with LED lights, but that has proven to be very false — in 2015, roughly 90% of all large-scale sporting venue operators that installed new lighting systems opted for LED lighting systems. Sports teams across the nation have saved millions of dollars in electricity costs after making the switch.

Another unexpected application for LED lighting has been museums. The University of Oxford’s Pitt Rivers Museum, as an example, switched to LED lighting as part of an effort to reduce its carbon footprint. They’re expected to eliminate 44 tons of carbon from their footprint, not to mention their expected savings up to $64,000, over the next 5 years. As an added bonus, LED lights generate no ultraviolet light at all, protecting the museum’s delicate artifacts from UV damage.

Manufacturing Glass for LED Lighting

Having been manufacturing glass for the lighting industry for more than 80 years, Swift Glass is a nationally recognized expert in lighting glass — including LED lighting glass. We’ve manufactured glass for major LED installers using specialty glass. We can also offer thermal tempering for added strength. These capabilities, and more, make Swift Glass ideal for manufacturing glass applications for LED lighting and lighting systems.

Letter from the President: Why More Manufacturers Are Reshoring

Reshoring manufacturing jobs back to the United States from overseas is a trend we’ve been seeing over the past several years, and one that’s sure to continue into the near future.
According to a recent Boston Consulting Group (BCG) report, the U.S. gained 10,000 reshored manufacturing jobs in 2014, and hundreds of companies will follow suit in the coming years.

OLYMPUS DIGITAL CAMERAReshoring is becoming more popular for manufacturers across the country as they recognize the true cost of working with offshore factories. Long lead times, poor communication, high transportation costs, huge shipping risks, lower product quality, and a closing wage gap abroad are just a few of the many factors pushing us towards a reshoring initiative.

In addition to declining conditions abroad, American technology and productivity are stronger than ever. In just a few years, there will be virtually no benefit or cost savings to keeping our manufacturing operations overseas, and soon we will see more products than ever, “Made in America.”

Some of the most impactful benefits of reshoring include:

Higher Quality Materials

Overseas manufacturing does not always guarantee the same quality standards like ISO, for example, with which domestic manufacturers are expected to comply. As a result, product quality can be lower in comparison.

Competitive Prices

In addition to the recent increased labor cost trend in China, overseas manufacturing naturally requires greater shipping costs. By moving manufacturing back home, we can reduce these shipping costs while maintaining wage expenses.

A Strong Economy

Reshoring creates more jobs at home and invigorates the U.S. economy.

Shorter Lead Times

Housing every step of production under a domestic roof increases agility and autonomy, which in turn cuts down on order lead times. The lengthy hassle of dealing with overseas shipping that can add weeks or even months to a product’s time to market will be avoided.

Here at Swift Glass, we’re proud to support the recent reshoring trend in American manufacturing and the positive impact it has had on our economy. Located in Elmira, New York, Swift Glass has provided industries across the country with glass fabrication services for nearly 100 years — and hope to provide the same level of service and quality for 100 more.

Thank you to all of our customers for their continued support of Swift Glass, and for customers everywhere who are creating more reshoring opportunities.

How Is Glass Involved in 3D Printing?

3D printing, also called additive manufacturing, is rapidly transforming industrial manufacturing as we know it.

Initially used to create models and prototypes, 3D printing is now increasingly being used to construct finished products.

swift-glass-3D-printingIn the near future, this technology will hold the power to manufacture food, cars, implants, and even soft tissue organs.

The 3D printing process uses computer-automated layering of material to create a three-dimensional object. Just about any material available in liquid or powder form can be 3D printed. The industrial robots performing the layering can be programmed with complex shapes and geometries to produce a diverse range of parts with extreme precision and detail.

Where Does Glass Fit In?

During the 3D printing process, the object being created requires a platform on which to rest. Because of the high temperatures experienced during 3D printing, this plate must be made from durable, heat-resistant materials.

Borosilicate – a glass substance constituted of silica and boron oxide – is the material of choice for these applications. An extremely low coefficient of thermal expansion makes borosilicate more resistant to thermal shock than any other common glass. Even when exposed to high temperatures (up to 500°F or 260° C), borosilicate remains durable and clear without losing functionality.

Swift Glass has been a worldwide leader in custom glass fabrication for almost 100 years. In addition to waterjet cutting, glass tempering, polishing, grinding, lapping, and drilling services, we offer a variety of borosilicate and infrared reflecting borosilicate (IRR) glass from major manufacturers such as Corning and Schott.

Manufacturing Strengthened Glass for Extreme Environments

High-intensity industrial processes call for durable equipment that will prove resistant in the face of even the toughest of applications.

Sheets of Factory manufacturing tempered clear float glass panels cut to sizeIf you’re carrying out procedures against harsh or extreme conditions, it’s essential that your application is equipped with the proper glass component. Tempered safety glass in windshields, for example, provides extra security in the event of breakage.

High performance glass is required to withstand a vast range of pressures, elements, and external factors, each of which vary by industry. When operating in high intensity environments susceptible to extraneous factors, it’s important to be aware of common concerns that can arise.

Below are a few common risks associated with extreme industrial climates, along with the glass strengthening solutions that help reduce those risks:

High-Pressure Exposure

One of the most frequently noted stress points for high performance glass, this can manifest itself in marine, architectural, and even aeronautical environments.

Strengthened glass, however, can help prevent or reduce the adverse effects of high pressure. In addition, strengthened glass helps shield your work environment from harm caused by explosions, bullets, and projectile aftermath, each of which may pose a threat to safety and productivity. Safety glass offerings, like tempering, can help to ensure a less devastating effect upon impact than with regular glass.

Extreme Temperatures

Exposure to extreme temperatures can result in potentially adverse effects upon operations. Fortunately, heat-treated glasses can offer dramatically increased protection against hazards like thermal shock. Heat treatment offers glass—a material often susceptible to high temperatures—increased protection against high-temperature breakage.

Harsh Environments

Exposure to intense, abrasive elements or harsh, wet and extreme environments holds the potential to work against high performance glass. For certain extreme or outdoor environments, heat-tempered glass may not be necessary, but it can provide exceptional resistance against thermal stresses and extreme wind pressure. Fully tempered glass, however, can offer unparalleled safety when it comes to ensuring safety break pattern. If operations are under harsh weather conditions, tempered glass ensures your work environment remains both active and safe.

Viscosity, Refractive Index and Other Important Glass Properties Involved in Material Selection

Glass is among the most versatile of materials. Depending on its composition, treatment, and manufacture, it can be customized for high performance in countless applications.

material-properties-chartIn order to get the right fit for your next glass project, remember to consult properties such as the corrosion resistance, thermal properties, viscosity, dielectric properties and refractive index of potential materials. These properties tell a lot about how a material reacts to its environment, which is especially important for your application’s performance.

Sample Material: Borosilicate

When compared to other types of glass, borosilicate has a high corrosion resistance to acid, but a low corrosion resistance to weathering. Its thermal expansion is very low, and its volume resistivity and thermal shock resistance are both high — but not the highest. Its light transmission is excellent.

Pyrex® and Borofloat® are common types of borosilicate, though both Schott and Corning craft a series of variations with increasingly specific properties.

What does all of that mean?

Because of its resistance to high temperatures and chemical corrosion, borosilicate makes an excellent material for the biomedical and research industries. It’s also an ideal material for optical, lighting and industrial applications.

Because this is a glass that demonstrates strength without being the absolute strongest, borosilicate is an affordable material, making it extremely popular in many industries. Of all possible glass materials, it’s the Swift Glass choice for all of our annular edge glass. Its edges can be ground specially to be sealed in a flange for biomedical, research, optical, optoelectronic, photonics and analytical applications.

Other Material Options

For the toughest situations, traditional glass materials may not be enough — no matter how naturally strong. Thermal tempering and chemical strengthening can further prepare glass for high-intensity applications, such as:

  • High Pressure Windows
  • Explosion-Proof Windows
  • Lighting Products
  • Industrial and Residential Doors

The additional safety and dependability offered by tempered glass serves many industries, from automotive to medicine.

What If Your Glass Piece Requires an Irregular Shape?

What happens when you need glass cut into something like the shape to the right?

cloud-glassPrecision glass manufacturers utilize a variety of technologies to craft even the strangest of shapes that require clean edges, precise spheres and smooth surfaces.

The glass mirror piece in the photo to the right is one example. Precision manufacturers like Swift Glass utilize a variety of techniques to achieve difficult configurations like this one.

Before you dismiss your drawing as too difficult, check out some of the capabilities that glass manufacturers are leveraging today:

Waterjet Technology for Precision

The highly pressurized stream of water from a waterjet cutter provides an exceptionally smooth and controllable tool. These cutters can automatically switch from low to high pressure mode in the midst of a single tool path, allowing for specialized cuts at high speeds — even in the most brittle glass.

Our waterjet cutters work with CAD compatible software, integrating drawings seamlessly and efficiently from original concept to final product.

Our tools can cut virtually any shape down to 0.5mm thick, and can handle glass materials up to 9 inches thick. High pressure waterjet cutters create pinpoint accuracy smoothly cutting holes, notches and details without damage or distortion.

Irregular shape water jet cutting works well for quartz, optical glass, fused silica, Borofloat®, Pyrex®, and many other specialty materials.

CNC Machining for Tough Glass Materials

Three- and four-axes diamond tooling technology allows manufacturers to cut the toughest materials, including quartz and high-pressure gauge glass. These glass milling solutions serve a range of industries, from optical and lighting to aerospace and energy.

Glass Drilling for Unique Projects

Many businesses require glass doors, mirrors, or furniture with functional or decorative holes. Glass manufacturers use high precision hole drilling to meet exact dimensions and specifications. Diamond-tipped drill bits have the ability to cut holes perfectly with very close tolerances, for materials up to 1.25 inches thick.

Swift Glass is one of the nation’s leading manufacturers of fabricated glass parts, including reliable cutting solutions for glass shapes of all kinds. With over two decades of experience in custom water jet cutting, we can confidently promise both versatility and precision for even the most intricate projects.
