Why Does Glass Change Color Over Time? Springfield Glass Answers

Have you seen some old glass windows up close? You might see black streaks, brown spots, or even rainbow-colored wavy streaks within the glass. What causes this discoloration? Springfield Glass Company explains in today’s blog.

Moisture is the most common cause of window discoloration, particularly for double-pane windows. Lingering moisture can become trapped within the panes (usually due to shoddy workmanship before installation). Moisture then allows mold and mildew to thrive. The usual colors are black or brown, but you might see orange, green, or white streaks depending on the type of mold. We’ve seen all kinds of discoloration with repair or installation projects completed by Springfield Glass Company.

Old Age

Some glass windows are simply old. Due to antiquated manufacturing techniques, you might see wavy streaks of rainbow colors that start from the top of the window and work their way down.

Another interesting aspect of this phenomenon is that some types of antique glass are very slightly liquid. They feel solid. But the internal structure of some antique glass maintains a slightly liquid form, which is why the rainbow streaks look wavy and gravitate downward. Of course, this very slight liquidity is hardly noticeable as it takes several decades for these rainbow streaks to form.


There are three ways to solve discoloration on windows. 

Cleaning. Some discoloration may go away when you clean the window, but that’s only discoloration on the outside of the pane. Internal discoloration requires a different remedy.

Tinted film. Tinted film turns your window a different color, and it’s good for improved thermal control of your building. However, tinted film only masks the true problem of moisture or old age.

Window replacement. The only way to truly solve internal discoloration of windows is through replacement. Springfield Glass Company can replace your old windows with new ones that are modern and will last a lifetime.

Why Do Sudden Temperature Changes Crack Glass? Springfield Glass Explains

Perhaps you’ve experienced this scenario before. One of your drinking glasses cracked suddenly after heating up a cold beverage in the microwave. Or perhaps you see a crack in one of your windows that starts at the edge and works its way towards the middle, and it wasn’t there the day before.

We call this thermal fracturing. Today’s blog from Springfield Glass Company explains why sudden temperature changes cause cracks in glass.

Underlying Cause of Thermal Fracturing

A temperature differential represents the main cause of thermal fracturing. Warmed areas expand or cold areas contract in the glass structure. Stresses develop because one area of the glass vibrates (at the molecular level) at a different rate compared to adjacent sections due to differences in temperature.

Situations That Lead to Thermal Fracturing

Springfield Glass Company has seen all kinds of cracked glass over the years. Some typical situations that lead to thermal fracturing include:

  • Hot and cold liquids in a glass cup
  • Solar heating on windows when the middle of the window gets hot but the edges are cool
  • Space heaters near windows or glass objects
  • Fire, either from fireplaces or uncontrolled fires

Where You Might See Cracked Glass

For solar heating on windows, you’ll probably see cracked glass on the edge of the window near the frame. The crack may expand inward towards the middle. Springfield Glass Company can help with a cracked window in your home!

Glassware and porcelain objects, such as a mug or plate, may crack suddenly due to stress caused by the microwave or boiling liquids suddenly poured into a cold glass or on a cold plate.

Placing a cold glass object on or near a space heater or fireplace might lead to cracking.

Preventing Cracked Glass

Cracked glass usually happens when there is a defect on the edge of the glass. Perhaps the edge of a window wasn’t finished properly. Maybe a well-used glass mug had a slight nick or ding in it.

You can prevent cracked glass in a number of ways:

  1. Install tempered or specialty glass for structural glass objects in your building.
  2. Use safety glass or glass film on windows.
  3. Purchase high-quality glassware for your kitchen.

Tempered or specialty glass is especially important for residential or commercial windows. This type of glass helps reduce radiant heat loss while limiting damage due to thermal fracturing. If your home has traditional glass panes, they may suffer from thermal fracturing during the summer. Our team can help alleviate those concerns.

Differences Between Decorative (Ornamental) and Structural Glass by Springfield Glass Company

Glass creates a beautiful addition to your residential or commercial building. It can also provide structural elements to open up spaces while providing an acoustic barrier. In today’s blog from Springfield Glass Company, we examine the differences between decorative (ornamental) glass and structural glass.

What Is Structural Glass?

Structural glass is used when the glass is taking on some of the weight load of the building around it. It’s a strong kind of glass made to support additional weight. It can be frameless or come with a frame. Structural glass undergoes special manufacturing processes to make it more durable and stable compared to decorative glass. Springfield Glass Company can install all kinds of structural glass for residences and commercial buildings throughout Southwest Missouri.

Where Do You See Structural Glass? 

You’ll find structural glass everywhere. A shower glass door enclosure, conference room glass curtain, and heavy-duty storefront window are all types of structural glass. You might see structural glass as a floor that people walk on or a roof that keeps out the elements. You could also see structural glass as part of a vast array of tinted windows that helps with solar control. Aquariums might have structural glass that holds in the water. The type and strength of structural glass depend on its purpose.

What Is Decorative Glass?

Decorative glass, also known as ornamental glass, is used purely for aesthetic purposes. Decorative glass can be tinted, frosted, shaped, or colored. You’ll find decorative glass in doors, bathrooms, shower stalls, coffee tables, and shelves.

What Are the Differences Between Structural and Decorative Glass?

The key difference between structural and decorative glass comes from the framing. Do you see a frame around the glass? If not, it’s most likely structural glass. Frameless shower doors, building facades, conference room facades, and doors made entirely of glass are structural in nature. They’re sturdy and made to last. 

Structural glass is heavier than decorative glass. As such, the amount of glass you can put on your building depends on the thickness and weight of the glass and how it’s held in place. Laminated or tinted glass may change the dynamics of how much glass a building can hold.

What Is Glass Made Of? Springfield Glass Company Explains

In ancient times, glass came from sand that was superheated. The first glass discovered by humans probably came from volcanoes, where you can find the glass-like obsidian. In today’s blog from Springfield Glass Company, we answer the question, “What is glass made of?”

Related Post: Springfield Glass Discusses the History of Glass

Sand (Silicon Dioxide)

The main ingredient of glass is silicon dioxide, which combines the two most abundant elements found in the Earth’s crust. Oxygen and silicon form more than ¾ of the Earth’s hard outer layer. You’ve probably seen something that’s mostly pure silicon dioxide: sand on the beach or sand in a sandbox. 

Limestone (Calcium Carbonate)

Limestone is another common material found in the Earth’s crust. If you put enough pressure on limestone, it eventually turns into oil. The main mineral found in limestone is calcium carbonate.

Soda Ash (Sodium Carbonate)

Sodium carbonate is a white, powdery substance that looks a lot like baking soda. This mineral is the third major ingredient that goes into glass. It also goes into soaps, detergents, and paper.


Manufacturers might also add conditioners to glass, depending on what they’re trying to do with it. Conditioners might add color, change the texture, or increase the temperature at which glass is formed. Springfield Glass Company might order specialty glass that’s textured a certain way to make beautiful effects.

Lots of Heat

Glass is made at a very high temperature — over 3,000 degrees Fahrenheit! The soda ash reduces the melting point of the silicon dioxide found in sand, making it easier to manufacture. But there’s a problem. Soda ash creates a type of glass that dissolves in water! Limestone prevents that dissolving from happening. The end product is technically called soda-lime-silica glass. It’s the kind of glass you see all around you, and the main type we install at Springfield Glass Company.

5 Modern Kinds of Glass & How We Use Them at Springfield Glass Company

Glass has come a long way, even in the last 100 years. Glassmakers began creating glass in ancient times, thousands of years ago, and now the building material is everywhere from skyscrapers and commercial buildings to homes and showers. Today’s blog from Springfield Glass Company discusses the five modern kinds of glass and how we use them. 

Related Post: Different Types of Window Glass 

1. Safety Glass

Safety glass, also called toughened glass, undergoes a special cooling technique to create a certain effect. When safety glass breaks, it shatters rather than breaking into shards or cracks. The shattered pieces may stay together and form a spiderweb-like object rather than exposing sharp edges that people can be severely cut on. Springfield Glass Company works with safety glass regularly.

2. Float Glass

The manufacturing process behind float glass creates a uniform appearance and level finish that’s strong and durable. Float glass is ideal for large window panes and double glazing. Springfield Glass Company may use float glass in multi-story office buildings to give them a modern appearance.

3. Solar Control Glass

Solar control glass contains tinting that maintains heat at various times of year. In the summer, solar control glass keeps buildings cool while the glass keeps heat inside during winter. Solar control glass may have tinting on it to control what kind of ultraviolet radiation comes through. Springfield Glass Company may install solar control glass in commercial buildings.

4. Laminated Glass

Laminated glass remains intact during and after an impact, such as heavy weight suddenly landing next to it, a rock smashing into it, or even a projectile fired towards it. Bulletproof glass contains multiple layers to reinforce the internal structure to prevent any cracks or disjointed pieces.

5. Patterned Glass

You might see patterned glass as part of a glass shower door that distorts the image on the other side of the glass. Manufacturers use several special processes such as sandblasting, irregular heating, or rolling. Patterned glass serves a decorative purpose, especially if you want to have an effect like water waves, stripes, or textures. You can create traditional shapes, like those from historical eras, or modern patterns that create a contemporary appeal. Patterned glass also creates privacy for bathrooms and conference rooms while allowing light into the room.

Springfield Glass Company prides itself on installing and repairing top-quality glass, whether you want new residential windows, custom glass shower doors, storefront glass, or security glass at your office space. Today’s blog from Springfield Glass Company takes a step back to discuss the history of glass from ancient times to the present day.

How Glass Is Made

First, let’s take a look at how glass is made. The basic manufacturing process hasn’t changed much since humans first made glass thousands of years ago. The raw materials come from sand, which consists of silica, soda ash, and lime. Sand is then heated to extremely high temperatures before it cools. While it cools, glass can be formed into almost any shape or thickness, much as it is today with the manufacturers who work with Springfield Glass Company.

Origins of Glass

Mother Nature was the first creator of glass. Obsidian, a shiny black rock, comes from the extreme heat and rapid cooling of lava after it erupts from volcanoes. Humans began making glass as early at 3600 BC in Mesopotamia, or the modern-day Middle East. The earliest known glass objects were beads, and they dated back to 2000 BC. Beads may have been a byproduct of metalworking. Back then, glass was a luxury item.

Going Mainstream in Ancient Rome

By 1500 BC, glass containers were making headway in Ancient Egypt and Mesopotamia. Glassmaking spread throughout the Mediterranean Sea region. When the Romans rose to power around the time of Christ, glassmaking technology advanced to where glass objects went mainstream. In 100 AD, glass was common enough that it became available to ordinary citizens.

Colored Glass

Ancient Egyptians and Romans made small colored glass objects. Stained glass started going into churches around 400 AD, and it became the major art form for glassmaking for the next 1,000 years. One of the oldest known examples of stained glass is from St. Paul’s Monastery in Jarrow, England. A small circular window there contains hues of yellow, orange, green and blue. Artisans made colored glass by adding minerals, such as copper, cobalt, and even gold (to produce red). 

Artisans took colored glass even further by inlaying jewels, pearls, and stones into decorative glass objects. These highly coveted pieces transformed everyday glass items into symbols of wealth and prestige.

Telescopes & Field Glasses

In the 1500s, glassmakers turned to more scientific pursuits. Military leaders coveted telescope glass due to its ability to create lenses that magnified far-away images. Telescopes and binoculars were sought-after objects because they gave armies and navies an advantage in battle.

Modern Manufacturing Techniques

Crown glass, or clear glass made without lead or iron, gained prominence in the late 1600s as a building material. In 1800, steam-driven polishing machines made crown glass accessible to the masses, and window sizes grew. By the mid-1850s, sheets of glass in Europe were large enough to create windows of almost any size. As modern mass production took hold, glass was seen in more and more homes. Many of today’s manufacturers borrow from those earlier processes.

Safety Glass

Perhaps the most important innovation for glass over the past 150 years was the invention of safety glass in 1903. Frenchman Edouard Benedictus dropped a glass flask that contained cellulose nitrate, or a liquid plastic. When the plastic combined with the glass, he noticed the glass didn’t shatter or break like it normally should have. Today, you can find safety glass everywhere in cars and buildings.

Springfield Glass Company Presents Broken Glass Cleanup Tips

Springfield Glass Company Broken Glass Cleanup

Springfield Glass Company specializes in residential glass, commercial glass, custom glass, and glass repair. When your home features beautiful glass items, sometimes something simply breaks. Perhaps a pet knocks something over, or a baseball crash-lands into the middle of your living room. In today’s blog from Springfield Glass Company, we present broken glass cleanup tips.

Related Post: Tempered Glass Versus Standard Glass: Which Is Better?

1. Protect Yourself

Put on rubber gloves and wear shoes (not open-toed shoes or flip-flops) to protect you from the sharp edges. If anyone in your house got close to the broken glass, like children or pets, check them for any injuries.

2. Start With the Big Shards

Springfield Glass Company wants you to remove as much broken glass as possible. Start with the big shards. Pick up the biggest pieces and place them in either a paper bag or double-layered paper bag. Look for pieces as far away as 15 feet away from the point of breakage. Glass can travel a long way when it breaks, even if you just drop a small glass from a couple of feet above the floor. Check underneath furniture, on the edge of rugs, in dark corners, and on any carpets or rugs. 

3. Vacuum Smaller Fragments

Suck up any remaining glass fragments with the hose attachment of your vacuum. Do not use the main portion of your vacuum, as that can cause pieces to fly out from the agitator or can become caught in the fibers of the agitator. Never use a broom, because glass shards can get stuck in the bristles. These shards can come loose later, which can cause more problems. If you must use a broom, throw it away after you’re done.

4. Pick Up Tiny Pieces

All that’s left now is to get the smaller pieces and any glass dust on your floor. This is when you need to use something that causes glass to stick to it. Springfield Glass Company recommends using half of a potato, a slice of bread, masking tape, or a damp and folded paper towel. These items work particularly well for hard-to-reach areas or a confined space.

Double-check everything as you clean up the glass. Look closely, but never kneel down on the floor where broken glass is located because you can cut your knees. Consider vacuuming a second time after you clean up the glass dust with your sticky substance.

Tempered Glass vs. Standard Glass: Which Is Better?

Glass creates some beautiful effects for residential and commercial buildings both inside and out. One of the most common questions we get at Springfield Glass Company is, “Which is better? Tempered glass or standard glass?” In today’s blog, the tempered glass experts answer that question.

Related Post: Custom Glass Glossary – Common Glass Types

Manufacturing Process

Standard glass and tempered glass look similar at first glance. However, intrinsic qualities from each type are very different. Standard glass cools much quicker during the manufacturing process (called annealing), allowing companies to make more glass in a smaller amount of time. It’s also easier to rework, shape, and color standard glass. 

Tempered glass cools much more slowly when it’s formed. Unfortunately, it cannot be reworked once it’s made because reworking tempered glass creates breaks and cracks. However, the advantages of tempered glass over standard glass outweigh the fact that it cannot be reworked.


The main advantage of tempered glass versus standard glass is the strength. Tempered glass is four to five times stronger than standard glass. Just ¼ inch of tempered glass has the same strength as standard glass at 1 inch thick. The annealing process achieves this increase in strength. Stronger glass is why so many commercial buildings use tempered glass in various design elements.


Tempered glass is much safer than standard glass because tempered glass breaks into smaller, safer pieces. Thousands of smaller pieces don’t sound like a blessing in disguise. However, smaller pieces of glass may prevent major bleeding or the cutting of an artery.

Imagine this scenario: Your coffee table breaks when something heavy accidentally falls on it. Tempered glass shatters it into hundreds or thousands of small pieces, which create only small cuts and nicks on your hand if you touch them. If the glass breaks into larger pieces, you have a harder time handling the pieces and they could slip as you handle them. The razor-sharp edge can easily cut through your skin. Rather than smaller cuts that aren’t deep into your skin, the sharp edge of standard glass leaves a gash in your hand that requires stitches and a trip to the emergency room.

Design Versus Function

Standard glass and tempered glass are about form versus function. Tempered glass, also called safety glass, works well for architectural glass, large interior and exterior elements, shower doors, car windshields, and even cell phone screens. Standard glass is more decorative and attractive. You might find standard glass in stained glass windows, cups, drinking glasses, and decorative mirrors.
