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?”

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.

Conditioners

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.
