This amorphous substance is non-crystalline, and it does have the characteristics of a solid despite misconceptions that it is a liquid.
Boron oxide is used to lower the thermal expansion rate of this material. Usually sodium carbonate and calcium carbonate are added in production of this material, making the soda-lime type. Like metals, it can tempered in order to increase its thermal shock resistance and change its (*) break pattern. This amorphous substance is non-crystalline, and it does have the characteristics of a solid despite misconceptions that it is a liquid. It is primarily composed of silica. For 10 points, name this transparent material found in windows.
