Glass generally refers to hard, brittle, transparent material, such as those used for windows, many bottles, or eyewear. Many glasses contain silica as their main component and glass former. However, glass science commonly includes only inorganic amorphous solids, while plastics and similar organics are covered by polymer science, biology and further scientific disciplines.
Glass plays an essential role in science and industry. The term glass developed in the late Roman Empire. In the middle is the mark from the glass blower’s pipe. Soda-lime glasses account for about 90 percent of manufactured glass. As well as soda and lime, most common glass has other ingredients added to change its properties. Calumite contains mainly silica, calcium oxide, alumina, magnesium oxide, and traces of iron oxide.
