Where did glass come from?
Glass is defined as a solid material in which atoms are distributed randomly at equal distances, making them non-crystalline, fused at a very high temperature and converted to a solid state when cooled. This material is also brittle and transparent. Not any solid crystalline material is a glass, unless if it is in a glass transformation, natural materials are used in the manufacture of glass such as: sand, limestone, soda, feldspar, selenium, chromites, gypsum, and coal.
