Differences of glass molding processes
Glass is one of the oldest materials known to mankind. Glass was first produced by hand in Mesopotamia and Egypt in 3,000 BC. At that time, glass was mainly used to make small vessels and jewelry. Glass is a material made of quartz sand, limestone and soda with a certain technology by mixing them together. The types of glass differ in the methods of production and the elements added to the basic materials during the manufacturing process. Each epoch and culture had developed its own method and so, over time, the most diverse types of glass were created.
