The material

Soda-lime glass is the glass produced in by far the largest quantities of all mass produced glass types. As the name indicates, the main constituents in addition to sand are soda and lime. A typical soda-lime glass contains 71 to 75 percent silicium dioxide (SiO₂), 12 to 16 percent sodium oxide (Na₂O), 10 to 15 percent calcium oxide (CaO) and small quantities of other substances such as dyes. Soda-lime glass is used to make bottles, food jars, simple drinking glasses and flat glass products. Soda-lime glass is light permeable and has a smooth, fine-pored surface, making it easy to clean. Soda-lime glass expands very quickly under the influence of heat so care should always be taken when putting hot water into a soda-lime glass container.
