Description
A type of glass containing at least 5% Boron. Borosilicate glass was developed by German glassmaker Otto Schott in the late 19th century in Jena. Originally know as Jena Glass, Corning Glass Works introduced a similar product as Pyrex in 1915. The most common formulation contains 80% silica, 13% boric oxide, 4% sodium oxide and 2-3 % aluminum oxide. Borosilicate glass is highly resistant to heat and shock. It is used in the manufacture of glassware for labs and homes, electronics, cookware and lighting.
