Borosilicate glass, made by adding a high proportion of boron oxide to silica as an additional network formation in the glass melt, has a surprising variety of properties that make it ideal for demanding technical applications.
Borosilicate glass is a special type of glass. It is made of silicon dioxide and boron trioxide. It has the advantage that it does not break easily when the temperature changes.
