borosilicates, plural;
-
A low-melting-point glass made from a mixture of silica and boric oxide (B2O3)
Web Definitions:
- a salt of boric and silicic acids
- Borosilicate glass is a type of glass with the main glass-forming constituents silica and boron oxide. Borosilicate glasses are known for having very low coefficients of thermal expansion (~5 × 10−6 /°C at 20°C), making them resistant to thermal shock, more so than any other common glass.
- A hard glass with a higher melting temperature used in flameworking, especially in larger projects. Its lower COE makes it easier to rework and finished pieces more resistant to thermal shock
- A family of glass compositions in which boron trioxide and silicon dioxide are major components.
