Borosilicate glass

High-strength glass, made of silica and boron trioxide

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. The glass has numerous advantages over regular soda–lime glass, including being harder to break when dropped, more resistant to cracking from significant changes in temperature, and having a higher clarity (transparency), which is maintained over a longer period of time. Borosilicate is generally slightly more expensive than soda–lime glass.
