What does glass fire mean?

Fire Glass: How it’s Made Fire glass is put through a special treatment that allows small pebbles to come in direct contact with hot flames without melting. … Because it has been tempered, fire glass won’t melt, soot, or explode. It’s safe to use and does emit any harmful byproducts into the air.

Which type of glass is heat resistant?

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass.
