High borosilicate glass is a kind of glass with enhanced fire resistance.

High borosilicate glass is mainly composed of three elements: silicon, boron and oxygen. The boron content is high, which can improve the heat resistance and corrosion resistance of the material. Soda-lime glass is composed of elements such as sodium carbonate, calcium oxide, silicon and oxygen. The higher sodium and calcium content can improve the material's impact resistance and light transmittance.
