        At present, the highest temperature resistant glass in China can withstand 1500 ℃ (instant), and the softening temperature of glass is 1800 ℃ It is a kind of glass with high transparency and excellent heat-resistant impact strength.
        This kind of glass has excellent chemical stability. It is a special glass for high-temperature observation ports in chemical, petroleum, electric power, military and other places.
