SCHOTT Robax® Transparent Ceramic Glass
SCHOTT Robax is a transparent ceramic glass that is extremely heat resistant. The combination of good optical transmission (including infrared, which we perceive as heat) and low thermal expansion make Robax an excellent choice for windows in heating devices. Robax also has good UV blocking characteristics. The most common uses are fireplaces, stoves, and other types of heating systems.
