When most glass is heated, it expands, when cooled, it contracts. This is known as thermal expansion, and the amount the glass expands or contracts is measured in something called the thermal expansion coefficient. Normal glass has a high thermal expansion coefficient, this means that when normal glass is heated it expands very quickly. When the glass expands rapidly it breaks, this is known as thermal shock or a thermal break . Glass can be made to resist thermal shock or a thermal break by changing its chemical composition, method of manufacture, or both. .
Schott Robax® Heat Resistant Glass
SCHOTT ROBAX® is an extremely heat-resistant, transparent ceramic fireplace glass which can be produced in a variety of shapes and sizes to meet your specific needs. Thanks to its extremely low thermal expansion, neither high temperatures (up to 760°C) nor considerable temperature changes can do harm to SCHOTT ROBAX® glass ceramic panels. ROBAX® ceramic fireplace glass has thus proved a reliable vision window for room heating devices such as fireplaces and stoves for 30 years. Onlookers can enjoy the dancing flames and cozy warmth, are protected from flying sparks, and make optimum use of energy through targeted regulation of ingoing air and flue gas.
