Pyroceram is made by Corning. Originally made for cookware(Corningware), it is now mostly used for wood stoves and fireplaces. Pyroceramic ceramic glass comes in 5mm (3/16") thickness and 3mm (1/8”) thickness. Although considered clear, it has a very slight amber-colored tint to the ceramic glass. This is due to a chemical called Borrite used in the glass that helps slow down the molecular structure. Slowing down the expansion and contraction of the glass allows the glass to resist extreme temperature variations before failure.
PyroCeram Ceramic glass is a heat-resistant glass-ceramic that can tolerate exceptionally high temperatures. In reality, it is a transparent version of ceramic. Since its creation, manufacturers have extended the use of PyroCeram to commercial ovens, broilers, heat insulators, anti-aircraft missiles, and gaslighting fixtures. PyroCeram is also very effective in blocking UV light waves.
PyroCeram has a high thermal shock resistance. When cold water is poured on hot PyroCeram, it does not crack or shatter the way standard glass would. Having a high thermal shock resistance rating makes PyroCeram an excellent choice for replacement glass in equipment that is exposed to high temperatures or outdoor applications.
PyroCeram can tolerate constant temperatures up to 1,292 degrees Fahrenheit or 1472 F for a limited time.
Ceramic glass does not shatter but will crack and break into large shards/pieces. Pyroceramic glass is NOT safety glass. Pyroceram should only be used in wood-burning, gas, or pellet stoves and fireplaces or lighting fixtures and heaters designed for this type of product.
Neoceram is a low-expansion glass-ceramic with several outstanding features that include high thermal shock resistance, high mechanical strength, and excellent electrical characteristics. Neoceramic ceramic glass comes in 5mm (3/16") thickness and 3mm (1/8”) thickness. Used almost exclusively in wood stoves and fireplace doors, Neoceramic glass will resist breakage in temperatures upwards of 1400 Degrees F.
Neoceramic glass can tolerate constant temperatures up to 1292 degrees Fahrenheit, Neoceram is a great choice for pellet stoves, wood stoves, and fireplaces.
Neoceram is a great choice for wood stoves, pellet stoves, and fireplaces. Many of our customers immediately notice a difference in the quality of this glass when we supply neoceram and replace their existing glass panel, however, this performance is confirmed with years of consistent performance. It has a special coating on both sides which slows down the build-up of soot considerably and can be cleaned using soapy water and a non-abrasive cloth.
Robax Ceramic glass is made by SCHOTT ROBAX. SCHOTT ROBAX glass-ceramic is engineered in Germany and manufactured to demanding German safety and quality standards. Robax ceramic glass comes in 5mm (3/16") thickness and 3mm (1/8”) thickness.
Robax Glass® and NeoCeram Glass® are brand names of heat-resistant ceramic glass that are suitable for use in woodstoves, wood pellet stoves, and coal-burning stoves. They are transparent ceramics that are extremely heat resistant. Tempered glass is not suitable for high-temperature applications.
Standard tempered glass expands when heated and shrinks when cooled. It is this expansion and contraction that makes standard glass susceptible to thermal shock and shattering when rapidly cooled such as plunging the glass into ice water.
Ceramic glass such as Robax Glass®, PyroCeram Glass®, and NeoCeram Glass® have near-zero thermal expansion which makes them very resistant to thermal shattering.
