Pyroceram glass is a type of high temperature glass similar to Neoceramic, Pyrex, and Robax glass. We feel that Pyroceram is a superior ceramic glass product. Invented in the 1950's by Corning® to be a consistent transparent crystaline glass that resisted shattering for high heat applications. Pyroceram wood stove glass has a thermal shock rating of 1380° F . We recommend that a non-combustible gasket is used in all applications if possible.
Pyroceramic glass specifications.

The physical and performance characteristics of PYROCERAM III Brand Clear Glass Ceramic and CLEARVIEW PLUS Coated PYROCERAM III for wood, coal, pellet, and gas stoves. A separate product specification will exist for every product code which defines the nominal dimensions and tolerances for that item. The product specification will take precedence over this specification if a discrepancy exists.

3. VISUAL AND SURFACE APPEARANCE The parts cut to the client’s dimensions are divided into 2 areas according to the condition of use. The first part is the central area which is visible in the finished appliance. The second part is the peripheral area which is hidden by the frame in the finished appliance. The Pyroceramic Glass appearance criteria is evaluated from 1.0 meter away, held vertical in front of a light source corresponding to the same level of brightness as in the practical use of the product. The defects that cannot be measured are estimated by comparison with limit samples. The limit sample is the maximum permissible level of imperfection.

Pyro-Ceramic glass is a heat-resistant glass-ceramic that can withstand extremely high temperatures. In reality, it is a clear version of ceramic. Pyro-Ceram was first used to create casserole dishes and saucepans. Manufacturers have extended the use of Pyro-Ceram to ovens, broilers, heat insulators, missiles and lighting. Pyro-Ceram is no longer used just for dishware. It is also helps in reducing UV light waves.
Manufacturers use a special rating system for evaluating the strength of ceramic glass when shocked by a change in temperature. This rating system is called Thermal Shock Resistance. Pyro-Ceram has a high thermal shock resistance. You could pour cold water on hot Pyro-Ceram, it will not crack or shatter the way standard glass would. Having a high thermal shock resistance rating makes Pyro-Ceram the best choice for replacement glass in items that are exposed to high temperatures.
This is why makes it an excellent choice for fireplaces replacement glass and wood stove replacement glass.
