High-Temp Glass for Stoves & Fireplaces

Glass in stoves and fireplaces tends to be either tempered glass or glass ceramic (often referred to by brand name, such as Neoceramic© and Robax©).

high-temperature glass in a fireplaceTempered glass can withstand temperatures of up to 500° F, and it is sometimes suitable for low-temperature gas stoves. At temperatures over 500° F, tempered glass can lose its temper over time. At 600° F, tempered glass can lose over 50% of its temper in just one year.

For high-temperature stoves, and especially for wood-burning fireplaces, glass ceramic is the appropriate choice. It can withstand continuous temperatures of nearly 1300°F, and has excellent thermal shock resistance and impact strength. Unlike tempered glass, its heat-resistant properties show no reduction over time.
