Recycled glass countertops are composite materials, usually composed of glass shards embedded in a resin or cement binder. The glass itself has a high heat tolerance; however, the binder material may have different thermal expansion characteristics. In extremely hot climates or with high-heat exposure, the difference in expansion rates can create internal stress. While these surfaces are generally categorized as heat-resistant, they are not heat-proof. To maintain the integrity of the surface and prevent thermal shock—which can lead to cracking, especially in areas with thin profiles—it is strongly recommended to use trivets or heat pads for hot cookware.

Are recycled glass countertops prone to thermal shock in hot climates?
Recycled glass countertops are typically highly resistant to heat, but they are not entirely immune to thermal shock. Rapid, extreme temperature changes, such as placing a frozen item directly next to a boiling pot on a thin section of glass, can cause localized stress. While they perform well in most environments, always use trivets for hot cookware to prevent any risk of cracking. Consult your manufacturer for specific thermal tolerance specifications.
