Quartz countertops are resistant to heat to a certain extent, but they aren’t completely heatproof. Direct and prolonged exposure to high temperatures could cause the surface to crack or discolor. It’s recommended to always use trivets or hot pads when placing hot cookware or dishes on the countertop to prevent any damage. Ideally, you’ll avoid exposing the countertop to temperatures exceeding 150 °F (65 °C) to prevent any potential damage to the surface. Additionally, sudden temperature changes, such as placing hot cookware on a cold countertop, should be avoided as this can cause thermal shock and damage.
