It is normally advised to steer clear of putting cookware or pans that are extremely hot directly onto quartz countertops. Although quartz is more heat-resistant than materials like wood or laminate, the surface may get damaged by abrupt or severe temperature changes.
Quartz can endure moderate heat, although thermal shock can occur from extended exposure to high temperatures (over 300°F or 150°C) or from direct contact with extremely hot pans that have just been taken from the stove or oven. This heat shock could cause the glue holding the quartz particles together to weaken, shatter, or become discolored.
Use trivets, hot pads, or heat-resistant mats below hot cookware or dishes to form a barrier between the surface and the heat source, protecting your quartz worktops from heat damage. Over time, this preventative measure will help preserve the aesthetic appeal and structural soundness of your quartz countertops.
