Quartz Plus is more heat resistant than other natural stone surfaces including most kinds of granite, marble and limestone; and it is not affected by temperatures lower than 110℃. However, like all stone materials, the Quartz Surface stone can be damaged by sudden and rapid temperature changes. Therefore protective trivets and heat pads must always be used underneath cookware such as skillets, saucepans, pots or dishes when removing hot items directly from any heat source like oven, cook top or microwave and placing onto the Quartz Plus surface. We suggest that hot pots, electric frying pans, oven trays and pans never be directly placed on the counter top surface, as prolonged or sudden extreme temperature changes can permanently damage the material which is not covered under this warranty.
