Are quartz countertops heat resistant? Sure thing, but they aren’t heatproof!


While a quartz countertop is heat resistant, it can be damaged if exposed to too much heat.


Quartz countertops are constructed with up to 90% quartz. The remainder of the material is dyes and resin. Since the resin can only resist approximately 150 degrees, placing very hot materials such as a pan immediately out of the oven will burn the countertop and cause permanent damage.


Slips happen, so you may set a hot pan on your quartz countertop and see immediate scorch marks on your countertop, usually brown or yellow. This does not mean that the countertop is completely ruined. It is an indication of a resin burn, which professionals can usually – though not always – repair.


You may also notice that moderately hot pans and pots may cause discoloration on your quartz countertop if left on the surface for long periods, which is why a hot pad or trivet should be used.


Here are some ways to prevent heat damage on your quartz countertop:


  • Protect your quartz countertops from extreme heat with hot pads or trivets. While you know that placing a hot pot on your quartz countertop can ruin it, you can sometimes forget. For functionality, keep these protective items near the stove to avoid accidentally placing hot items on the countertops.



  • Use coasters. While it is unlikely that tea and coffee mugs will burn through your quartz countertop, you do not want to risk it. Using coasters will protect your countertops from any burn and will help maintain them over time.
