How to Protect Quartz Countertops from Heat Damage

Quartz countertops are a favorite in modern kitchens for their durability and non-porous nature. However, many homeowners are surprised to learn that quartz is not heat-proof.

Why Quartz is Vulnerable

Unlike natural stone like granite, engineered quartz is made of approximately 90-95% crushed stone bound together by polymer resins. These resins are susceptible to "thermal shock."

What Happens During Thermal Shock?

When a scorching hot pot (often exceeding 300°F) is placed directly on a cool quartz surface, the resin can expand rapidly or even melt. This leads to:

1. Discoloration: Scorch marks that appear as yellow or brown stains.
2. Cracking: Sudden expansion can cause the slab to hairline fracture.

Using Trivets the Right Way

To protect your investment, always use a high-quality trivet.

Look for These Features:

• Elevated Design: A trivet with legs or a thick profile creates an air gap between the heat source and the quartz.
• Non-Slip Feet: Ensure your trivet has rubber or vinyl feet to prevent scratching the polished quartz surface. See our Trivet Feet page for more information.
