What Temperature Can Quartz Countertops Withstand?

Quartz countertops are an increasingly popular choice for kitchen and bathroom renovations due to their durability, aesthetic appeal, and low maintenance requirements. One of the most frequently asked questions about quartz countertops is how much heat they can withstand before becoming damaged. Here is a detailed overview of the heat tolerance of quartz countertops.

What Is Quartz?

Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The quartz content typically makes up 90-94% of the material, while the rest is polymer resins that bind the quartz particles together.

The resins make the countertop non-porous, resistant to scratches and stains, and allow the material to be molded into different shapes and forms. The end result is a hard, durable surface that maintains its shine and appearance with minimal upkeep.

How Heat Resistant Are Quartz Countertops?

One of the biggest benefits of quartz countertops is that they are more heat resistant than many other countertop materials. Here are some specifics on the heat tolerance of quartz:

  • Resistance to thermal shock – Quartz has very low thermal conductivity, meaning it resists thermal shock damage from rapid temperature changes better than other stones.
  • Resistant up to 212°F direct heat – Quartz can withstand temperatures up to 212°F direct heat before possible damage occurs. This means it can handle hot pots and pans straight from the stove or oven.
  • Short-term heat threshold around 300°F – Quartz can tolerate brief contact with temperatures up to about 300°F. However, exposing it to this level of heat repeatedly is not recommended.
  • Prolonged heat above 300°F can cause damage – Exposing quartz countertops to temperatures above 300°F for an extended period of time can potentially cause cracks, discoloration, or other damage.

So in summary, for everyday cooking tasks quartz has excellent heat resistance. But the material does have its limits, and prolonged exposure to extreme heat above 300°F is not advisable.

Tips for Protecting Quartz Countertops from Heat Damage

To get the most life out of your quartz countertops and avoid unnecessary damage, follow these simple tips:

  • Use trivets or hot pads – Placing a hot pan, pot, or other heated item directly on the counter without a barrier can put the surface at risk. Use a trivet, potholder, or hot pad whenever possible.
  • Give space for cooling baked goods – When removing hot dishes from the oven, allow them extra space to cool on the countertop before touching them directly to the surface.
  • Avoid prolonged contact with heat – While brief contact with hot items is OK, keeping a hot pot or appliance in one spot for a prolonged period can radiate enough heat to damage the countertop over time.
  • Watch for signs of damage – Look for any cracks, discoloration, or chipping around areas that encounter heat, and discontinue exposing that spot to high temperatures.
  • Have it re-sealed periodically – The resin sealant on quartz can wear down from normal use over time. Having it re-sealed every 1-2 years will maintain its heat protection.

By using reasonable care, your quartz countertops should stand up well against normal everyday cooking use without any problems. Keeping the surface away from extreme or prolonged heat exposure will help prevent unnecessary damage. With proper maintenance, quartz countertops can stay looking pristine for many years.

Frequently Asked Questions

Can I put a hot pan directly on my quartz countertop?

Yes, quartz can withstand the direct heat of a hot pan fresh from the stove or oven, up to about 212°F. However, it is still best practice to use a hot pad or trivet when possible to maintain the long-term integrity of the surface.

How hot can quartz get before it burns?

Prolonged direct heat above 300°F has the potential to damage quartz countertops. Temperatures approaching 300°F can be briefly tolerated, but the surface should not be exposed repeatedly to this level of heat.

Can quartz crack from heat?

Yes, quartz can potentially crack if exposed to extreme heat above 300°F for an extended period of time. Thermal shock from rapid temperature changes can also create hairline cracks or fissures over time. Using reasonable care will prevent heat damage.

Is quartz more heat resistant than granite?

Quartz and granite have somewhat comparable heat resistance, both handling temperatures up to about 300°F before possible damage. Neither surface should have extremely hot cookware or appliances left on them for prolonged periods.

Does quartz melt under heat?

No, quartz does not melt under normal cooking temperatures. It does soften slightly when exposed to very high heat which can lead to scorch marks. But quartz will not melt or burn like plastic when subjected to heat from stovetop cooking.


With proper care, quartz offers exceptional resistance against heat damage from routine kitchen use. Simple precautions like using hot pads and avoiding prolonged direct contact with extreme heat will ensure your quartz countertops withstand years of cooking. Following the temperature thresholds and tips provided helps prevent cracks, discoloration, and other problems. Thanks to its durable composition, quartz continues to be one of the most popular options for kitchen countertops today.
