Understanding the Heat Resistance of Granite Countertops

At Fox Granite, we often receive questions about the heat resistance of granite countertops. This crucial feature can make all the difference in a busy kitchen. Let's dive into the heat-resistant properties of granite, how much heat these countertops can endure, and how they stack up against other materials, such as quartz. Continue reading to learn more about the heat resistance of granite countertops.

Are Granite Countertops Heat Resistant?

The simple answer is yes, granite countertops are heat resistant. Granite is formed through the cooling and solidification of magma or lava, which means it's created under intense heat conditions. This natural stone can handle high temperatures, making it a great choice for kitchens where hot pots and pans are common. But, that doesn’t mean you should place hot cooking utensils directly on your countertop. Using a trivet or pot holder is the best way to ensure the sealant of your granite countertop, which is not as heat resistant as the stone itself, does not get damaged.

Are Granite Countertops Heat Proof?

While granite countertops are indeed heat resistant, it's essential to understand that they are not entirely heatproof. Being heat resistant means they can withstand heat to a certain degree. However, extreme or prolonged exposure to high heat can potentially damage the granite, especially if it's a sudden temperature change, a phenomenon known as thermal shock. Thermal shock is not common, but it is possible, especially when the countertop is cold like on a winter day.

How Much Heat Can Granite Countertops Withstand?

On average, a granite countertop can withstand temperatures up to 1200 degrees Fahrenheit without experiencing immediate damage. However, this does not mean you should place hot items directly on the granite surface. The sealant applied to granite countertops to protect against stains and scratches is less heat resistant than the stone itself. This sealant may get damaged at much lower temperatures, usually around 450 to 500 degrees Fahrenheit.

Can Granite Countertops Burn?

Granite itself is unlikely to burn or melt unless exposed to extreme temperatures well beyond what you would find in a home kitchen. However, as mentioned above, the sealant on granite countertops can indeed be damaged by high heat. Sealant being damaged by high heat does have the potential to look similar to a burn mark from holding a lighter to paper or in some cases, melted plastic.

Granite vs. Quartz Heat Resistance

While both granite and quartz countertops are popular choices for kitchens, when it comes to heat resistance, granite has a slight edge.Quartz countertops are engineered stone products that contain a high percentage of quartz, a very hard mineral, but they also contain resins and pigments. These resins are not as heat resistant as granite, making quartz countertops more susceptible to damage from hot pots and pans.
