What You'll Learn
Granite countertops are heat-resistant, but not heatproof
Granite is a tough igneous rock formed from volcanic fire. This geologic process allows granite to withstand tremendous temperatures—significantly higher than 1,000°F—and it has a melting point of 2,300°F. This level of heat resistance has led many people to believe it is safe to put hot pans on granite countertops.
While granite is strong enough to withstand the heat of a hot pan without melting or cracking, it is not totally heatproof. Granite can handle brief encounters with hot items, but over time, exposure to excessive heat can weaken the seal on your granite countertop. This can leave the surface more exposed to staining and liquid damage. Thermal shock can also occur when hot pans are placed on the surface of a granite countertop. While rare, thermal shock can potentially occur when granite is exposed to extreme temperatures, causing the stone surface to undergo a drastic change in temperature in a short time. This can result in small cracks in your countertop.
To avoid damaging your granite countertop, it is recommended to use a trivet, potholder, or cutting board when placing hot items on the surface. This will help to protect the sealant and reduce the risk of staining and cracking. Granite countertops should also be re-sealed about once per year to maintain their durability and stain resistance.
In summary, while granite countertops are highly heat resistant, they are not entirely heatproof. To ensure the longevity of your granite countertop, it is best to take precautions when placing hot items on its surface and to maintain the sealant.

Sealants can be damaged by excessive heat
Granite is a tough igneous rock formed from volcanic fire. This process occurs at very high temperatures, allowing granite to withstand tremendous temperatures—significantly higher than 1,000°F—and it has a melting point of 2,300°F. This level of heat resistance has led many people to believe it is safe to put hot pans on granite countertops.
While you can technically place a hot pan directly on a granite countertop for a short period without causing long-term damage, it is not advisable. Granite will absorb and retain heat when a hot pan is placed on it. When the pan is removed, there will be no visual indication that the countertop is extremely hot, creating a significant safety hazard. If someone touches the countertop shortly after the pan is removed, they could suffer a serious burn.
To avoid these issues, it is recommended to use a trivet, potholder, or cutting board when placing hot pans on a granite countertop. These barriers will help to protect the sealant and reduce the risk of staining, cracking, and safety hazards.

Thermal shock is rare but possible
Granite is a tough igneous rock that is formed by the cooling and solidification of lava or magma at extremely high temperatures. This means that it is highly heat resistant and can withstand tremendous temperatures—significantly higher than 1,000°F—and has a melting point of 2,300°F. Therefore, placing a hot pan on a granite countertop will not damage the granite.
However, while granite itself is resistant to heat, the sealants used on granite countertops can weaken from excessive heat. Sealants are necessary for preventing stains and other damage. Over time, exposure to high temperatures can weaken the seal, leaving the surface more exposed to staining and liquid damage. This is why it is recommended to use trivets, hot pads, or potholders when placing hot pans on granite countertops.
Thermal shock is a potential risk when placing hot pans on granite countertops. This occurs when a material undergoes a drastic change in temperature over a short period of time. While rare, thermal shock can occur when granite is exposed to extreme temperatures, causing the stone surface to quickly undergo a significant temperature change. This can result in small cracks in your countertop. The risk of thermal shock is exacerbated if the temperature fluctuation is uneven throughout the granite surface, as tensile stress between the surface and inner layers develops.
Therefore, while it is unlikely that placing a hot pan on a granite countertop will cause damage, it is still recommended to use a protective barrier to reduce the weakening of sealants and the risk of thermal shock. Granite can absorb and retain heat, creating a safety hazard as the countertop surface may be extremely hot even after the pan is removed.

Granite can withstand and conduct heat
Granite is a tough igneous rock formed from volcanic fire and is highly resistant to heat. It can withstand tremendous temperatures—significantly higher than 1,000°F—and has a melting point of 2,300°F. This level of heat resistance leads many people to believe it is safe to place hot pans on granite countertops.
While granite can withstand the heat of a hot pan without melting or cracking, it is not recommended to place hot pans directly on a granite countertop. Granite can handle brief encounters with hot pots, but over time, exposure to excessive heat can weaken the seal on the granite, leaving the surface more susceptible to staining, liquid damage, and thermal shock. Thermal shock is rare for granite countertops but can occur when granite is exposed to extreme temperatures, causing the stone surface to undergo a rapid and significant temperature change.
Granite will absorb and retain heat when a hot pan is placed on it. When the pan is removed, the countertop will remain hot and could burn someone. Therefore, it is best to place a protective barrier, such as a trivet, potholder, or pad, between the hot pan and the granite surface.
Granite countertops require proper care and maintenance to extend their lifespan and keep them looking new. They should be sealed annually to protect against stains, liquid damage, and other issues. When cleaning, it is important to use a granite cleaner rather than soap and water and to avoid abrasive products.

Use trivets, hot pads, and potholders
Granite is a tough igneous rock that is formed by the cooling and solidification of lava or magma at extremely high temperatures. This makes it highly heat resistant, with a melting point of 2,300°F. So, while granite countertops can withstand brief encounters with hot pans, it is not recommended.
Using trivets, hot pads, and potholders is a good way to protect your granite countertops from hot pans. These protective barriers will help to prevent thermal shock, which can occur when granite is exposed to extreme temperatures or rapid temperature changes. While rare, thermal shock can cause small cracks in your countertop as the stone surface undergoes a significant temperature change.
Trivets, hot pads, and potholders also help to reduce the weakening of sealants, staining, and cracking. Sealants are necessary for preventing stains and other damage, and exposure to excessive heat can weaken them over time. By using a protective barrier, you can avoid creating a safety hazard. Granite will absorb and retain heat, so placing a hot pan directly on the countertop can result in a hot granite surface that could burn you or someone else.
In addition to trivets, hot pads, and potholders, it is recommended to use cutting boards during meal preparation and coasters underneath beverage glasses to further protect your granite countertops.
