Quartz countertops are made with up to 90% quartz, with the remaining material being pigments and resin. While they are heat-resistant, they are not heatproof, and can be damaged by excess heat. The resin in quartz countertops can only withstand temperatures of around 150°C, so placing hot items such as pans directly onto a quartz countertop can cause scorch marks and permanent damage. To prevent this, it is recommended to use protective items such as coasters, potholders, trivets, or heat-resistant mats when placing hot items on quartz countertops.

Heat-resistant mats, trivets, and coasters can protect quartz countertops from hot pans
It is not advisable to place a hot pan directly on a quartz countertop as it can cause permanent damage. Quartz countertops are made with up to 90% quartz, with the remaining material being pigments and resin. Since resin can only withstand temperatures of approximately 150 degrees, placing hot items on the surface will cause scorch marks and discolouration.
To protect your quartz countertops, it is recommended to use heat-resistant mats, trivets, or coasters. These protective items are designed to shield your countertops from heat damage and stains. Trivets, for example, are designed to elevate a hot pan above the surface, reducing the risk of heat transfer. Modern trivets come in a variety of designs, materials, colours, sizes, and styles, allowing you to choose an option that suits your needs and aesthetics. Some popular materials for trivets include silicone, cast iron, ceramic, cork, bamboo, wood, stone, and metal. Each material has its advantages and disadvantages in terms of heat resistance, durability, weight, and appearance. For instance, silicone trivets are inexpensive, lightweight, durable, and heat resistant, but some may not prefer their plasticky appearance. On the other hand, cast iron trivets are heavier and more visually appealing, but the enamel coating can chip if dropped.
Coasters are another essential item to protect your quartz countertops. While it is unlikely that tea or coffee mugs will burn through the quartz, using coasters will provide an extra layer of protection and help maintain the countertop over time. Similarly, heat-resistant mats, such as hot pads, can be placed underneath hot pans to prevent heat damage. These mats and trivets are especially important when dealing with very hot items like pans straight out of the oven, which can cause immediate and permanent damage to the resin in the quartz countertop.
By investing in heat-resistant mats, trivets, and coasters, you can protect your quartz countertops from heat damage caused by hot pans and pots. These protective items act as a barrier between the hot surface and the countertop, preventing scorch marks, discolouration, and permanent damage. Remember to keep these items near your stove to ensure convenience and functionality in your kitchen.

Quartz countertops are heat-resistant, but not heat-proof
Quartz countertops are highly durable and resistant to heat, but they are not entirely heat-proof. This means that while they can withstand moderate heat, excessive heat can cause damage. The resin in quartz countertops, which makes up about 6-10% of the material, has a low heat threshold of approximately 150°C (300°F). As a result, placing very hot items such as pans straight out of the oven directly on the quartz countertop can burn the surface and cause permanent discolouration or even cracking.
To protect your quartz countertop from heat damage, it is recommended to use heat protectors such as coasters, potholders, hot pads, and trivets. These protective items act as a barrier between the hot object and the countertop, preventing direct heat transfer. By using these simple precautions, you can safeguard your quartz countertop from potential damage caused by excessive heat.
It is worth noting that the quality of the quartz countertop can also play a role in its heat resistance. Higher-quality quartz countertops may be more resistant to heat and less prone to damage. Additionally, maintaining your quartz countertop by regularly cleaning it and avoiding spills, especially acidic substances, can help prolong its durability.
While quartz countertops are not entirely heat-proof, taking these precautionary measures will help ensure their longevity and maintain their aesthetic appeal. By being mindful of the temperature of items placed on the surface and utilising heat protectors, you can effectively prevent heat damage to your quartz countertop.

Placing hot pans on a quartz countertop can cause permanent damage
Placing hot pans on a quartz countertop is not advisable as it can cause permanent damage. Quartz countertops are made with up to 90% quartz, with the remaining material being pigments and resin. The resin, which has a low heat threshold, can only withstand temperatures of approximately 150°C (300°F or 60°C according to some sources). As such, placing very hot materials, such as pans straight out of the oven, on a quartz countertop will burn the surface and cause permanent damage.
The most common result of placing a hot pan on a quartz countertop is a discoloured ring on the surface, where the resin has been scorched and darkened. These scorch marks usually appear as yellow or brown stains. While this does not mean that the countertop is completely ruined, it will require repair. Professionals can usually repair resin burns, although not always.
To prevent damage to quartz countertops, it is recommended to use heat protectors such as coasters, potholders, hot pads, and trivets when placing hot items on the surface. These protective items should be kept near the stove or countertop to avoid accidentally placing hot pans directly on the quartz surface. Additionally, it is important to be cautious when using hair tools such as curling irons and straightening plates on quartz countertops in bathrooms, as the hot parts of these tools can also leave scorch marks.
While high-quality quartz countertops may be more resistant to heat, it is still best to take precautions and avoid placing hot pans directly on the surface. Regular heat application can also cause discolouration, melting, and peeling of the sealant on a slab countertop. Therefore, it is important to use trivets or heat-resistant mats when handling hot items near quartz countertops to ensure their durability and longevity.
