Cambria is a quartz countertop surfacing product that is made from natural quartz, one of the hardest minerals on Earth. Cambria quartz is durable and more resistant to surface damage than other stones. However, natural stone surfaces can be damaged by sudden and rapid changes in temperature, especially near the edges, as well as direct and sustained heating. Therefore, it is not advisable to place hot pans directly on Cambria quartz countertops as it may cause permanent damage. To prevent potential damage to the countertops, it is recommended to use potholders, trivets, or heat-resistant mats.

What You'll Learn

Cambria quartz is not heat-proof
Quartz is quite heat resistant, up to around 400 degrees Fahrenheit (200 degrees Celsius). However, a smoking hot pan straight off the stove can damage it. The level of heat resistance depends on the quality of the quartz, so cheaper varieties may be more susceptible to damage.
Natural stone surfaces can be damaged by sudden and rapid changes in temperature, especially near the edges. Cambria may not withstand the direct transfer of heat from pots and pans and other cooking units such as electric frying pans and griddles, air fryers, slow cookers, roaster ovens, and heat lamps. Therefore, it is recommended to use a closed-weave hot pad or solid trivet, such as a breadboard, to prevent damage to the product.
If you accidentally place a hot pan on your Cambria quartz countertop, you will almost immediately see burn marks that are usually brown or yellow. This is because the resin in the quartz has burned. While this does not mean that the worktop is ruined forever, it will require repair.

Sudden temperature changes can damage the surface
Cambria is made from natural quartz, one of the hardest minerals on Earth. It is highly durable and offers superior performance. However, like other natural stone surfaces, Cambria can be damaged by sudden and rapid changes in temperature, especially near the edges.
Quartz countertops are manufactured with up to 94% quartz, with the remaining 6% being a mixture of pigments and resin. The resin component is where the issue of heat damage lies. Resin can only withstand temperatures of approximately 150 degrees Celsius, so placing very hot items like pots and pans straight from the oven or stove will burn the worktop and cause permanent damage. This damage can include warping, cracking, and discolouration.
To prevent potential damage to quartz countertops, it is recommended to use potholders, trivets, or heat-resistant mats. These items are designed to handle hot dishes and protect the worktop from excessive heat. Additionally, it is advised to avoid placing hot items directly on the countertop, especially if the surface is cold, as this sudden temperature change can cause cracking.
While high-quality quartz worktops may be more resistant to heat, it is always best to take precautions to protect your surface. By using the appropriate protective items and being mindful of temperature changes, you can help ensure the longevity and beauty of your Cambria quartz countertop.

Hot pans can cause discolouration
Cambria is a quartz countertop and surfacing product that has a variety of uses in your home or business, such as countertops, backsplashes, floor tiles, and more. Cambria is made from natural quartz, one of the hardest minerals on Earth, for superior durability and performance. However, natural stone surfaces can be damaged by sudden and/or rapid changes in temperature, especially near the edges, as well as direct and/or sustained heating of the top.
Cambria may not withstand the direct transfer of heat from pots and pans and other cooking units such as electric frying pans and griddles, air fryers, slow cookers, roaster ovens, and heat lamps. Therefore, it is recommended to use a closed-weave hot pad or solid trivet such as a breadboard to prevent heating the product.
Discolouration can occur from prolonged heat above 60°C (140°F) or very hot liquids such as boiling water, tea, or coffee being spilled on the surface. In a matter of moments after placing an object with a very high temperature, yellow or brown scorch stains appear. They are signals of the resin burn and can be caused by even moderately hot pots or pans. If you regularly put them on your quartz countertop’s surface and let them stay there, the discolouration will appear as well. Even cooling-down coffee pots can cause these marks.

Trivets and mats can protect the surface
Trivets and mats provide a protective barrier between the hot pan and the quartz surface, preventing direct heat transfer. They are designed to withstand higher temperatures than quartz countertops, making them an effective solution. The use of a closed-weave hot pad or solid trivet, such as a breadboard, is recommended by Cambria to safeguard their product from heat damage.
When selecting a trivet or mat, opt for materials that are specifically designed to handle high temperatures. These can include silicone, cast iron, or thick woven fabrics. Ensure the size of the trivet or mat is adequate to accommodate the hot pan, providing a sufficient buffer zone between the pan and the countertop.
It is important to note that while trivets and mats offer protection, they should not be relied upon for prolonged periods. Hot pans should be removed from the trivet or mat and placed on a heat-resistant surface as soon as possible. Additionally, be mindful of the weight of the hot pan to ensure the trivet or mat can bear the load without compromising its integrity or stability.
By employing trivets and mats, you can effectively safeguard your Cambria quartz countertop from potential heat damage caused by hot pans, preserving its beauty and longevity.

Burn marks may be repairable
Cambria quartz is made from natural quartz, one of the hardest minerals on Earth, and is known for its superior durability and performance. However, natural stone surfaces can be damaged by sudden and rapid changes in temperature, especially near the edges, as well as direct and sustained heating. While Cambria quartz is more resistant to surface damage than other stones, it may not withstand the direct transfer of heat from hot pans and cooking appliances.
Burn marks on Cambria quartz may be repairable, depending on the severity of the damage. If the burn marks are superficial, meaning they have only affected the surface of the quartz, they may be able to be buffed out or polished away. In some cases, a professional may need to replace the damaged section of quartz and match the polish to the surrounding area.
It is important to act quickly if a hot pan has been placed on Cambria quartz and left a burn mark. The longer the heat is applied, the deeper the damage may go. If the burn mark is only on the surface, it is important to clean the area with warm water, a soft cotton cloth, and a mild soap to remove any residue. Once the area is clean, a mild abrasive can be used with small circles and patience to try to buff out the burn mark.
If the burn mark is deeper and has affected the aggregate of the quartz, more extensive repair may be necessary. In this case, it is recommended to consult a professional to assess the damage and determine the best course of action. They may suggest repairing the damaged area by filling and polishing, or they may recommend replacing the entire section of quartz.
To prevent burn marks on Cambria quartz, it is recommended to always use a closed-weave hot pad, trivet, potholder, or solid trivet such as a breadboard when placing hot pans or appliances on the surface. These protective measures will help to distribute the heat and prevent direct contact with the quartz, reducing the risk of burn marks and other heat-related damage.
