Hot Pots And Quartz: A Cautionary Tale

Quartz countertops are durable and luxurious, but they are not indestructible. While they are heat-resistant, they are not heat-proof, and can be damaged by high temperatures. For example, placing a hot pot or frying pan directly on a quartz countertop could damage it. Prolonged exposure to high heat can cause scorch marks or discolouration, and sudden placement could cause cracking due to thermal shock.

Trivets and hot pads can be used to protect quartz countertops from hot pots

Trivets and hot pads are essential for protecting quartz countertops from hot pots. While quartz is an extremely durable and heat-resistant material, it is not heat-proof and can be damaged by excessive heat.

Quartz countertops are made from ground quartz combined with polymer resins. The resins used to seal the quartz slabs together lower their heat resistance. As a result, placing a hot pot directly on a quartz countertop can cause scorch marks, discolouration, or cracking.

To prevent heat damage, it is recommended to always place hot pots, pans, and dishes on trivets or hot pads. These protective barriers will safeguard your quartz countertops from excessive heat that could lead to discolouration or cracking. By taking this simple precaution, you can maintain the beauty and longevity of your quartz surfaces.

There are various types of trivets and hot pads available, made from materials such as silicone, cork, bamboo, wood, cast iron, or fabric. When choosing a trivet or hot pad, consider its heat resistance, ease of cleaning, and aesthetic appeal. Some trivets are designed with non-slip features or raised surfaces to further protect your countertops. You can find these protective items in different colours, sizes, and styles to suit your kitchen décor.

In addition to using trivets and hot pads, there are other precautions you can take to protect your quartz countertops. For example, you can use coasters for hot drinks, install high-quality quartz that offers better heat resistance, and be mindful of sunlight exposure, as prolonged exposure to direct sunlight can cause discolouration over time.

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. They can withstand temperatures of up to 300° Fahrenheit (or 150° according to some sources). Beyond this threshold, the resin binders within the quartz slab can change their chemical state, often resulting in discolouration or even cracking of the surface.

While a hot cup of coffee or a warm plate of food won't cause any harm, a searing hot pot or frying pan placed directly on the quartz surface could damage it. The heat from these items can leave scorch marks or cause discolouration. Additionally, the sudden change in temperature can cause thermal shock, resulting in cracks.

To protect your quartz countertops, it is recommended to use trivets, potholders, or hot pads when placing hot items on them. By taking these simple precautions, you can keep your quartz countertops looking shiny and new for years to come.

It's also worth noting that while quartz countertops are highly durable, they are not indestructible. Regular maintenance and care, such as wiping them down with a quartz cleaner, will help prolong their beauty and functionality.

Exposure to temperatures over 300°F could damage the countertop

Exposure to temperatures over 300°F could damage your quartz countertop. While quartz is a highly durable material, it is not completely heat-proof. The resin binders within the quartz slab can change their chemical state when exposed to temperatures above 300°F, which often results in discolouration.

Quartz countertops are made from about 90-94% ground quartz, with the remaining percentage consisting of polymer resins and, sometimes, bits of recycled glass or metallic flecks. The resins help to keep the countertop from scratching or staining, so you don't need to treat your quartz countertop with a sealant as you would with natural stone. However, the resin also lowers the heat-resistance level of the countertops.

The heat from a hot cup of coffee or a microwaved plate is unlikely to cause any harm to a quartz countertop. However, a searing hot pot or frying pan placed directly on the surface could damage it. Prolonged exposure to high heat can leave scorch marks or discolouration on the countertop, and can even cause cracking due to thermal shock.

To protect your quartz countertop, it is recommended to always place hot pots, pans, and dishes on trivets or hot pads. It is also a good idea to keep a few coasters on your kitchen countertops that are easily accessible, so you can reach for a coaster when placing your morning coffee on the counter.

In addition to being heat-resistant, quartz countertops offer several other advantages. They are non-porous, easy to clean and maintain, and food-safe, resistant to contaminants like bacteria, viruses, and mould. They also provide outstanding strength and durability, ranking at about 7 on the Moh's hardness scale.

Thermal shock from hot pots can cause cracks in the quartz surface

While quartz countertops are highly durable and heat-resistant, they are not entirely heatproof. Placing hot objects on a quartz surface can cause thermal shock, leading to cracks in the surface.

Quartz countertops are made from about 90-94% ground quartz, with the remaining percentage consisting of binding agents like resin and polymer. These binding agents are what make quartz countertops susceptible to heat damage. When a hot pot or pan is placed directly on the surface, the resin can burn, causing scorch marks and discolouration.

The resin in quartz countertops typically has a heat threshold of around 150°F. In contrast, the quartz stone can withstand temperatures up to 300°F. Therefore, it is crucial to avoid placing extremely hot objects on quartz countertops to prevent thermal shock and potential cracking.

To protect your quartz countertops from heat damage, it is recommended to use trivets or hot pads under hot pots and pans. This simple precaution will help maintain the beauty and durability of your countertops for years to come. By taking these preventive measures, you can avoid the risk of heat damage and ensure the longevity of your quartz surfaces.

Scorchmarks and discolouration are common types of damage caused by hot pots

Quartz countertops are made from about 90% ground quartz, combined with polymer resins. The resins help to keep the countertop from scratching or staining, but they also lower the heat-resistance level of the countertops. As a result, placing a very hot pot or pan directly on a quartz countertop can lead to scorchmarks and discolouration. Prolonged exposure to high heat can cause these marks and discolouration, and even cooling coffee pots can cause these marks over time.

To prevent scorchmarks and discolouration, it is recommended to always place hot pots, pans, and dishes on trivets or hot pads, rather than directly on the countertop. This will protect the quartz from excessive heat and help to keep it looking new. Another option is to use coasters under hot mugs and cups to protect the countertop from heat marks.

If scorchmarks or discolouration do occur, it may be possible to remove them by cleaning the counters with mild soap and warm water, or by creating a mixture of baking soda and water and applying it to the affected area. However, removing discolouration from quartz is not always possible, and in some cases, it may be necessary to replace the countertop.
