What is Quartz?
Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The result is a very hard, non-porous surface that is resistant to scratching, staining, and heat.
The Heat Tolerance of Quartz
One of the biggest advantages of quartz over natural stone surfaces like granite is its superior resistance to heat. Quartz can withstand brief exposures to temperatures up to 212°F without any damage. This high heat tolerance makes quartz an ideal choice for kitchen countertops.
Hot Pans and Pots
Quartz countertops can handle hot pans straight from the stove or oven without issue. As long as you don’t leave a hot pan on the surface for an extended time, quartz can easily tolerate the heat. Lifting a hot pot or pan after cooking will not damage or discolor your quartz countertops.
Many home chefs use appliances like instant pots, crockpots, and electric griddles on their counter while cooking. Quartz surfaces can safely withstand the heat from these small appliances without any worries. Just don’t let them run for hours in the same spot.
Candle Warmers and Wax
Candle warmers have also become a popular home fragrance option. The gentle heat from a candle warmer will not affect quartz countertops. However, be very careful not to spill candle wax on quartz, as the wax can be difficult to remove if allowed to harden.
Protecting Quartz from Excessive Heat
While quartz has excellent heat tolerance compared to other countertop materials, there are still some limitations on the amount and intensity of heat it can handle:
- Very High, Direct Heat – Direct, sustained contact with temperatures over 300°F could potentially damage quartz and cause cracks or discoloration. Never place extremely hot cookware like cast iron skillets directly on quartz.
- Prolonged Exposure – While brief contact with hot items is fine, leaving a hot pan or appliance running for an extended time in one place could be problematic. Move items after a few minutes to avoid excess concentrated heat exposure.
- Rapid Temperature Changes – Although quartz withstands heat well, sudden shifts from very hot to cold could create issues. Allow hot pans to cool somewhat before placing on quartz, and don’t follow a hot pan with an icy cold one in the same spot. Gradual temperature changes are best.
- Heat-Generating Appliances – Small kitchen appliances like instant pots and crockpots are fine, but avoid placing full-size ovens or stovetops flush against quartz counters. The extreme heat could cause damage over time.
Protecting Your Quartz Countertops from Heat
To be extra cautious with your quartz around high temperatures, consider these tips:
- Use trivets or hot pads under very hot pots and pans, especially cast iron.
- Allow pans to cool for a few minutes before directly placing on quartz.
- Avoid leaving hot pans stationary on the same spot for more than 10-15 minutes.
- Use a cutting board under portable grill tops and appliances.
- Don’t let heating appliances run for hours with direct contact against the quartz.
- Always use a coaster under hot mugs and cups.
- Add a heat barrier between quartz and extreme heat sources like ovens.
Can Quartz Withstand Heat from Curling Irons?
One common question is whether hot tools like curling irons and hair straighteners can damage quartz counters. The answer is yes, quartz can withstand the brief contact from a hot iron or other heated styling tool without issue. However, prolonged, direct heat could be problematic. Allow curling irons to cool somewhat before setting them down, and don’t let them sit in one spot for an extended time against the quartz. It’s also wise to use a heat resistant mat or plate under hot styling tools.
Is Quartz Heat-Resistant?
In summary, quartz has excellent heat resistance compared to many other countertop materials. Its resilience against moderate heat exposure is one of its greatest assets. However, quartz does have its limits, and prolonged, intense, or rapid heat can cause damage. With some simple precautions, you can comfortably use quartz around most everyday cooking and household heat sources. Just be careful to avoid sustained direct contact with extreme temperatures. The heat tolerance of quartz gives homeowners confidence cooking hot meals while still maintaining the beauty of their counters.
FAQ About Using Quartz Countertops Around Heat
Below are some frequently asked questions about exposing quartz countertops to high temperatures from cooking, appliances, and more:
Can you put a hot pan on quartz?
Yes, quartz countertops can handle a briefly placed hot pan straight from the oven or stove without issue. Avoid leaving it in one spot for prolonged time periods. Allow extra hot pans to cool slightly before placing directly on quartz.
Does quartz burn or stain?
Quartz resists burning or staining from moderate heat exposure. However, prolonged direct contact with extremely high temperatures above 300°F could potentially discolor or damage the surface.
Can you put a crockpot or instant pot on quartz?
Yes, you can safely place heated small kitchen appliances like crockpots, instant pots, or electric griddles directly on quartz counters. Just don’t allow them to run for hours in one place.
Will a curling iron damage quartz?
Brief contact from a curling iron or hair straightener will not harm quartz. But avoid leaving hot irons stationary on the surface for extended periods, as prolonged heat could cause damage.
Can quartz crack from heat?
Exposing quartz to sudden temperature extremes or very high direct heat for long periods can potentially cause cracks or fissures in the surface. Avoid quartz contact with temperatures above 300°F.
Can you put a griddle on quartz?
Portable electric griddles are fine for temporary use on quartz but should not be allowed to run in one spot for hours at a time. Use a trivet for extra protection below the griddle.
Is quartz ruined by heat?
Quartz has high heat tolerance and is not easily ruined by moderate heat exposure in normal residential use. But extreme, sustained high temperatures can damage quartz over time. Follow tips to prevent excess heat.
Does quartz melt?
No, quartz countertops will not melt from standard household heat sources like stovetops, cookware, or appliances. But quartz can become damaged or discolored if exposed to temperatures above 300°F.
- Quartz countertops have excellent resistance to moderate heat, making them very durable in kitchens.
- Brief contact with hot pans, appliances, or tools will not harm quartz surfaces.
- Take care to avoid prolonged direct exposure to extreme heat above 300°F to prevent possible damage.
- Allow extra hot items to cool somewhat before placing directly on quartz counters.
- Use trivets, cutting boards, or heat mats when necessary to prevent excess heat transfer.
- With proper care around high temperatures, quartz makes an ideal countertop for busy kitchens.
