Quartz countertops are an increasingly popular choice for kitchen and bathroom renovation projects. Not only are they attractive and available in a wide range of colors and patterns, but they are also praised for being durable, low-maintenance, and heat resistant. But just how resistant to heat are quartz countertops? Here is an in-depth look at whether quartz countertops can handle the heat.
What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The quartz content typically makes up 90% or more of the material. Polymer resins act as a binder to hold the quartz particles together. Color pigments are added to achieve the desired color and pattern.
The combination of quartz minerals and polymers creates a very hard, non-porous surface that stands up well to stains, scratches, chips, and heat. It is even more durable than natural stone surfaces like granite. For this reason, quartz has become a go-to choice for busy kitchens and bathrooms.
Heat Resistance of Quartz
One of the most appealing characteristics of quartz countertops is their ability to withstand heat. Here are some key facts about the heat resistance of quartz:
- High heat tolerance – Quartz has a very high heat tolerance compared to other countertop materials. It can withstand temperatures up to 300°F before any damage occurs.
- Does not burn or scorch – If a hot pan is left on a quartz countertop, it will not burn or scorch the surface like some other materials might.
- No permanent damage from short heat exposure – Quartz can withstand brief heat exposures up to about 300°F without any permanent damage. The material will not melt or discolor.
- Can handle common kitchen heat sources – Quartz countertops can stand up to typical kitchen activities like placing hot pots and pans on them, setting a warm pan from the oven on the surface, etc.
- Not affected by prolonged lower heat exposure – Leaving a crockpot, warming tray, or other low-heat source for a prolonged time typically will not impact a quartz countertop.
- Possible short-term marks from extreme heat – Exposing quartz countertops to extreme direct heat from something like a frying pan or iron could potentially leave temporary marks or discoloration. However, this damage is only superficial and can usually be sanded out.
- Permanent damage from sustained extreme heat – While quartz has excellent heat resistance overall, excessive sustained heat over 300°F could potentially cause permanent damage. Quartz manufacturers do not recommend exposing the material directly to extreme heat sources like stove burners or grill surfaces.
Best Practices for Using Quartz Countertops Around Heat
While quartz has very good heat tolerance, there are some best practices to follow to make sure your countertops stay in great condition:
- Use trivets or hot pads under any extremely hot cookware, like pans fresh from the stove or oven.
- Don’t put hot cookware directly over an undermount sink area, as this concentrated heat can damage the adhesive.
- Don’t expose quartz directly to open flames.
- Don’t use quartz near or around wood-burning stoves or fireplaces.
- Avoid letting an exposed burner flame or electric cooker directly touch a quartz surface.
- Don’t place quartz near temperatures that exceed 300°F for a prolonged time.
Following these simple precautions will ensure you get the most out of the natural heat resistance of quartz. Exercise some care around extreme heat sources, but otherwise feel free to use your quartz countertops without worry! They can handle everyday cooking tasks remarkably well.
Is a Quartz Countertop Heat Resistant?
In summary, yes – quartz countertops are highly heat resistant and able to withstand normal everyday cooking temperatures and brief exposures to more extreme heat. This makes them a very durable and safe choice for kitchens and bathrooms. With some simple precautions around extreme temperatures, quartz countertops can look beautiful for years of cooking and entertaining. Their thermal performance is a major reason for their popularity among homeowners, designers and renovation experts.
Frequently Asked Questions About Quartz Countertops and Heat
Here are answers to some common questions about using quartz countertops around heat sources:
Can I put a hot pan on a quartz countertop?
Yes, you can place a hot pan straight from the stove or oven directly onto a quartz countertop without worry. The high heat tolerance of quartz means it can handle the heat without any damage. Using a trivet is still recommended to maintain the surface over time.
Can I cut food directly on quartz countertops?
Absolutely. Quartz stands up well to having food prepped and cut directly on its surface. Just make sure to avoid any hard impacts from utensils that could potentially nick the material.
Do I need to use trivets with quartz countertops?
Trivets are not mandatory, but still recommended for very hot pots and pans to prevent any potential marks over time. Quartz can withstand normal cookware heat though.
Is it okay to place quartz near ovens or stoves?
Yes. Quartz can withstand the typical heat given off by kitchen ovens and stoves. Just don’t let direct open flames make prolonged contact with the surface.
Can hot hair tools damage quartz?
Setting down a hot curling iron or hair straightener for a brief time is okay, but prolonged heat exposure at high temperatures could potentially damage the surface.
Does quartz discolor when exposed to heat?
Quartz does not normally discolor from typical household heat exposure. Only extreme, sustained heat well above 300°F can potentially cause discoloration.
Can hot pots and pans stain quartz?
No. Quartz resists staining very well, even against prolonged exposure to heat sources. However, dirt and debris under extremely hot pans could potentially cause marks over time.
Conclusion
With proper care and caution around direct high-heat sources, quartz countertops are an incredibly heat-resistant surface choice that can handle all normal cooking tasks. Their thermal performance combined with attractive appearance, durability, and easy maintenance make quartz a top choice for kitchen and bathroom remodels. Following basic precautions, quartz countertops will maintain their smooth, beautiful appearance for years.
