Quartz countertops are popular choices for many kitchen and bathroom remodels due to their durability, aesthetics, and low maintenance. However, some homeowners wonder – can quartz countertops burn? The short answer is yes, quartz can burn under extreme heat exposure. However, quartz is more resistant to burns than many other countertop materials. Here is an in-depth look at how heat affects quartz and steps you can take to prevent burns.
What is Quartz?
Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The quartz content typically ranges from 90-94%. The remaining 6-10% consists of polymers and dye.
The resins bind the quartz particles together to form a durable, non-porous surface. Quartz slabs are fabricated in a factory and shipped to installers. Compared to natural stone, quartz offers a consistent color and pattern. It’s also non-porous, making it stain and scratch-resistant.
Can Quartz Withstand Heat?
In general, quartz is more heat resistant than solid surface materials like Corian. Quartz can withstand brief exposure to temperatures up to 300 degrees Fahrenheit before potential damage occurs. By comparison, Corian counters can incur damage when exposed to temperatures above 150 degrees.
However, compared to some natural stones, such as granite, quartz has lower heat tolerance. Granite can withstand temperatures up to 500-600 degrees before burning.
So while quartz has reasonably good heat resistance, it’s not invincible against burns from hot cookware or other heat sources. Extended direct heat exposure can damage quartz.
How Heat Burns Quartz
When quartz overheats, two types of damage can occur:
Discoloration
Pigments and resins in the quartz can burn, causing discolored spots or rings. These burn marks result from temperatures exceeding 300 degrees.
Cracks/Chips
The resins binding the quartz together soften under extreme heat. As they liquefy, the quartz surface loses integrity and may crack or chip. This type of damage requires temperatures above 300 degrees.
Hot cookware, such as pans coming straight from the stovetop or burner, can sear these burn marks and damage into quartz. Areas near cooking surfaces are most susceptible.
Preventing Burns on Quartz Countertops
While quartz can withstand brief heat exposure, you’ll need to take some precautions in your kitchen. Follow these tips to prevent damaging your quartz counters:
- Use trivets and hot pads when placing hot pots, pans, bakeware, etc. on your counters. This includes cookware coming straight from the oven or stove.
- Don’t leave appliances that generate heat, like crockpots, griddles, or instant pots, directly on your counters. Use protective mats or trivets.
- When using your counters for food prep, use cutting boards. Avoid cutting directly on the quartz surface.
- Don’t place burning hot plates or dishes straight from the microwave on unprotected quartz.
- If you have an electric stove, take care when reaching across the cooktop. Bare arms can get burned. An insulating cover around the cooktop perimeter is advisable.
- Take care with hair styling tools. Don’t place extremely hot irons or curling wands directly on quartz surfaces.
- Install a backsplash to protect the wall counter joint from accidental burns.
With some care and precaution, it’s possible to keep quartz counters burn and damage-free. Small routine spills aren’t a concern, but be vigilant about direct high-heat exposure from appliances and cookware. Quartz can withstand brief contact, but extended exposure at extreme temperatures will cause burns. Trivets and cutting boards are a cook’s best friends where quartz counters are concerned.
Frequently Asked Questions
Can hot pans permanently damage quartz?
Yes, placing very hot pans directly on quartz can potentially cause permanent burn marks and discoloration. Always use trivets or hot pads with cookware coming straight from the stove or oven.
What temperature can quartz withstand?
Briefly, around 300 degrees Fahrenheit. Prolonged exposure above this can risk burns and damage. Quartz has moderately high heat tolerance but is not invincible.
Is it OK to cut on quartz countertops?
It’s best to use a cutting board instead of cutting directly on quartz. The cutting action can gradually dull the surface over time. A board will keep your counters pristine.
Can you put a hot crockpot on a quartz countertop?
No, the prolonged direct heat from a crockpot can damage quartz. Always use a trivet underneath to prevent discoloration or cracks.
Is quartz more heat resistant than Corian?
Yes. Quartz can withstand temperatures up to 300 degrees F. Corian begins incurring damage around 150 degrees, making it more prone to burns.
Conclusion
Quartz offers many advantages for busy kitchens, including durability, stain resistance, and easy maintenance. While quartz can withstand brief exposure to moderate heat, direct high temperatures from cookware, appliances, and other sources can cause permanent damage over time. With some simple precautions, it’s easy to keep quartz counters looking like new. Strategic use of trivets, hot pads, and cutting boards will prevent damaging burns. While quartz is resilient compared to other materials, its heat tolerance has limits. With prudent use, quartz counters can remain in pristine condition for many years of cooking and entertaining.
