Quartz countertops are popular in many modern kitchens due to their durability, appearance, and low maintenance. However, their heat resistance has limits. Setting a very hot pot directly on the surface can potentially damage quartz. With some care and common sense, you can use a hot pot safely on a quartz countertop. Here is what you need to know.
What Temperature Can Quartz Withstand?
Quartz countertops are engineered stone made from crushed quartz combined with resins and pigments. This material is quite heat-resistant:
- Quartz can withstand temperatures up to 300°F for brief periods.
- Prolonged heat exposure above 150°F can cause damage.
So quartz can tolerate briefly setting down a pot or pan fresh from the stovetop or oven. But consistent exposure to very high heat can scorch, discolor, or crack the surface over time.
Is a Hot Pot Okay for a Short Time?
Brief contact with a hot pot or pan is fine for a quartz countertop. For example, quickly setting a boiling pot of water on the surface to drain pasta will not harm the quartz.
However, letting a very hot pot or any heated cookware sit directly on the quartz for an extended time can be problematic. The sustained heat can damage the resin binders in the stone.
As a general rule, any cookware hotter than 150°F should not remain on quartz for more than a few minutes.
How to Use a Hot Pot Safely
To avoid accidentally damaging your quartz, take these precautions when using hot cookware:
- Use trivets or hot pads – Place trivets, hot pads, or folded towels under hot pots and pans to prevent direct contact with the stone.
- Don’t let it sit – After briefly setting a hot pot on quartz, pick it back up promptly. Don’t let it sit and transfer heat for an extended time.
- Give it space – Don’t crowd multiple hot pots close together on the countertop. The combined heat can be damaging.
- Avoid extremes – Don’t put anything extremely hot, like a cast iron pan fresh from a 500°F oven, directly on quartz.
- No hot pads – Don’t place hot pads or trivets directly on quartz when still hot from the oven. Allow them to fully cool first.
What About Electric Hot Pots?
Small electric hot pots, sometimes called personal cookers, reach simmering temperatures to cook foods like soups or oatmeal. Can these be safely used on quartz?
The answer is maybe, with caution. Since electric hot pots are meant to be stationary, the sustained heat on one small spot can potentially damage quartz over time. However, you can take some steps to reduce the risk:
- Place the hot pot on a trivet, especially when simmering.
- Periodically move the hot pot to distribute the heat impact.
- Make sure the hot pot base is smooth and flat. Jagged edges concentrate heat.
- Avoid cranking the hot pot to highest heat settings for prolonged periods.
What to Do If Quartz Is Damaged
If you do notice discoloration or a burned spot from a hot pot, don’t panic. Light damage can often be sanded and polished out by a professional. For deeper damage, the affected section of quartz may need replacing.
Be aware that excessive heat damage may void any warranties on your countertop. Be sure to follow the heat guidelines from the manufacturer.
The Bottom Line
Quartz countertops can withstand moderate heat, but consistent exposure to high temperatures from hot pots and other cookware can damage the surface. Follow common sense precautions, use trivets, and avoid leaving simmering pots sitting for extended periods. With some simple care, your beautiful quartz countertop can stay looking pristine.
Frequently Asked Questions
Can I put a hot pot directly on quartz?
It’s best not to put a very hot pot, especially one boiling or simmering, directly on quartz. Use a trivet or hot pads under hot cookware to prevent direct contact with the stone.
What happens if a hot pot sits on quartz too long?
Letting a hot pot sit on the quartz for an extended time allows concentrated heat to potentially damage the resin binders in the stone, resulting in discoloration or cracks.
Is it OK to cook or simmer food in a pot on quartz?
No, you should not cook or simmer food directly on the countertop. The sustained heat in one spot could damage the quartz over time. Use the stovetop or oven for cooking.
Can I put my electric hot pot on quartz?
You can place an electric hot pot on quartz but use caution. Put it on a trivet, periodically reposition it, and avoid excessive heat settings for long periods. The concentrated heat may damage the surface.
What temperature can quartz withstand?
Brief contact up to 300°F is fine, but prolonged heat above 150°F is not recommended and can damage quartz over time.
How can I fix damage from a hot pot on quartz?
Light heat damage may be repairable by sanding and polishing the area. Deep damage may require replacing that section of the countertop. Follow up with your countertop provider.
