Heat Tolerance of Quartz
Quartz counters are designed to withstand moderate heat. The resin binders start to break down at temperatures above 300°F. Most quartz manufacturers recommend avoiding exposing the surface to temperatures above 150°F.
While quartz is more heat resistant than other stones like marble or granite, the prolonged, direct heat from a crockpot on high can surpass its limits.
Potential Damage from Crockpots
The exterior of a crockpot can reach temperatures over 200°F when set to high. Placing a hot crockpot directly on a quartz counter risks:
- Discoloration and burns. The high heat can scorch or discolor the surface. This damage is irreversible.
- Cracks and chips. The abrupt temperature change and concentrated heat can cause the quartz to expand and contract, resulting in cracks or chips.
- Loss of shine. Extreme heat can damage the protective finish, causing dull spots.
- Warping or bubbling. Prolonged exposure to heat can warp quartz and cause bubbles beneath the surface.
Preventing Damage
To avoid ruining your quartz countertops when using a crockpot:
- Use a heat-resistant trivet or hot pad underneath the crockpot. This creates an air buffer to dissipate the heat.
- Don’t pull a hot crock insert directly from the heating element onto the counter. Allow it to cool first.
- Keep the crockpot on a back burner or side counter, not directly on the quartz.
- Set the crockpot to low instead of high, if possible. Low generates gentler heat.
- Check the crockpot’s temperature using an IR thermometer. Don’t let it exceed 150°F on the surface touching the counter.
What to Do if Damage Occurs
If you notice discoloration, burns, or cracks after using a crockpot, stop exposing the area to any heat. Damage may worsen with continued exposure. Light damage can sometimes be sanded out by a professional, but deep burns require replacing the slab.
Take preventative steps like using trivets in the future. Quartz can withstand everyday use but protecting it from extreme, direct heat will prevent permanent damage.
Frequently Asked Questions
Can I put a crockpot on quartz countertop on warm setting?
The warm setting generally stays under 200°F, so it’s safer than high. However, it’s still best to use a hot pad or trivet for prolonged heat exposure. Check the temperature regularly.
What happens if you leave a crockpot on a quartz countertop?
Leaving a hot crockpot directly on quartz can cause discoloration, burns, cracks, bubbles, or loss of shine within one to two hours. Always use a protective buffer between the crockpot and counter.
Is it OK to cut food inside a crockpot on a quartz counter?
No, the friction and scrapes from cutting can damage the quartz surface. Remove the crock and allow food to cool completely before cutting or removing on the countertop.
Can I crack my quartz countertop from a crockpot?
Yes, the intense heat from a crockpot can potentially cause cracks or chips in a quartz counter, especially if there is a pre-existing flaw or weak spot. Always protect the surface from prolonged heat exposure.
What happens if a crockpot boils over on a quartz countertop?
Boilovers can permanently discolor or etch light spots into quartz. Wipe up spills immediately with a soft cloth and avoid abrasive scrubbing. For dried spills, use a razor to lift residue and clean with a quartz-safe cleaner.
Can I repair damaged quartz countertop from crockpot use?
Light damage like discoloration may be sanded out by a pro. Deep burns, bubbles, or cracks usually require replacing the entire affected slab. Prevent future damage by using trivets and monitoring heat.
Conclusion
While durable, quartz counters have limitations when exposed to high, prolonged heat. Always place a hot pad or trivet beneath a crockpot used on quartz, especially on the high setting. Monitor temperatures closely and cleaned spills immediately to prevent permanent damage like discoloration, burns, or cracks in your countertop. With some care, you can safely cook in your crockpot while protecting your investment in beautiful quartz surfaces.
