Quartz countertops are a popular choice for many homeowners due to their durability, aesthetic appeal, and ease of maintenance. However, one common question that arises is whether quartz can withstand very hot cookware like pans fresh off the stove. Here is a detailed look at the heat tolerance of quartz and whether you can put hot pans on these countertops.
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 ranges from 90-94%, while the rest consists of polymers and coloring agents.
The resins bind the quartz particles together to form a hard, non-porous surface that is resistant to scratches, stains, and heat. Quartz slabs are manufactured in factories under precise conditions to create the finished countertop material.
Heat Tolerance of Quartz
Most quartz countertops have a high heat tolerance and can withstand temperatures up to 212°F fairly well. This means they can handle hot pans, pots, and dishes fresh from the oven or stove with minimal risk of damage.
However, portions of the countertop near the edges and seams are more vulnerable to damage from extreme heat exposure. Manufacturers often recommend using trivets or hot pads, especially for pans coming directly from the broiler or grill at temperatures above 300°F.
Prolonged contact with very hot cookware could potentially cause quartz to crack, scorch, or discolor over time. But brief contact with hot pans is not typically an issue.
Is It Safe to Put Hot Pans on Quartz?
Yes, you can safely put hot pans on quartz countertops temporarily. Quartz has sufficient heat resistance to handle pans that are moderately hot, such as those used for cooking on the stove or baking in the oven.
As a general rule of thumb:
- Pans fresh from the oven or stove (up to 250°F) are fine for a few minutes.
- Use trivets for extra hot cookware like broiling pans or cast iron (up to 400°F).
- Avoid leaving extremely hot pans from the broiler or grill for prolonged periods.
The material is not as heat sensitive as natural stone, so brief contact with hot pans should not damage properly sealed and cared for quartz countertops. However, prolonged direct heat could cause damage over time.
Tips for Using Hot Pans on Quartz
- Use potholders or trivets when moving cooking pots and pans.
- Don’t let hot cookware sit in one spot for a long time.
- Allow pans to cool slightly before setting them down.
- Clean up spills from hot liquids like coffee immediately.
- Use the backsplash as a resting spot for larger hot pans when possible.
- Avoid subjecting edges and seams to excessive heat.
With some care and sensible precautions, quartz offers excellent durability for busy kitchens. Minor exposure to hot pans and cookware will not affect quartz countertops with proper, manufacturer-recommended sealing and maintenance.
Long-Term Effects of Heat on Quartz
While quartz can withstand temporary heat exposure, long-term effects do need to be considered:
- Discoloration – Sustained high heat can cause quartz to change color, turning darker or lighter over time.
- Cracks – Extreme temperature fluctuations or prolonged heat exposure can cause cracks due to thermal expansion.
- Burn marks – Concentrated high heat from very hot pans placed in one spot can potentially scorch quartz and leave burn marks.
- Loss of shine – Over time, heat can damage quartz’s polished finish, causing it to become dull in appearance.
To avoid potential heat damage, always use trivets for hot cookware and limit direct heat exposure. Also, be sure to have countertops professionally resealed every 1-2 years as recommended.
Is Heat Damage Covered by Warranty?
Quartz countertop warranties vary by manufacturer but often exclude damage from excessive heat or misuse. Thermal shock, cracks, discoloration, and burns caused by very high temperatures would generally not be covered.
However, reputable quartz brands often provide at least a 10-15 year limited warranty against defects in materials and craftsmanship with normal use and care. Be sure to review your specific warranty terms and conditions.
Alternatives for Hot Cookware
If you want to be extra cautious about exposing your quartz to high heat, some alternatives include:
- Cast iron trivets
- Silicon trivets
- Oven mitts
- Pot holders
- Hot pads
- Metal cooling racks
Portable stovetop heat diffuser plates are also an option to help prevent direct contact between extremely hot cookware and countertop surfaces.
The Bottom Line
Quartz countertops have a high threshold for heat exposure, making them very durable for busy kitchens. While they can withstand normal cooking use, it’s still wise to minimize direct contact with extremely hot pans to prevent the possibility of damage over time. With some basic care and precautionary measures, quartz offers an attractive, low maintenance surface that can last for many years.
Frequently Asked Questions
Can you put a hot skillet on quartz?
Yes, quartz can handle the heat from a hot skillet off the stove or oven for a brief period of time. But it’s best to use potholders and give it a few minutes to cool before setting it directly on the counter.
What happens if you leave a hot pan on quartz?
Leaving a very hot pan on the same spot for an extended time could potentially discolor or scorch quartz. It’s best to remove pots and pans after cooking and avoid letting them sit too long while extremely hot.
Can quartz counters withstand heat?
Quartz has a high heat tolerance up to around 212°F. Normal cooking use is fine, but prolonged exposure to extreme heat from appliances like broilers could cause damage over time.
Does quartz burn or stain?
Quartz resists stains very well and does not burn easily. But prolonged heat exposure in one area could potentially stain or scorch the surface. Quick wipe-ups of spills can help prevent any staining or marks.
Can you crack quartz with heat?
Yes, repeated exposure to extreme temperature fluctuations or concentrated high heat could cause quartz countertops to crack due to thermal expansion. But normal cooking use is very unlikely to crack properly installed quartz.
