If you’ve recently invested in quartz countertops, you’re likely enjoying their sleek look, durability, and low maintenance. But you might still wonder: Can I put a hot cup of coffee on quartz?
The short answer is: Yes—but with caution.
Quartz Is Heat Resistant, Not Heat Proof
Quartz countertops are engineered from natural quartz crystals bound together with resin and pigments. This combination creates a surface that’s non-porous, scratch-resistant, and heat resistant to a point. Most quartz surfaces can handle brief exposure to heat up to around 150°F to 175°F (65°C to 80°C). A freshly brewed cup of coffee typically sits between 130°F and 160°F, so in most cases, placing a mug on the countertop won’t cause immediate damage.
However, it’s important to understand that prolonged or repeated exposure to high heat can discolor or damage quartz, especially the resin that binds the surface together.
What Can Happen If You Regularly Put Hot Items on Quartz?
Over time, placing hot cups, pots, or pans directly on quartz can lead to:
-
Thermal shock, which may cause cracks or warping
-
Yellowing or discoloration of the resin in lighter-colored quartz
-
Burn marks or dull spots in the finish
These kinds of damage are usually not covered by warranty and are often irreversible without replacing the damaged section.
How to Protect Your Quartz Countertops
To get the most life out of your investment, consider these simple tips:
-
Use a coaster or trivet under hot mugs, especially if you’re using a French press or pour-over method that involves boiling water
-
Never place hot pots or pans directly on quartz—always use a hot pad or heat-resistant mat
-
Wipe up spills promptly, especially from acidic drinks like coffee or tea, to prevent staining
Final Thoughts – Can I put a hot cup of coffee on quartz?
So, can you put a hot cup of coffee on quartz? Technically yes—but it’s best to make a habit of using a coaster. It’s a small precaution that helps protect your countertops from long-term heat damage and keeps them looking beautiful for years to come.
