Are quartz countertops heatproof?

The answer is yes, and no. Quartz countertops can take a beating. However, they are not indestructible and can suffer if you put pots and pans over 300° on the counter. Why is that?

Quartz countertops have a composition of 94% quartz and 6% polymer resins. The polymer resins protect the stone from staining and make it easier to maintain over time.

The polymer resins make it more durable than granite or marble. Unlike those stones, you do not need to reseal your quartz countertop every year.

However, it also has a lower heat threshold than a granite countertop. The low heat resistance is due to the polymer resin, which only has a 150° threshold. As we mentioned above, the quartz stone has a 300° threshold. Since the polymer is like glue, it is not surprising that the resin burns at a lower temperature than the surrounding quartz slab.

The low threshold makes it more likely to burn or break when in contact with heat. Therefore, you can put a hot mug of coffee on your countertop, but a searing hot pan or boiling pot of water could leave a burn mark.

Over time, coffee mugs and teacups could leave burn marks as well.

Alternatively, as we discussed above, it could lead to a potential crack in the quartz due to the heat or rapid change in temperature.

Protect your quartz countertops from heat

#1. Use Trivets and Hot Pads

When you are cooking, do not place hot pots and pans right on your counter. Instead, put them on trivets and hot pads. Both use a treatment, which is why they can resist higher temperatures than your quartz countertop.

It is a natural fix that you can use on a regular basis that will save your quartz countertop from excessive heat.

#2. Don’t forget Coasters

While most coffee and tea mugs will not burn through your quartz counter the first time you set them down, you do not want to tempt fate. Use coasters to protect the stone from heat marks.

Over time this will help you with the maintenance of your counter.

#3. Use the finest materials

All quartz use similar construction methods. The difference is the materials and providers who deliver your quartz stone. Do they have the quality quartz stone that can help you stop burns and heat exposure from getting worse? It is essential to know what ingredients manufacturers use to make your granite countertop.

What to do if your quartz countertop has a discoloration?

We want to tell you it is okay if you see a discolored countertop. However, the truth is that removing discoloration from quartz is not always possible.

While you can fix the discoloration in marble or granite easily, quartz is a different matter. The best you can do is hide the stain and hope no one notices.  

Or if it is bad enough, you might want to consider replacing a section or your entire countertop.

Final Thoughts

The question “Are quartz countertops heatproof” doesn’t have a definite answer.
