How Much Heat Can Quartz Countertops Withstand?

Quartz countertops are currently among the most sought-after kitchen surfaces, admired not only for their aesthetic appeal but also for their reputation as being more durable and easier to maintain than granite. However, the truth is somewhat nuanced. Despite their robustness, certain precautions must be taken with quartz surfaces. A key consideration is avoiding excessive heat exposure. Although quartz countertops are non-porous and relatively heat-resistant, they do not withstand heat as effectively as soapstone and granite, which are less prone to heat damage. Temperatures as low as 150 degrees Fahrenheit can lead to staining and damage, while exposure to around 300 degrees Fahrenheit may cause warping or cracking.



The discoloration typically arises not from the quartz itself, but from the resin used to bind the quartz slabs, which starts to show damage and discoloration at elevated temperatures. Therefore, it is crucial to protect your quartz countertops from heat by using trivets or hot pads to prevent direct contact with hot items.



Protecting Your Quartz Countertops from Heat

While it may be obvious that placing a pan directly from a 500-degree Fahrenheit oven onto your countertop is a bad idea, you might be surprised to learn that even a hot cup of tea or coffee can cause damage. These drinks are typically heated to around 200 degrees Fahrenheit, which is sufficient to harm your countertop. If heat damage results in discoloration, you might be able to remedy it by gently scrubbing the cooled area with soap and water or a baking soda paste. For more severe issues like cracking, consulting a professional for repair is advisable.

Despite the need for heat protection, quartz counters remain an excellent choice for kitchens. They are significantly less likely to stain than granite and don’t require regular resealing. Moreover, safeguarding your countertops from heat doesn’t detract from their beauty. By choosing trivets, hot pads, and coasters that complement your kitchen’s design, you can maintain both functionality and style. You can even craft your own trivets using old mason jar lids.
