Quartz vs. Granite: Heat Resistance & Other Properties

Couple cooking on a granite top.

Your kitchen countertops take a lot of heat – both literally and figuratively. Hot pots and pans, dishes and mug bottoms are all usual suspects on a typical day. So, when comparing countertop materials, you want to find something that can stand up to a range of temperatures and the general hustle and bustle of an active kitchen. Today, we’ll look at the properties of two of the most popular countertop materials: quartz vs. granite heat resistance and more.

Quartz vs. Granite: What They’re Made of 

Before we break down quartz vs. granite heat resistance capabilities and other characteristics to consider when deciding between these two materials, let’s first establish the basic composition of each. 

Quartz is an engineered stone made from a blend of pulverized stones like granite, natural raw quartz and industrial waste products such as glass, all held together by polymers and resin binders. Meanwhile, granite is a naturally occurring stone that’s created as magma crystallizes deep underground. Featured minerals in its composition include feldspar, mica and quartz. 

Quartz vs. Granite: Heat Resistance & Other Properties

Now, let’s investigate how these differences in composition influence the properties of each material respectively:

  • Heat resistance – When it comes to quartz vs. granite heat resistance, granite decidedly wins out. The process by which it originates lends granite nearly unparalleled density, making it incredibly durable. Its hardness also enables granite to tolerate heat, along with other elements of a busy cooking space, quite well. Quartz is also very strong, but it can crack or sustain other damage if hot cookware is placed directly atop it. This is because the resin that binds quartz together may melt or warp.
  • Sealing requirements – Whether a countertop requires sealing depends on its porosity. Quartz has a leg up on granite here, as it is nonporous and thus doesn’t need sealant to guard against bacteria and liquid intrusion into the surface. Many types of granite, on the other hand, will need to be sealed to keep them hygienic and prevent stains and other damage, as is the case with most natural stone surfaces.
  • General maintenance – Both quartz and granite are relatively easy to take care of from day to day. Simply wipe down countertops as needed with a soft cloth or sponge and a mild cleaner. (For granite, double-check that your chosen cleaning solution is approved for use on natural stone.) With either material, it’s best practice to wipe up spills promptly. And, just to be safe, it’s always a good idea to use trivets and coasters to prevent marks and protect against damage, even though granite is heat resistant.
  • Applications – Quartz can be damaged by exposure to direct sunlight over time, so it’s best limited to indoor spaces that don’t get overly sunny. Granite, however, can stand up to the elements without issue. Thus, it can work in a wider range of settings, including in outdoor kitchens.

Ultimately, the choice between quartz vs. granite hinges on the particular qualities you most prioritize in your new surface. If you’re looking for a heat-resistant and overall resilient material and you don’t mind keeping up with sealing your countertop or other surface, granite may be your best bet. If you wish to skip sealing but still seek a hardwearing surface that offers plenty of benefits, quartz may be preferable.
