Yes, quartzite is heat resistant. As a natural metamorphic rock formed under intense heat and pressure, quartzite can withstand high temperatures without being damaged. This makes it a suitable choice for kitchen countertops, where hot pots and pans are often placed.
Quartzite and granite are both highly heat resistant, but quartzite is generally considered to be more heat resistant than granite. Here’s a comparison of their heat resistance:
Will Quartzite Crack From Heat?
In some cases, Quartzite can crack from heat, but this is rare. Quartzite is highly heat resistant and can generally withstand high temperatures without cracking.
However, like any natural stone, it is not completely impervious to thermal shock. Thermal shock occurs when there is a rapid and extreme change in temperature, which can cause the stone to expand and contract quickly, potentially leading to cracks.
To minimize the risk of cracking due to heat, follow these precautions:
Use Trivets or Hot Pads: Place trivets or hot pads under hot pots, pans, and other heat sources to protect the quartzite surface from direct heat exposure.
Avoid Sudden Temperature Changes: Do not place extremely hot items directly on the cold quartzite surface or vice versa. Allow the stone to acclimate to room temperature gradually.
By taking these precautions, you can help prevent your quartzite countertops from cracking due to heat and maintain their durability and beauty.
Can You Put Hot Pans Directly on Quartzite Countertops?
While quartzite countertops are highly heat resistant and can withstand the heat from hot pans without cracking or getting damaged, placing hot pans directly on the surface is not recommended. The quartzite itself will be fine, but the sealer applied to protect the stone can be damaged by high temperatures.
The sealer is designed to shield the quartzite from stains and moisture, but high heat can degrade or discolor it, reducing its effectiveness and potentially requiring reapplication sooner than expected. To maintain the integrity and appearance of your quartzite countertops, always use trivets or hot pads under hot pans and cookware to protect the sealer from heat damage.
Is Quartzite More Heat Resistant Than Granite?
Yes, quartzite is more heat resistant than granite, however, this is a small difference in the two stones. Keep reading to get the full picture.
Quartzite:
Quartzite is formed from sandstone that undergoes intense heat and pressure, making it extremely hard and durable.
It can withstand very high temperatures without being damaged, making it one of the most heat-resistant natural stones available.
Granite:
Granite is also a natural stone formed under high heat and pressure, and it is known for its durability and heat resistance.
While granite is highly heat resistant, it is slightly less heat resistant than quartzite due to its mineral composition.
Practical Considerations:
Both quartzite and granite can handle the heat from hot pots and pans, making them excellent choices for kitchen countertops.
Regardless of the stone, using trivets or hot pads is recommended to protect the surface and prolong the life of the sealant.
While both materials are suitable for high-heat environments, quartzite generally offers superior heat resistance compared to granite.
Takeaway
Quartzite is highly heat resistant, making it an excellent choice for kitchen countertops, but it’s important to use trivets or hot pads under hot pans to protect the sealer from damage. While quartzite itself can withstand high temperatures without cracking, the sealer used to protect the stone can degrade or discolor if exposed to direct heat.
