Quartz countertops are generally considered to be heat resistant, but they are not completely heat-proof. Unlike materials like laminate, which can be damaged by heat, quartz is more heat resistant and can withstand moderately high temperatures without immediate damage. However, it is essential to take precautions and avoid exposing quartz countertops to extreme heat.
Here are some important points to consider regarding the heat resistance of quartz countertops:
Moderate Heat Resistance: Quartz countertops are typically made of about 90-95% crushed natural quartz crystals mixed with resins and pigments. The resins provide some level of heat resistance, making quartz more tolerant to heat compared to materials like laminate or solid surface countertops.
Heat Tolerance Limits: While quartz countertops can handle everyday cooking temperatures and hot pots and pans to some extent, it is recommended to use trivets or hot pads under hot cookware. Sudden and extreme changes in temperature can potentially cause thermal shock, leading to cracks or discoloration on the surface.
Avoid Direct Contact with Heat Sources: Direct contact with very hot items, such as heated pots and pans fresh from the stove or oven, can lead to damage on the surface of quartz countertops. It's best to place a heat-resistant pad or trivet between the hot cookware and the quartz surface to protect it.
Better than Granite: In terms of heat resistance, quartz countertops are generally considered to be better than granite. Granite is a natural stone, and while it is quite heat resistant, it can still suffer from thermal shock when exposed to high temperatures. Additionally, granite can be porous, and if it has not been properly sealed, it may absorb heat and potentially lead to damage over time.
Overall, both quartz and granite are popular choices for kitchen countertops due to their durability, aesthetics, and relatively good heat resistance. However, when it comes to heat resistance, quartz is considered to have a slight advantage over granite. Regardless of the material, it's always best to take precautions and use heat-resistant pads or trivets to protect your countertop investment and keep it looking its best for years to come.
