Stone is heat resistant, nothing is heat proof. Below we will educate you about heat and the effects it has on the different surfaces of stone that we offer.
Thermal Shock: Do not place a hot pot on your countertop, move it, then place a cold item in the same spot immediately after (or vice versa). This will create thermal shock and potentially crack the stone.
GRANITE
Granite countertops will not melt or blister when exposed to heat. They are one of the most heat-resistant countertops on the market. If you take a hot pan out of the oven, you can place it directly on your countertop surface without any harm. Experts do recommend the use of a trivet when using appliances that emit heat for long periods of time, such as crockpots. Since the material is so dense, there is a small possibility heating one area of the top and not the entire thing, could cause the countertop to crack. (From UNS Resource / March 17, 2017)
QUARTZ
Quartz is made of +/-93% natural quartz and +/-7% epoxy resin, binders, colorings, etc. This 7% is the part that can get damaged by heat. Though quartz countertops are heat resistant, it can burn due to extreme heat or prolonged exposure to heat. We highly recommend using a trivet when placing something hot on the surface of quartz. Though burning is rare, if it happens, there is no fixing it.
MARBLE
Marble has the same heat resistant properties as granite – See above.
SOAPSTONE
Soapstone has the same heat resistant properties as granite – See above. The only difference is soapstone takes longer to cool down once the heat source has been removed.
