Sturdy, sophisticated and stunning, granite is one of the many natural stones selected for countertop kitchens. A pink or gray speckled stone, Geology.com explains that granite is an igneous rock, which means it forms as a result of blazing hot magma slowly cooling and crystallizing. Given its sizzling origins, it's fair to wonder if the stone can truly withstand heat. Is it okay to put a hot pan on a granite countertop or is it an accident waiting to happen?
Excavated from stone quarries, The Spruce notes that dense hunks of granite are cut into slender slabs before being polished and transformed into countertops. Since it's naturally sourced, this is often why it has a higher price point in comparison to artificially manufactured stone. Of course, its durability also plays a factor. Cooking Pan Set
Because granite is the byproduct of volcanic activity, Rock Solid Custom Granite reports that its melting point is roughly 2300° Fahrenheit, allowing it to maintain its composure under heat. While granite's reaction to extreme temperatures can be a benefit in the kitchen, does that really make granite heatproof?
There is a difference between being heatproof and being heat resistant. While some swear that granite is totally heatproof, others suggest taking some precautions. The major concern with placing hot items on granite is chipping and cracking. Based on the durable and heat resistant properties of the stone, MSI Surfaces states that this is unlikely to happen, especially if granite has been properly sealed and maintained. But that doesn't mean that you should place cookware directly on granite as you can still risk discoloration.
Since granite is a porous material, heat can be absorbed through the stone, which over time leads to discoloration. Luckily, Arch City Granite & Marble Inc. explains that this staining is likely occurring on the sealant layer rather than the granite itself. Although you can easily gently wash and reseal granite, it's best to avoid the problem entirely by using trivets underneath hot pots and pans.
