Besides its stunning, long-lasting beauty, one of the top advantages of granite countertops is their durability. In fact, granite is one of the hardest materials on Earth. Natural stone is resistant to scratches, stains, and heat. One of the most common questions homeowners ask is: Can granite countertops burn?Granite Countertop - Can they burn?
The simple answer is that no, granite as a natural porous stone will not burn, Because it began as a liquid magma deep within the Earth, and over millions of years is cooled and compressed, it has a natural resistance to heat damage.
Unlike other natural or synthetic products that require trivets to avoid marring their surface from hot pots and pans, heat does not damage these counters. Pots and pans heated to 900 degrees will not scorch its lustrous finish, and even a direct flame applied to its surface will not leave burnt or scarred marks.
However, the long answer is that, while it is generally safe to briefly set hot cookware directly on top of your countertops, there are considerations that may make use of a trivet or hot pad wise.
Epoxy Resin Sealants
If your slab has been treated with epoxy resin sealants, the epoxy may soften with exposure to high temperatures. However, according to Stone World, small cracks and fractures will not be affected, and any visible patches of epoxy glue will soon revert to their original state once the surface temperature cools.
If you have applied a topical sealer to your counters, check the product label for any warnings about interactions with heat and possible damage to the finish. Some sealants, especially those with a wax base, may burn and become difficult to remove.
Granite, especially darker varieties, retains heat. Placing a flame-hot pan directly onto a counter will heat the surface. If someone touches this spot immediately after the pan is moved, there is a risk of injury from burns. Because the stone's color does not change when extremely hot, there is no warning that the surface could be potentially dangerous.
Placing a hot pan directly onto an improperly sealed countertop can result in oily stains if the bottom surface of the pan is dirty. While the pan may look clean to the naked eye, metals in the pan may react with the burner, causing a residue that may stain.
While a granite countertop will withstand hot cookware, it is smart to allow pots and pans to cool before placing them on the surface. When heat is applied to a cold surface, the rapid shift in molecules can cause cracks, and over time may compromise your counter’s integrity.
Always check with your fabricator in order to avoid damaging the granite. To be on the safe side, consider using trivets and hot pads to absorb heat, prevent stains and protect your investment.
