Taking good care of your pretty granite countertops helps determine your actions in the kitchen. To preserve the look of the stone, home owners are sometimes afraid to set a hot pot or hot pan onto the surface of a granite counter for fear it will burn the stone, but this worry is unfounded. Granite is formed under intense heat, and can withstand a good deal of heat long after it is in your home.
In the shop, when granite slabs are being fabricated and formed into your counters, the blade cuts best if combined with running water. However, once the cut, the glue can only adhere to completely dry stone. In order to speed up the drying process, a flame torch is commonly turned onto the stone in order to dry every drop of water from the granite.
If a flame thrower does not injure the natural beauty of your stone, a hot pan can't really do any damage either!
The only situation that a flame torch might not be used to dry the water from a slab is when the slab is an engineered stone, also known as quartz. Companies that produce quartz slabs are Caesarstone, LG, Silestone, Cambria, Dal, etc. These slab surfaces are a combination of real granite and polymer glues, and the glues are the substances susceptible to burns. Because of this, quartz companies such as Cambria recommend a hot pad be placed between countertop and hot pans and crockpots.

The last instance where we have seen heat impact granite involved a black stone countertop that was exposed to direct California sun. A single slab of absolute black granite countertop covered the cabinets inside the kitchen, continued underneath a large window, and formed an outdoor bartop as well. The difference in temperature between the controlled household air and the open outdoors air, combined with a black surface absorbing the daily sun, caused the countertop to crack in many places. This situation was isolated, however, and does not represent a common occurrence in kitchens.
