FAQ Friday : Granite and Heat Resistance

A frequently asked question we get is:

Can I place a hot pot directly onto my granite countertop?

Here’s what we tell our customers:

Every once in a while, your granite countertop will be able to handle a dish taken directly out of a hot oven, but repeated exposure to high temperatures can eventually lead to discoloration of the stone or sealer or gouges in an extreme scenario. Granite is one of the most durable countertop materials you could choose for your workspace.

A major factor is a difference in temperature between the hot item and the cold surface of the granite countertop. The average house sits around 73 degrees Fahrenheit versus a pan out of the oven is generally going to be 350-500 degrees. This quick temperature shift of the counter can cause shock, which can cause cracks and/or chipping.

The best way to avoid damaging the surface of your granite kitchen countertop is to appreciate its durability – not take advantage of it. In other words, appreciate the fact that an occasional oversight will not harm the countertop. But do not assume that constant abuse will be forgiven, avoid placing hot pots or pans directly onto the surface when= possible. Have a trivet accessible when cooking to act as a barrier between hot pots and granite countertops.

Besides protecting your investment of new granite countertops, there are also several other reasons why Granite and Marble Creations recommends using hot plates or trivets. Hot pots or pans may take off the protective coat of sealant from the surface, especially with continued exposure, making your countertop vulnerable to future stains. Your granite will also pull heat away from things, such as a hot casserole dish, causing the dish and food to cool more quickly.
