Can granite countertops burn or scorch?
No. Granite cannot be burned or scorched with ordinary use. Granite is formed by extreme heat and pressure so it cannot be affected by cooking temperatures. A lit flame placed under the granite will have no melting or scorching effect. You can take a pot of boiling water directly off of the stove or a pan directly out of a 500 degree oven and put it on top of the granite without worrying about leaving any marks. Most cooking takes place at 250 degrees or higher. With that in mind consider the following:
Corian is reported to be able to withstand temperatures up to 212 degrees. When a flame is placed under Corian it will ignite. The manufacturer recommends running cold water anytime you pour boiling water in the sink (straining pasta, potatoes etc.) to avoid warping the sink.
Engineered stones (Silestone, Ceasarstone, Zodiac, Cambria etc.) claim to be extremely heat resistant because they can withstand temperatures up to 225 degrees. The manufacturers of these products tell you not to place hot pots and pans directly on them, especially for long periods of time, since doing so can scorch or warp the material.
Granite is reported to be able to withstand temperatures between 1200 and 1650 degrees. Hot pots and pans can be taken directly from the oven or stove and placed on top of the granite without fear of scorching, burning or warping. You can use crock pots, electric griddles, coffee makers, waffle irons etc. without marking the granite in any way.
