Granite myths and truths - Part 1

The following is taken from an article by Jim Heaphy in Kitchen & Bath Design News

We’d like to shed some light on common myths and misconceptions about granite countertops. Some of these myths are spread by people trying to sell granite, or people trying to sell competing products by criticizing granite.
Myths also originate when people try to simplify complex matters, coming up with generalizations that are true much of the time but not all of the time.

MYTH BUSTING
Over the next few days we will look at some of the most common myths about granite:

“Granite is heat resistant, so it is perfectly okay to place hot pots on a granite countertop.” While it’s true that granite is quite resistant to the sorts of temperatures encountered in kitchens, excessive heat can damage or discolor some types of granite sealers. Rapid heating can also generate internal stresses that could cause a crack at a weak spot, such as a natural flaw or fissure in the stone. An easy way to eliminate potential problems is by using a trivet with feet.
