How heat resistant are granite worktops

I often get asked this question. In reality nothing is completely heat proof, heat it enough and it will react. Granite is no different, after all it was originally formed from super heated magma being pushed up through the earths crust.

What about your kitchen? Well I should say never put anything hot on your granite worktops and then we are completely covered but that is a bit like saying 'may contain nuts' on a packet of peanuts. Granite is very very heat resistant and it it very unlikely to meet the extreme temperatures that would be needed to damage them in the average family kitchen. I have had granite worktops at home for many years and I put pots straight off the hob and trays straight out of the oven on the worktop, and yes I do do the majority of the cooking at home. In the fifteen years I have been in the stone industry

I know of only one instance when a granite worktop was damaged by heat and that was when someone lit a disposable barbecue directly on the worktop and left it on there for a few hours and it cracked the granite. Lets be honesty thought, that was a bit stupid!

So the short answer to the question is don't worry about putting hot things on your beautiful new and shiny granite worktops.
