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 worktopsand 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.

I have granite countertops and granite on my island in a new construction. We had a fire in the keeping room / kitchen. We were told that the temperature got to as much as 1200 degrees in the kitchen? Will that hurt the granite and will the granite retain the smoke smell? Thank you. Gail
Hi Gail,
At that temperature there is the possibility of heat fractures. It depends on how the heat was applied. As one part of the granite heats up quicker than another part it will expand slightly quicker which can cause a crack. I would suggest checking the granite very closely and feel to see if there are any cracks. Which granite is it?
I wouldn’t worry about granite holding onto the smell. It’s a big lump of rock at the end of the day.
