Default Using Limestone for oven floor

My friend has a granite shop and has a piece of Grayish Limestone he had left over from a countertop 1 1/4" thickness and 4ftx4ft. I can have him cut to specs, but want to know if using this as the surface and using insulating firebricks underneath would be good enough without issues. Do I need to treat the limestone in any way?

thanks in adance

You need to not use it for the floor of your oven.

The crystal structure of limestone isn't stable under the heat that WFOs get into. You'll be fighting it falling apart in short order.

Sorry.

Thumbs up Re: Using Limestone for oven floor

Limestone, wherever you incoorporate it, is going to wear easily and produce a powdery surface with use....unless it has turned to dolomitic limestone, which is a bit harder.

While soapstone does absorb and hold heat well, the reviews are mixed on soapstone on the oven floor. Here (Soapstone vs Firebrick ??) is a good informational link on the subject. Keep searching, your friend will have something you need

Yes, you can give any shape to limestone tiles because these are flexible. You can use limestone tiles on flooring, countertops and walls.
