where can i get an 18" stone

i have a friend who is designing a oven and he needs a deck stone i use conveyors and don’t know where to get one

thanks for the help

I order mine from a monument company that makes headstones

Stones of most sizes can Purchased from a place called,I think, the oven deck shop.
I will post the address and phone number when I get back to my office monday.
