How do you Answered
I was just wondering if anyone out there knew how to seal stone in such a way as to make it useful as a food service platter or maybe a cup. I know its possible to use glaze like one would on a piece of pottery (or maybe tile sealant?) but I would like to find some way that 1)doesn't require a kiln and 2) leaves the rock looking like regular rock. Best would be a way that makes the rock look wet but matte and doesn't change the texture. I was thinking something similar to what is used to seal wooden cups but I haven't been able to figure out what is used.
