Hi

Anyone ever tried engraving ceramic tiles?

I have just engraved a pattern on a glazed ceramic tile on a CNC machine with a diamind drag bit, should the surface be sealed and if so, what should be used.

The one I have done will be used as a trivet, but I would like to create some more for the sink in the outhouse so they need to be waterproof
