Baking Clay Tiles: Set a kiln or an oven at a temperature range usually preferred for household baking purposes. Usually, polymer_clay manufactures mention the required temperature range as a part of the packaged instructions. Bake the clay tiles in the oven/kiln until their upper surface develops a distinct crust.
STEP 7: Cleaning and sealing __ Make sure you sponge off the residue on the surface of the tiles before it has the chance to dry. This step will require several passes over a period of an hour or more. It's a critical stage when you're working with tiles that have a porous or variegated surface. Dried grout can prove almost impossible to remove from indentations.
