How to Age Vintage Keystone Canonsburg Pottery
Results can be unpredictable, so experiment with one piece at a time until you achieve the desired result.
-
Wash each piece thoroughly in a mixture of liquid detergent and water. Any oil residue, even from your fingers, can prevent the glaze from sticking. Wear rubber gloves when drying the piece. Dry thoroughly.
-
Heat each piece in the microwave or oven.
-
Spray the piece with a sticky hairspray or brush on glue. This will be the base needed to make the glaze stick to the glaze that is already on the plate. Let dry thoroughly.
-
Mix wood stain or acrylic paint with glaze. Use one part stain or paint to two parts glaze. Sponge onto the plate over the base coat of glue or spray. Let dry thoroughly.
-
Fire the piece in a kiln and let it cool overnight.
