These glazes benefit from a heavy-handed application ... except for PCF74 River Birch and PCF Moss Mist, which can both run. Apply fewer or thinner coats near the base of the ware when using these glazes. Stir or shake PCF74 River Birch really well before glazing.

Texture will highlight the beauty of these glazes.
