Duncan took a clear glaze (pink) off the market for dipping bisque ware because the EPA wanted them to verify that ceramicists were firing at a cone 06 so the lead in it was safe. Â I hand-paint my work with a vey high dimensional effect and the new glazes on the market make it flatten and spread out a ton. Not a good thing. I was hoping someone out there might know of a product or glaze recipe. I appreciate any help!
