Usually if a clear turns milky because the glaze is to heavy, clear should be applied thinly, the color and the chemical composition of your clay can also affect a clear glaze. I tested over 100 clear formulas trying to find one that would stay clear and not be altered by my red calico clay body, never found it. At cone 6 the glaze tile would either be milky, greenish or dark brown, I wanted it to stay a warm toasty red, I finally gave up and used Nutmeg glaze. As far as rescuing the piece you could try reglazing it with a another glaze. Denice Wichita, KS Link to comment Share on other sites More sharing options...
Guest HerbNorris Posted July 2, 2011 Report Share Posted July 2, 2011 I agree with Denice, your glaze was probably too thick. My clear glaze is suprisingly thin, almost like plain water; when I first started to fire it, it was coming out milky, then I thinned it out and now it's nice and clear. Depending on how it was applied, and the shape of the piece, a re-fire might fix it. What do you have to lose? Link to comment Share on other sites More sharing options...
