TECO GREEN - A Tom Zwierlein matte glaze based on a Val Cushing recipe.Reminiscent of the green to grey glaze found on American Art Pottery known as Tecoesque.Really greys out to an ugly color on white stoneware if applied too thick but holds it’s own on other clay bodies [from tans to reds to browns] producing different, interesting effects.

METALLIC GREEN - This metallic luster glaze looks awesome on clays with iron - Laguna’s Electric Brown, Hawaiian and Standard’s 266 Brown or over engobes or stains made from red iron oxide.Both the Sky Blue and Ocean variations also produce metallic lusters and look best on iron rich clays, stains and engobes. Three brushed-on coats really cover well; if more translucency is desired, one heavy or two lighter coats do the trick.

  2. Yes, thanks bucket loads for sharing these wonderful recipes. I do have one question which I should know the answer to; but, alas, I'm clueless as to what you mean by "brushing medium". Is this something that you add to the glaze if you plan to brush it onto your pot?

  3. CmC gum, the bentonite also helps -- it keeps everything in suspension, makes the glaze honey-like -- check how to mix the CMC gum, nifty stuff
