  1. I can assume you are using this as a decorative effect and not as an eating surface. I would not call that a true glaze. I have a glaze I use that you could play around with. It is a metallic black but if you experiment with changing the manganese and cooper content it might work.

    Metallic Black Matte ^6

    Dolomite –---------------- 6

    Zinc Oxide –-------------- 9

    Whiting ------------------- 9

    EPK –---------------------- 11

    Strontium Carbonate ---- 20

    G200 Feldspar ----------- 45


    Copper Carbonate –------ 4%

    Manganese Carbonate --- 8%

  2. Soy wax sounds good. If you see to burn candles in the home than I see no problem in the studio. I don't like the wax resist stuff and I believe the fumes may be worse than candle wax in the firing. Temperature is key to good adherence. Hot, but don't let it burn. It works best on bisque ware.

    I mostly use a large rectangle of one inch foam that I soak in water first than squeeze out a bit and lie down on a table. Then, after I dip each pot, I slide it across the foam and that usually takes care of it. I mainly glaze green ware.
