Comments:
very nice cream colored glaze.  better over white clay.  tan/brown where thin

This glaze is a good salt liner. Add approximately a tablespoon or two of Epsom salts dissolved in a little warm water to each bucket of glaze to help keep the glaze suspended.
Very nice on stoneware clays, too, in reduction firing (no salt) where it goes a beautiful yellow matte with medium to thin application. Too thick and it goes shiny! Sample picture is on stoneware.
