I like a lot of different glazes, and seem be particularly drawn to rich, dark glazes. However, my usual tenmoku glaze is temperamental. The plum, almost black, glaze that I love may be driven to extinction by poor record keeping. Note to self: Do not assume you will remember which Albany Slip clay substitute you used. Several mugs have been sitting around for some time waiting to be glazed with plum glaze once I figure out the Albany Slip thing. I have a couple of containers of Albany Slip that I made using different recipes. I seem to remember combining these to get the right look for this glaze. Or did I use some of the commercially made stuff? There are a lot of recipes for Albany Slip- apparently no one has found the secret to duplicating the real thing since mining ceased.
pumpkins this year and went with a satin matte glaze instead of shiny. Let's try a spotted pumpkin, too. Speckled clay used here.
