I finally found my book of glaze recipes. Can't remember where I got
this base glaze. Was trading glazes with my sister-in-law in another
state and her studio uses the same one but with a different feldspar.
29 silica (325 mesh)
20 Kona (sister-in-law uses Custer)
32 Gerstley borate
I can't remember what the base alone looks like.
15% red iron oxide - red/brown - looks great under or over the
3.5% cobalt carbonate - blue breaking purple
0.5% manganese dioxide
15% zircopax - creamy opaque white (less might work just fine
