Anne Wellings directed me to a thread in the archives for slip recipes, and
I found a bunch of blue glazes tested by Tracy Wilson over Cynthia Bringle's
Wet/Dry Bisque Slip at ^6-^10. This one caught my eye:
5.Anderson Blue Sodaspar 53.3 EPK 13.3 Ball Clay 6.7 Whiting 20.0 Cobalt
Carb. 6.7 ______ 100 Matt glaze almost black where thin, army green where
thick. Nice colonial (bluish slate) over white slip >
