Inthe Good Grey Celedon and the Jade I used cobalt carbonate and
the glazes are from George Lowe in a collection of
formulas I got from Anderson Ranch.
The Good Grey is blue on porcelain and a great glaze.
It uses such a miniscule amount of cobalt that it is like
a dusting...It's a kick to measure .007 grams of cobalt.
happy glazing
