Marianne,
Borax is a low temperature flux which helps to melt the engobe. Try using
any frit that you have instead of the borax. Mia in ABQ

In the recipe for white engobe. Can you use Twenty Mule Team Borax for the Borax? You can get that at the grocery store most places. I have my "camp" kids use it for a clear gloss glaze on their pit fired pots, just as it is, but is it any different than "pottery grade" Borax????
