Hi Dannon,
I also have used the 20/80 GB and Neph. Sy. recipe when I was in school.
Do you have a certain precent for Silver Nitrite that you add?

Thanks and regards,
Alisa in Denmark

The two simplest I know are these:

Gerstley Borate 80=25
Nehpeline Syanite 20=25

and (Piepenburg):

Cornwall Stone 80=25
Nepheline Syanite 20=25

You can add colorants in the form of oxides or stains to
either of these. They both crackle well. In my experience,
Piepenburg's has a more interesting crackle pattern

Cornwall stone will be more expensive than Gerstley Borate.

The materials are available, no doubt, from Mile Hi Ceramics in
Denver.

No, I don't ever use Silver Nitrite. The glazes I mentioned are generally
used in class for white crackle, though sometimes small percents of
copper or cobalt or iron are added.
