Hello everyone,
Could anybody share some good places to find Limit Formulas, for cone 6
in particular. I do have a number of books, but few contain limit
formulas. I made an Excel Spreadsheet to calculate overall percentages
of chemical compounds in my glazes, and now I need some limit formulas
to compare them to. Thanks a bunch.

Cushing's Handbook 3rd edition seems to be the most quoted.
Unfortunately he misses out cones 03 - 4 inclusive.
I just interpolate between and hope to now obtain a satin glaze at ^01
using 5 parts Borax Frit to 6 parts damp (used) cat litter,
montmorillinite. But of course only experiment in a line test will prove
me right, or WRONG.

Richard Zakin's "Mastering the Craft" has the most complete and
detailed limit formulas I've seen.
