longevity and consistency of glaze ingredients

Hello,

In preparing to make glazes, I'm gathering my ingredients, and
recognize the economic and consistency benefits of buying large
quantities of some ingredients.

My question is for which ingredients or type(s) is it most important
to buy 50# bags (or more), and which ones or type(s) should I not
combine batches.

Compounding the complexity of my situation are the twenty buckets of
indeterminate age, some nearly full, some nearly empty, of some
common ingredients: boron frits (3124, 3134, 3195), clays, fluxes
(neph sy,talc, whiting, wollastonite, feldspar, etc.), and opacifiers
(bentonite, superpax).

I guess it would be important for consistency in colorant oxides, but
what about the rest?

For now I'll be concentrating on cone 6 oxidation recipes, and will
be using mostly those recipes and techniques in MC6G as a starting
point.

Thanks.

Regards,
Maurice
