Dear Lee, I agree with you. And I thought that I sort of said so in my =
post. I DO think molecular formulae matter as a reference; I often =
have found they pinpoint the root of a glaze problem more quickly than =
patchkying with the mix. And I agree 100% that formulae work well only =
for highly refined consistent ingredients. To me, the formula road is =
a bit like having a bathroom scale. (erg, phooey). I may think I have =
lost weight and feel I am slimmer, or the opposite, but the scale is =
more objective . Moleculars are only indicators as far as I can tell. =
And as Clayart has discussed a lot, raw materials vary with every batch, =
and sometimes vary considerably, while the theoretical analyses remain. =
So I think testing is the best way, but moleculars are good tool.

I doubt that glazes sold for brushing with be different in little pots =
or gallon cans. It does not make sense that the manufacturer should do =
anything other than concoct a hummungus drumfull and then fill jars =
large and small.

What seems likelier to me is that the little jars dried out quicker and =
the gallon cans content is thinner than what the users "got" in those =
dear little jars. Also they probably wiped their brushes on the rim of =
the dear little jars and cannot do so with the gallon cans.
I suspect it is a matter of glaze consistency, and I would get a =
hydrometer, or make one,. and check.

Also: lots of people try to use glaze like paint. This does not work. =
It needs to be flowed on from a full brush, not "brushed out" like =
paint. Maybe you could give a demo on HOW to apply glaze with a brush. =

LAST: I know wrath will descend on my head. But when you invite people =
to your studio/shop etc. MAKE SURE AHEAD OF TIME that your insurance =
covers this type of commercial traffic.
