i smiled when i thought of myself, 1960 or so, wanting to make a glaze.
went to leach.
but, i needed water ground quartz.
hell, where do i get that?
oh, is that silica?
and, calcium carbonate?
whiting...used in the paint industry for white paint.
got a bag for a dollar at minnesota paint company.
there was no continental clay...or minnesota clay.
but, there was jack wolf in new york, and they had
copper and cobalt.
when nick brantz opened minnesota clay in his garage, it was
like a miracle.
i was using colmanite at school in about 1969, when i got back
from japan i bought some and it did not work...i missed the announcement.
ruined hundreds of pots. could not figure it out. as most often happens,
we blame our self.

"but, i needed water ground quartz.hell, where do i get that?"
Parenthetically I think that this is where many people get stumped by the
recipe "leach's ^8 clear" which they try at ^9/10 and it looks under-fired.
The US flint air-floated or whatever is not as melty as the finer water
ground stuff
