I like your 'human' quote Vince! Standing ovation to you CME Craft Movement
Era potters (1950 - 1999~) who through extensive trial and error and sheer
hard work built the road upon which we all walk. Last year, someone sent me
a recipe that contained an ingredient I'd never even heard of, and I'm sure
only potter's with old cache stores of ingredients would own. Thus, I am
still interested in starting a wider conversation about keeping the studio
process/supply/repair access going as conditions challenge. [clayart] seems
like an amazing resource to continue *real* information. I am so grateful
for the kind responses to emails from [clayart] people. I wish I'd been
part of the era when you gathered to meet during NCECA; I at least look up
all your websites.  Are other potters also having trouble getting raw
ingredients to make their clay? I've had to switch plans more than once
this year because I couldn't even get the materials to make clay or a
favorite glaze. Continental Clay Co. has been outstanding to help us these
two years, and I've brought in food for the whole crew more than once. With
all the w-o-r-k involved, I find no shame in having a career job and being
a 'hobby' potter because pottery is still significant hours. So much of
pottery has to be love of the craft, and not $ per hour. When art centers
use terms like "Magic Water" and don't give a recipe, I understand that
most won't care or need to know, or that some glazes are part of their
signature look. Are the pottery 'descendants' of Mel, Vince and others
continuing to TEACH "building" a studio and "building" kilns, and "firing"
outside the range the ingredient label specifies? When some core CME
potters 'retire', will others know how to fix anything, fire the kilns or
adjust glazes?
I hope I have thrown out enough bait for more to bite on.
Kindest Regards,
(Restarted pottery after kids, 2019)
