Developed by Victor Spinski:
2 #s bentonite
10 #s ball clay OM4
9 #s Sagger XX
27 #s Gold Art
7 #s Custer Spar
5 #s Wollastonite
34-55 #s kyanite
high rag pulp: 15% by volume, or as needed
And, since I just was basically given one, does anyone have any familiarity with an
industrial cast iron Crossely Pug Mill, is rated at one ton/hr. in 4"x8" logs?
Might do wider extrusions as well...for tile? And, since I am asking questions,
where would I find a good source for tile clay bodies, earthenware, and stoneware,
and especially oriented for outdoor freeze/thaw use?
Thanks again to all on the advice with the Hobart Mixer. In reply, I would not use
a Hobart Mixer to mix dry materials... but then again, I would also be cautious in
trying to make a cake liked that , at least one that did not land on the floor. I
would mix the ingredients (paper pulp..has anyone used flour?) into a slip, or very
wet dough like clay. I leaned towards the 20 Qt. mixer in almost new condition
because 4 or 5 gallons of slip/clay would keep me busy. An 80 Qt would be nice, but
I will have to see how the 20 Qt works out. Large Hobart Mixers are expensive, and
the chance of someone virtually giving me one in good working condition seems a bit
remote. I would use a cement mixer to mix dry items, but I would have to put a
cover/bag on it to contain the dust ( hose clamps and plastic). As I see it, from
a dry mix, one can go to either slip mixing and drying for high quality clay, or
to wetting it, and putting it through a pug mill. The suggestion that a Hobart
paired with a pugmill would be ideal, led to a few inquires, and that is how I
ended up with the Crossley Pug Mill, which had to be moved by this weekend.Strange
timing.
Thanks, again
