Heh, heh, actually he got a laugh out of that when I explained what 'pot
mill' would mean in English if it was logically constructed after 'ball
mill'. He didn't know why the distinction came into being either, I had
wondered if this was perhaps an older expression in British English or
perhaps a direct translation from another language, such as German? I know
of at least one German who was very inflluential in the Arita area in
improving glaze technology, can't recall his name right now.

What does he do, put 'Pots' in it and let 'em tumble around
a few ten-thousand times?

Hello List,
So, I went to Google, typed in "pot mill" to search, and came up with a
myriad of references. My favorite:
http://www.gootdenki.com/epage1.htm
Click on the Potter's Wheel button and scroll down to where it says
"Electric potter's wheel, TP-5" and read the "Feature:" line.
I could have swooned! This is the wheel for me!
Then scroll further down to "Desk-top electric potter's wheel, RAKURAKU-2"
and read the "Feature:" line again. (WARNING: THIS IS NOT TO BE READ BY
THOSE WHO ARE OVERLY SENSITIVE TO AGE/GENDER BIASED REFERENCES!) &:^D
