i have a hunch that the ball mill was an aid to old time potters
that had very crude materials to work with. really crude glaze making
materials. they ground it into a usable material.

i am with lee on the grinding of materials beyond their need. it often
takes all the life out of a glaze.

many/most of the glaze making materials are used in industrial applications
like paint/cosmetics/toothpaste. they want the size very small. it
is filtered, milled and ground into a very fine powder. often it is
already well beyond what the average
potter needs.

i sieve out the largest particles, but sure do not go into the
hundreds for screen size.
in fact...i am working on introducing bigger chunks of iron into my glazes.

i break up taconite pellets from the iron mines, and i add iron bearing
sand from the shores of lake superior. i go on mining expeditions every
couple of years. i add to both the clay and the glaze.

in some ways it is a protest to very refined, over the top glazing that
has almost no human/craft aspects. it is becoming like paint, more and
more...not a natural glass surface. i know and respect that glazing is a
personal choice, it is a personal aesthetic, and it becomes often a trend
or pattern nationally. but, some think that milling will give them a surfa=
ce
that is over the top. but, it often has a commercial quality, not an
art/craft quality.

i am not a great exponent of ready made clay, ready made glaze in
50 colors, and then a push button kiln...pre/programmed by someone
else. i like making my clay, glaze and firing in a home made kiln.
it is all mine, good or bad. but, i get the `he's old, he does not
understand.`
well, i do. so, i just do what i do, and get on with it.

if you are going to complain about kmart dishes, pottery barn dishes, well
don't make work that looks just like it.

Why I love making pots . . . although I am far from this ideal.

I have a photograph of a donkey driven grinder for frits from Central =3D
Asia (Uzbekistan where I did my Fulbright research in 1994) . I'll have =3D
to look for it because the photo predates digital.
The potters used the "Horno Arabesque" similar to the ones in Spain, but =
=3D
I had never seen a donkey driving mill before.
The grindstone rotated and there were four drains in the corners of the =3D
base section connected by a large , maybe 6-8" trough.Old time potters =3D
everywhere face similar dilemmas.
