Clayarters--
Do you have any information as to what effect ball milling a glaze
would have on the overall qualities of the finished glazed pot?... Keep in
mind that we make our own glazes from scratch, and fire to cone 10 in
reduction, and fire many copper-red and cobalt-blue glazed pots.... Best
Wishes .. Marshall

Hi Marshall,
This is a complicated subject - the more you read the better you will
understand the factors involved. Check out the Magic of Fire home page for
a start - http://digitalfire.com/magic/toc.htm
Much of the written material is about BIG mills - I am not sure just how
much reduction goes on in a small mill but you will get very good mixing -
which in itself should lower maturing temperature a little. Over milling
can affect the raw coat as well.

The answer to your question depends on how long you run your ball mill.
Many commercial shops use a ball mill to thoroughly mix their glazes
rather than actually grinding the mix to a uniform consistency. If you
grind to the latter, your glazes will have a uniform color to them, as
in no variation, breaking or specks. Also, depending on what the
"balls" are made from and how long you grind(longer), some of the "ball"
material will end up in the glaze and can change the look of the glaze.
