I've been lurking on this list for 5 years. Never posted because a) I don't=

My question: I use a lot of lithium carbonate in my sculptural glazes. As=
you know, the stuff is very granular, I'm guessing to decrease inhalation =
risk, and is a bear to work through a sieve. Does anyone see a compelling =
reason why I could not ball mill my lithium into a powder before use? Usin=

The oxide is in carbonate form, so it should be OK to ball mill without solubility problems. I've found that wet ball milling works best, pouring off the result into a five gallon bucket, decanting the extra water once its had a chance to settle, and scooping out the grind into a plaster bat to dry. I do this with Titanium Dioxide and it works well. For the mill that I use, an eight hour grind seems to do the trick for most anything.

Dear James F,
If you are only dealing with kilo or so of Lithium Carbonate I would =
suggest that you either make or procure a 10 inch Mortar and Pestle and =
do this job by hand. Using a rolling action with the pestle rapidly =
reduces granular materials down to a hundred mesh.
Please wear a respirator mask. Breathing Li2C03 fines would be =
inadvisable.
Or recompound your glazes to use Petalite of Spodumene.
Best regards,
Ivor Lewis.

Hi James,
Lithium Carb is the most soluble of the carbonates that we use - grinding
them up in any way will increase the solubility - and may lead to fit
problems.
Why not get a lithium frit and use that?

Hello Ivor,
I have exprienced this type of problem.
I let the glaze sit for 7-10 days to give time
to water to dissolve partly the lithium
carbonate grains, and re-sieve 60 mesh.
