I don't know much about ball mills but my husband has some knowledge of stainless. He said to stay away from them, the stainless surface will wear away add small amounts chromium and iron and many other metals to what ever your grinding. I hope someone with more experience with ball mills can give you a better answer. Denice
geez, its only been 18months. first we got the mill going then I found a porcelain jar hidden in the center of Portugal. Bailey ceramics sells porcelain balls, 1/2 inch in diameter. for a 1.5 liter jar I apparently need 3 pounds of porcelain balls. Well to have that shipped from th USA is a bit pricey. So I inquired here in Portugal and they only have stainless steel balls. Is that OK to use in a porcelain ball mill jar?

I have some that came with my used ball mill that were home made. Just fire them to the maturity temperature of the porcelain.
Some can be round . The commercial ones are barrel shaped and have rounded edges. You could extrude 1/2" coils and cut them to 5/8" lengths and smooth the edges.

The cylindrical forms provide a better surface contact for grinding but the balls will work ..if they are fired hard enough.
Looking forward to visiting the Atelier in the future.
