If granules are too large... add water.
If granules are too small... add PEG
I started with a 30% volume suspension. This means 30 cc of ceramics for 70 cc of water.
To convert from volume to density for the ceramic materials… 30 cc * 2.6 g/cc (average density of powders) = 78 grams of ceramic powder needed.
I screened the material from the main jar. After passing through a 200 mesh screen, the result was a super-compact, fine powder that doesn't clump.
Below are a few images I took of the process. Also, I just put up a short video here...
