Anyone ever used a cobalt carbonate that specifies it's 46% on the MSDS?
I ordered a "good deal" on some cobalt carb and can't say I've ever seen it as 46% on the data sheet (usually it says 100%). Molecular formula is the normal CoCO3 I'm used to seeing.
Not seeing anything on any of the paperwork that suggests there is a "filler". Was purchased from Arlington International and it's made in China.
Have not yet tested it, but visually it looks like the same pink/purple powder I'm used to seeing in the jar.
