ManganeseCompounds

I have not used these. Soluble manganese compounds can be hazardous. Safe disposal is also an issue.

 - information regarding use in studio ceramics

• Manganese Chloride
• Manganese Acetate (Manganese(II) acetate)
  • 700g/l at 20˚C
  • Can be made by reacting the oxide or carbonate with acetic acid

• Potassium Permanganate This is an oxidizer and can spontaneously combust with other materials. It is a contact hazard and an eye hazard.
  • Pottasium permanganate KMnO4?
  • at 25˚C 25 grams/liter, at 65˚C 250 gr/liter
  • strong oxidizer

• Manganese Hydroxide
  • https://en.wikipedia.org/wiki/Manganese(II)_hydroxide is not stable in air and is not very soluble.
