Not sure if this is the right forum to ask this, but what kind of Potassium permanganate do you buy for staining antlers? It looks like I can buy it online in liquid and solid form from all sorts of suppliers. I need to get some for staining sun-bleached antlers. Is this what I need? http://www.sciencecompany.com/Potassium-Permanganate-100g-P6403.aspx If not, where do you guys buy it? I would appreciate any help! Thanks!
