So a chemistry lab at my university was giving away some chemicals and I scored on a 1 pound jar of Potassium Permanganate for free! Pretty sweet deal since I was looking to buy some anyway. I've read all about staining antlers with PP, but what about whole skulls? Does any one have pictures of a skull stained with PP or has anyone done it themselves? What are the results like? I want to make a skull that looks fossilized or like a La Brea Tar Pits specimen. Thanks!
