MANGANESE DIOXIDE, ceramic grade, 1/2 POUND
Used as a colorant ingredient in ceramic glazes and clays. This is ceramic grade material and was purchased from Trinity Ceramic Supply. It is a fine powder (325 mesh), not granular manganese that is used to make speckles in clay. I am selling it because I have an excess supply and will be retiring from pottery soon. The material will be shipped securely double-bagged and packaged.
