My experience with Manganese is that it is fugative and needs to be worked as soon as it fines. The hotter you get it the faster it burns out. It tends to sink to the bottom of the pot. It is phototropic, that is, it will deepen in color somewhat when the piece is placed in the sun. Those are notes from the dim dark past. Use the carbonate or dioxide and you get great purple foam and you can make Lava glass.
