doped with a larger amount of potassium permanganate
| chemical formula | : K(ClO4, MnO4) |
| crystal class | : orthorhombic bipyramidal |
| growing method | : slowly cooling of the aquaeous solution |
| growing time | : app. 24 hours |
| crystal size | : up to 5 millimeters |
This specimen was grown from about 1,500 ml of solution to
which about one teaspoon of potassium permanganate had been
added.
Its notable that the crystal habit starts to change according to
the larger amount of permanganate included.
