Potassium perchlorate / potassium permanganate is one of the few good examples
of a crystal with mixed anions.
This little specimen was grown from about 1,500 ml solution to which only a few
small crystal pieces of potassium permanganate had been added.
As you may know the permanganate anion is one of the strongest inorganic "dyes"
known, even traces can produce a slight pinkish hue.
