i think you are very right with your guess about potassium permanganate.
under the sticker with the price i found the following: "übermangansaures kali äusserlich".
this means over/super manganese saur potassium.
so i believe this is as close as you can get to potassium permanganate.
(äusserlich means external applying it to the body, not swallowing it (it is meant to be used
medically)).
the old names for the chemicals are somehow confusing if one (like i) doesn't understand the modern
names as it would be nice.
i understand the thing with the pigments, as said as a precaution i will not color it for the first
trials at all.
