If you want to know it exactly. Berliner Blau is the substance, that results
in the following reaction:

4 FeCl3  + 3 K4Fe(CN)6 --> Fe4[Fe8(CN)6]3 + 12 KCl

It is the blue pigment, that was also used for painting.

Betreff: [Histonet] Can someone tell me what Berliner Blau means?

Anyone know if "Berliner Blau" is an iron stain?
