Rainbow patina

I continue my experiments with natural materials in electroplating.

I mastered the process of electrochemical patination.
This is similar to the process of electroplating - 
electric power supply + electrolyte 
(composition of the solution is different from the copper plating electrolyte). 
Depending on the solution temperature and immersion time the leaves are painted in a rainbow of colors - 
from golden to dark purple.

I have not yet learned how to control this process, 
so each new detail has a unique coloring.
And it's very interesting :)
