Welcome to Sciencemadness. We have a designated thread for pictures like these, I would post them there next time. Overall, great pictures though!

How did you do it?

Electrolysis, the more dilute the solution the more it favours branching. I did this a long time ago but those are way better than I managed. What range of current and concentration are you using Gleb?

I am assuming Cu and Ag ?

That last one or the third to last might be tin.
Take a look at the video posted in Pretty Pictures.

I think it's pretty. https://www.youtube.com/watch?v=G1sq4hnrBgM

hmm possibly Sn
would have been nice to have some labels...

4, 5, 6 - Cu, sulfate
7 - Ni, sulfate
8 - Pb, acetate
10 - Zn, acetate
1, 2, 3, 9 - Cu and Bi, nitrate
All are concentrated solutions. And high currents (1-2 A)

from nitrates?
