Hellos -
I was going to experiment with wet plate in the coming months.
In my stock shelf I have an old bottle of ferrous sulfate.. cant remember when I bought it.
As I remember, is it not supposed to be green crystal?
The bottle I have is not. It is a sandy light brown, obviously oxidized.
Is this agent usable in this state? [dont have much experience with this agent]
thanks a bunch!
