get a copy of IPS ( introductory to physical science )
its an 8th grade science text book.
the first experiment is plating silver out of a solution onto a copper wire.
it says EVERYTHING you need to know.
it isn't hard to do anything yourself but some people attempt, and fail
and then they dump their fixer in their back yard or down the drain because they don't
want to waste anymore time or money experimenting ...
