How can i use silver from x ray films to eletroplate a soldering iron tip?
That's it: i have a ton of old/useless x-ray films and a bare copper iron tip.
I usually clean the x ray films with sodium chloride (at 2%, from bleach) to use the pvc sheets to make stencils. Once i left the resulting solution to air dry. It took something like a week for the 25cc of liquid to evaporate and left some crusty, green matter - which, i'm pretty sure,had silver in it.
The questions are: what is that solution? Can it be used in eletroplating as-is or need to be refined? If yes, how?
Put your brains to work, my friends! A silver-coated soldering iron tip is something of our common interest, i believe.
