Has anybody used 'liver of sulfur' on coins before?
Never knew that AR it'd be funny to see a black penny solar panel :lol: :lol:AtomRat said:B5 - have you ever considered that after you have heated a penny to red hot and it has the black carbon crust.. Youve actually made a solar panel? zomg science!
don't keep me in suspense was it a greenyAtomRat said:Guess what I dug all day today B5.. :lol:
I've seen a guy that uses an old phone charger to deplate silver plate in a jar but..... can't remember which chem he used and worked wellAtomRat said:Gee i think i might have a go at every method supplied by you blokes, didnt realise soo many! And some of them chems used look fun too
Ive got some regulated power supplied gypsy but i think they were only 2 or 10 amp. Ill have to unbury them
Certainly forethought the different alloy within the different coins! Al and I were speaking today about how strong the 1c coins are and I said its proba ly due to higher copper content / conductivity, where as maybe the 2c has a bit of nickel or something etcGypsyGoldAu said:Just a reminder....the difference between the PD's and DC's in the 'copper's'...should you 'practice' on the DC the finish you decide upon may not end up that way on the PD's....PD's had Tin, whereas the DC has nickel, as such a slightly different, though similar, reaction/finish.
(Tin has a higher level of oxidation...)
