Has anybody used 'liver of sulfur' on coins before?

I'm interested AR...as this mixture usually 'adds patina' (dk brown -black), usually the opposite of what folks do with their finds,...why would you want use it on coins?

Is there a 'look' your trying for and just experimenting?

Cheers
Gypsy

Yeah mate, re-patina experimenting for display. Some of those copper coins come out horrid and using a black texta and rubbing off the excess gave it that dark color again and also made the raised edges clearer. Just wondering.if anuones tried it before I have a go. Only other option is to maybe re coat them to cover the pits, but ud need some whiz bang awesome gear and business to do something like that.. wink

I also recon that 'liver of sulfur' is the most grotesque collaboration of words I have read in a while. It sounds absolutely disgusting lol lol

Ok, so you are after a 'dark' patina, and not the Unc. rosey pink finish?

If so, you need to re-activate the surface (it will have oils and such on it)..then let it sit and oxygenate...the 'age' look takes time....

I'd recommend the 'Armorall' de-greaser.....works best of any i have tried, especially on hyd. fluids and diesel..

It appears the SoL may work..perhaps try on an old 2c piece first if you don't trust it on PD's...

There are some electro-chemical ways to do this, but i wouldn't advise it myself...

Now, as to re-coating pit building....hmmm, who do i know who can do that?...hmmm devil cool

Sounds like your making Haggis yikes lol lol lol
What about heat treating the penny to change it's colour, the penny key ring I made for my GF the pennys were toast, annealed a few times while bending polished with autosol then maybe 4 months later started to look like real patina thumbsup long way to go to get blackening but after cleaning the right heat will change the colour to look cool cool
https://www.youtube.com/watch?v=X-E5bf9YfVk
I only use a small map gas torch thumbsup propane will be sufficient

Edit GF just got home and this is about 6 months of patina living in a hambag lol lol

coming along nicely but a long way of blackened

Awesome advice cheers guys!

What im after is to see if I can get a close to that dark green patina on pennies, or close to as well as what B5 has awesomely displayed here.
Yeah I dont like that rosey pink or the matte brown they can turn. Will be better in display the green than faded brown and patchy copper pits. Testing on bb's good idea GG

Im willing to let time and oxygen do its work, but im not sure it will totally work on those real damaged ones I more want to 'mask' over, but still keep the detail best as possible. Will try the suggestions and Gypsy - you mentioned it, so feed my ears of this electro-chemical way. Electrolysis or bit more fancier

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? yikes zomg science!

Never knew that AR yikes it'd be funny to see a black penny solar panel lol lol

this style may need sealing after, but I don't think the electroplating will build up enough to fill the pits in
alright check this out my perfect green penny 8) actually looks like it's anodized
1487299893_perfectgreenpenny_001.jpg
1487299893_perfectgreenpenny_002.jpg
Now this penny is a local penny and from the area it came from it should be toast yikes but.........something has me puzzled
I believe the penny may be naturally electroplated roll this came from right beside in between roots of a cut tree stump which has I think it's electrical main wires running underneath from sand swamp dirt yikes I'm thinking it was close enough to power wires and the tree stump rotting has coated it perfectly yikes maybe lol lol lol
The one where you brush it and let it dry in open air maybe dip it let it dry for a day and redip it every couple of days til the coating gets thick enough to seal
I'd first experiment with copper tube offcuts and when you have it sorted maybe try a BB, would beat cleaning 100 BB's for it mad roll
I don't want you guys to get the BB curse yikes the next 6 years of the ground raining BB's mad roll lol lol lol lol

When electroplating the 'pits' you only need to isolate the surrounding area so you can build them up....

Home set-ups are usually a set regulated supply,with slow and/or low transference....industrial set-ups allow for higher volume t/over, but require more attention as you can 'burn' the application... wink

I could have those pit's built up in 20-30 mins...then perhaps a little bit of polishing back to surface level..

Only way to stop the color going beyond your desired level is to seal it to put a stop to oxidizing...but it will continue to change over time regardless....just much slower than without. thumbsup

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 big_smile
Ive got some regulated power supplied gypsy but i think they were only 2 or 10 amp. Ill have to unbury them

Depending on the size of your anode/cathode used, and the surface size of a penny, the 2A for beginning would be slower, but better suited for first time attempts as you will have more control, as i hardly ever hit 10A while working small items.

If stuck with the 10A, all you can do is stand by while having a go...but as you are looking for that 'black' look, perhaps the 10A may be better suited as there's a possibility you will burn the finish.. big_smile thumbsup

Keep us updated on your results thumbsup

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 well yikes

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. wink
(Tin has a higher level of oxidation...)

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 etc smile

Love the shrine B5!! lol

All DC have the same ratio's..but the Nickel (Brinnel 667-1600) vs Tin (Brinnel 51-75) shows why the PD's are softer.

Re 2c vs 1c...same chemistry, just the gauge of the 2c being what it is...surface tension most likely within 5-10 Brinnel difference (if that).

Done by design to assist longevity in circulation... wink

Hmmmm.......more things to try yikes roll
https://www.youtube.com/watch?v=kMLT6PcWn4w
The issue I have is every time I look into it the end result has a mark from the cathode mark roll pretty amateurish
silver and gold plated yikes thumbsup thumbsup

https://www.sciencecompany.com/Turn-Cop … nnies.aspx
I might try that, gold and silver penny's would be cool yikes cool
don't know the result on this one but silver chloride plated yikes cool

Alright gota line some things up cool I'll do the silver and gold pennys
Zinc sulfate roll
https://www.bunnings.com.au/manutec-500 … r_p2961527
Is that sweet or do I need to get pharmacy grade Zinc sulfate
Where do I get Zinc metal mossy for free or close to free roll ops
The stuff on ebay is all from the States and can only find it from lab sellers roll
What can I scrap to get some?

Try lab supplies Aust. for local..

I recently picked up some bulk lab grade graphite for an 'experiment'...

Price was very competitive, and delivery was fast.

Hang on,....ok, try here;.. http://stores.ebay.com.au/rareitems/

Zinc Metal Mossy per;.. www.google.com.au/search?q=Zinc+metal+mossy&rlz=1C1MDNA_enAU593AU593&oq=Zinc+metal+mossy&aqs=chrome..69i57&sourceid=chrome&ie=UTF-8#q=australian+Zinc+metal+mossy

Don't know where you will get some 'free', but perhaps a local electroplater may have some?

I've seen it on lab sites for $10.95 but there's none near me or electroplaters roll my area sucks for anything out of the ordinary
And trying to avoid postage costs to avoid killing a 2c budget lol lol lol
There has to be something that has pure zinc in it
