Patination of lead
2005
I want to produce an authentic looking patina on recently moulded lead. Under natural conditions lead seems to patinate black-ish or white-ish, depending on (presumably) atmospheric conditions.
How can I make new lead look old - black or white would suit.
Thanks,

Some solutions for patination of lead objects:
1. 40% solution of potassium polysulfide
in water
2. 100 gm iron chloride
500 ml HCl
1 lit water
3. 5 gm copper sulphate
20 gm potassium permanganate
⇦this on
eBay or
Amazon [affil links]
1 lit water
Good luck!
