How can Copper Oxide patina (Green Copper) be achieved on Copper Surface
2005
Sir,
I am a small manufacturer of Copper patinated Sheets
I tried many times to patinate the Copper Sheets to a Green Color by using copper nitrate
⇦this on
eBay
or
Amazon [affil links]
.
Patination forms but wipes off by a touch of the hand.
Somebody suggested me to do Copper Oxidation by painting Copper Oxide on sheets.
Does this method work for Green Patination?
Please help
Thanks & best regards,
