"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 [affil. link to info/product on Amazon].

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,
