The oxidizing of copper or bronze is not a simple matter to achieve good results. It takes years to master this ART. Results are dependent on many variables, some are within the artists control. The substrate has much to do with the end result and can present many challenges to the artist. In short, I know of no publication that would guide the "lay-person" into this process without hands-on experience.

Hot immersion(9o C)!2-5 min.

Green for cooper and its alloys:

ammonium carbonate......

25o gm ammonium chloride.......

For best result you must use brown colour first and then green!

Only grease and oxide free objects can be coloured!
