Green for copper/copper alloys:
200 gm ammonium chloride
200 gm ammonium carbonate
1 lit water Can be sprayed or brushed on object!

For best results solution must be used on black to brown ground colour
(5 gm copper sulphate
50 gm potassium permanganate
1 lit water-hot immersion/
90 C/or 10 gm potassium polysulfide/
20 gm ammonium chloride/
1 lit water- use only fresh solution!).
