          here is the pecipe

          What you showed is copper patina, i have never used this ( dont use brass or copper ) but i guess you are after greenish patina i have some coleges who make antique replicas they use what we call "Blue stone " which practicly is copper dissolved into nitric acid and to enhance the "Antique " effect they berry the items in the garden for a week or two. Anyway i am after black patina for silver and here is the recipe i found on the net, havent tried it yet but maybe this weekend, wish you good luck.

          Liver of sulphur is not a chemical compound but is a mixture, prepared as a brown mass by fusing sulphur and potassium carbonate.(P. J. Durant 1954, General and Inorganic Chemistrypage 491)

          6S + 3K2CO3 = 2K2S2 + K2S2O3 + 3CO2

          When I last prepared this I melted sulphur and slowly added a measured quantity of potassium carbonate as per the above formulae.

          The mixture was stirred until bubbling ceased and was then allowed to cool. It was then broken up and bottled. The mixture was stable.

          A dilute solution can be used to tarnish copper and other metals.

          Note that hydrogen sulphides are also evolved which smell bad in low concentration but are poisonous in higher concentrations. Thus a fume cupboard is mandatory.
