Here is the formula:
1 oz. Ammonium Chloride
1 oz. Cupric Chloride
1 oz. Cupric Sulfate
1 oz. Cupric Carbonate
1 Pint Distilled Water
It takes about three hours for this patina to work. Note that the formula above is quite concentrated. You may want to dilute it with a third more water.
Allow this patina to sit for at least six hours before spraying it with a lacquer. Remember that you need to apply two coats of lacquer before waxing (let lacquer cure for six hours).
