Recipe to oxidize brass, copper and pewter




We are a shop producing light fittings (chandelier's and lamps).
I have heard there is a recipe for aging brass. (I realize I can buy a Brass aging solution) but for our purposes it would be more economical to make it ourselves. One of the staff used to age jewelry and knows that two of the ingredients are:
1. sulfur (rock form?)
2. Methylated Spirits
Would anyone know the remaining ingredients and how to make the solution?
Thank you

Safe and simple brass browning solution is copper sulphate /potassium permanganate this on eBay or Amazon [affil links] /water solution(50 gm copper sulphate/5 gm potassium permanganate/1 lit water solution,90 °C temperature,only for oxide and grease free objects)! Liver of sulfur this on eBay or Amazon [affil links] can be used too (25 gm potassium polysulfide/1 lit water solution,90 °C temp.,for best results brass must be copper plated))

Good luck!
