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 jewellery and knows that two of the ingredients are:
1. sulpher (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 /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 Sulphur [linked by editor to product info at MisterArt] can be used too(25 gm potassium polysulphide/1 lit water solution,90 C temp.,for best results brass must be copper plated))

Good luck!
