Default Re: Black oxide coating on brass

Am I right in thinking that sugar of lead is lead acetate? Might not be easy to obtain these days. However, I imagine it can be made using lead (shot or fishing weights), vinegar and an oxidising agent like hydrogen peroxide. A resident chemist may be able to advise.
