Precleaning and degreasing of brass
I am creating a line of antique reproduction lamps and lanterns. Several of the parts are brass and require darkening for the look I am after. I am experimenting with 1) Barium Sulfide 2) ammonium Sulfide 3) ammonia

I can get a nice color by taking my time and scratch brushing and individually dipping or fuming each piece. But I need to rapidly clean and patina 20 to 30 parts at time. Is anybody aware of a chemical that will accomplish this by simply dipping and rinsing?
I have ordered a copy of
"The Colouring, Bronzing & Patination of Metals" [on
eBay,
Amazon,
AbeBooks affil links]
, but won't receive it for several days.
Thanx in advance,
