Yes neon pink, just imaging being outshot in a competition by a guy shooting pink ammo. How embarassing.
I can't believe I still had this. I gave it a go about 40 years ago.
Black: Wash and pickle the brass in weak (2 to 4 %) sulphuric acid. Mix 7 ounces copper carbonate in 3 pints of stronger ammonia (26 to 28%) and then add 1 qt warm water. Immerse cases until colour appears.
Olive: Mix 4 parts copper sulfate and two parts sal ammonia into 100 parts water. Immerse clean, dry cases until colour is produced; then wash thoroughly and dry.
Red: Mix 75 grains potassium chlorate, 30 grains nickle carbonate, and 75 grains salt of nickle into 10 ounces distilled water. Immerse brase until desired color is produced. First will be yellowl-brown, but will progress to fire red of a period of hours-the longer the brighter.
Iridescent: Add one part of lead acetate and 3 parts sodium hyposulphite to 48 parts water. Immerse clean dry caases until the desired color appears. Rinse carefully in clean warm water and let dry without disturbance. Once dry, the colors last quite well, but rub off when first out of the solution.
Note to self: Salt of nickel is nickel chloride.
40 years ago the local druggist knew what this stuff was. Nowadays, ha!
