Can you etch on brass with the same chemical and instructions as you list for copper?
Hi Deb! Brass is a copper alloy and etches beautifully with ferric chloride. It also etches nicely with the homemade solution of 50/50 hydrogen peroxide and muriatic acid (a.k.a. pool acid which is hydrochloric acid). You can etch nickle silver (a.k.a. German silver), which is also a copper alloy and contains no silver, with the same mordants.
