Some Information on Etching

Most etching is probably done on printed circuit boards -etching
copper off. Most art related etching is done in printmaking etching
various materials but not the precious metals. Enamelers will etch
copper and silver mostly.

I have posted on this ad nausea-- search archives but here are some
sources. The circuit board etches will not work on silver. It
requires ferric nitrate for a chemical etch.

The electrolytic systems are the safest from a chemical exposure

There are many more. also search resists - Orchid first then google.

material availability may depend on where you live so it helps to
give a general idea.

Hazmat “rules” are often not correctly applied-- you can’t do much
about this.

read and enjoy
