HEY LOOK NEW ART
And so Chim adds another thing to the list of art techniques in which she dabbles.
Playing with acid is fun.
Right, so, metal etching. The top two photos show the two sides of each brass disc, with larger individual shots underneath. They're shown in the order I did them. The first two (the music ones) I just kind of went to town on with a permanent marker, tossed them in the acid bath and hoped for the best.
The other three I was experimenting with the toner transfer method. It can bite me. For every one time it worked, there were four times it didn't. I think I'll keep with the same way I transfer patterns for glass engraving: spray paint through a stencil, then scratch off what I don't need.
There are five pieces with the obverse and reverse shown side by side, not ten separate ones. 4cm diameter and 1mm thick, except the eighth note piece, which is 3.3cm wide. ((1-9/32" by 3/64" and 1-5/32" by 3/64")

Time Spent: Not really sure. Anywhere from ten minutes to an hour getting the designs on the brass, then marinating them in the acid for anywhere from ten minutes to an hour and a half. It doesn't etch very fast, so there isn't much worry that it's going to eat right through the brass.
