This is a 20 gauge disc of red brass that measures 1 and 3/8″. When etching with ferric chloride you can sweat solder on sterling or fine silver and use it as a ‘resist’ because the ferric will not etch silver. Because you will be submerging the piece in the ferric make sure you have a good tight sweat solder. In this sample I did not put any kind of resist on the red brass area except to put magic marker on the edges. The lines that you see on the red brass are done by the ferric. Obviously you could put a resist on it if that was your design intent. I sweat soldered ( with hard) fine silver to the red brass so I could put enamel on it. I used a transparent blue and stoned it a bit after it was fired. More dimension could be built up here with the silver and enameled too. After the silver was soldered on the surface was textured with a scribe and hammer ( although you could solder on a piece that had been textured already in the mill etc) and then the whole piece was dapped a bit.
I found some small plastic trays that were divided. The dividers were sealed to the bottom so I could use each little section for etching a small piece without using a lot of ferric. I used clear tape to suspend the piece in the ferric. Great for little tests like this.
I think I would like a bigger piece with a delicate silver tree on red brass with certain areas enameled and maybe incorporate some of the steel wire shapes in the enamel ( see tutorials on my website janecather.com)
