The backs of the discs are stuck to tape, and they'll be suspended in an acid bath
Discs are soaked in a thoroughly disgusting acid solution for a half hour. I'm supposed to be wearing rubber gloves, an apron, and boots. I did this in shorts and flip flops and survived.
When done, they look equally disgusting. Some people call this art. I call it a sloppy mess in my backyard.
Once they're pulled out of the acid, they're soaked in a baking soda and water solution to stop the etching process. This stuff foams...not for the timid.
When I pulled them out they still had ink on them, but they now have designs etched on them.
I removed the ink from most of these with pure acetone, and left a few dirty to show you.
Next I threw them in my rock tumbler for a few minutes to try to clean them up some more.
Getting ready to apply a patina fired finish with my blowtorch, I cleaned them with lemon juice and a Qtip to remove any dirt or oil from my fingers.
About to torch them with a butane torch (no pics...I can't work with fire and photograph at the same time)
The same piece after I torched it for a few seconds. It's darker than I'd like, so I'm going to go for less time on the rest.
The unetched backs of the discs before I torch them.
After torching for a few seconds, same discs...I'm loving the colors!
Same discs, only flipped to show the etched side.
The discs have been brushed with a clear enamel to keep the patina from changing over time. These are finished and ready for use.
