For the last prints, I left them in the acid for about 20 minutes and I drew with a zig posterman marker.  Now I wanted to try new things.  I started painting with Bitumen to get a painterly print.  I also had an idea to attach a hospital bed to a drip to give off the impression that the Irish healthcare system is sick.  Here are the experimental prints.

I kept this in the acid for about 15 minutes.  I rocked the plate back and forth to blend the tones together.

I put this in the acid on 3 separate occasions to get 3 tones.  I wanted to blend them together.
