This is a hammered sheet steel piece. After drawing the image onto the metal I then trace the lines with a chisel to set the steel and to also see the drawing of the back side from which I hammer it. In some cases I hammer from both sides. I applied an acid copper wash, then I apply a clear coat.
Smoked Fish and another similar one with a different patina called “Fish on Ice” were my idea of a fish fossil, tough it isn’t of a fish you find in nature. I used my computer to redesign the fish skeleton, I flipped the spine to fill in the gut because I needed it to be more symmetrical.
