This technique is one that I developed. I have been successful in reproducing photo-images in Iron. Set against an oxidized copper background, the viewer can experience real rusted iron buildings in 3D but on a two-dimensional canvas.
These pieces take time to cure and I have only done 2. This one, and one on glass (See: www.nascentartny.com for the other one). So, if you decide that you want one like this (on canvas), you will have a piece of my work that is rather unique compared to the typical body of work for which I am often known. And it's always a fun story to tell your friends about the painting you commissioned just for you.
