I did this piece experimenting with copper mesh, dichroic (metallic looking) glass, stringer, and decals. I like the shapes, color, and movement of abstract art.
Recently, I tried a piece of copper mesh between float glass (window glass). I fired it to a contour fire (not quite as hot as a full fire). I don't really notice any air bubbles in this piece. What you can't really see above is there are tiny air bubbles inside the mesh of the copper pieces above.
In the piece below, I placed a green grape vine leaf in between two pieces of float glass and fired to a contour. Most of the leaf burned off and left an ash impression. There is a small piece in the middle that didn't burn off completely. When I picked up the glass the small leaf piece slipped. Had I used a full fire (higher temperature than contour), I believe the entire leaf would have burned off. I will definitely do this again. I like the results.
