I made some mica sheets with Flexi glass and used an electric die cutter to cut out these images
I then made a background from "tops and tails" and fired it face down to make a flatter surface to a tack fuse.
After capping it, I fired it to a full fuse after adding my images.
It did not work: I think the mica was too thin and once the binder burned off, as I assume it does, the thinnest areas virtually disappeared. So I set about saving it. I had some steel blue and cut out the same images in the glass and this is the result after I tack fused.
