This is fused glass. I call this technique glass carving. It's not really carved but it ends up getting that look to it. The piece has been slumped over layers of fiber paper to make the image of the bird.
This glass has an iridized surface, so when the light hits it from the front it actually reflects several colors which look like a sunset. This picture is backlit so it is showing the actual color of the transparent glass, which also shows the detail of the bird a little better.
Glass is so incredibly hard to photograph. My normal background was too dark and you couldn't see the detail so I had to make do with white sheets. This picture does not do the piece justice. It's so much better in person
