I've been experimenting with making looser forms of fused and slumped glass, and I think this works pretty well. I let the ends and edges melt without any restriction, and I don't do anything to finish it. By that, I mean, I don't grind and polish the edges for a finer look. The middle section has white glass canes criss-crossing each other in two layers. When the two layers are fused together, tiny air bubbles are trapped in the spaces where the canes cross. It's similar to the Italian method of making reticello, which places one glass bubble of canes twisted in one direction, inside a glass bubble of canes twisted in the other direction. When the bubbles are inflated, air is trapped where the canes cross.
