I picked up a pound or two of this dirt cheap ages ago, as it had been dropped and broken into little pieces about 4 inches long. But apparently pink is what I need right now - so I dragged it out.
It's a funny glass - almost shaded - a bunch of rods together look almost like venetian blinds. (Roll them, and the blinds close!) There is a strip of colour along one side, and the end result is stripey - almost like filigrana, but with a blur.
Pretty, isn't it?
