Many years ago I made a few mathematical models from paper, things like cubes, an icosahedron and the great stellated dodecahedron.
Move forwards a few years and I had the idea of doing the same thing in glass as a lampshade. The result is simple and functional.
It's made using sheets of glass and copper foil, in the Tiffany method of stained glass'. The copper foil is sticky on one side and I ran that down the edge of the glass and then soldered the edges together. One of the panes of glass has a hinge fabricated from copper wire and copper sheet, so that the bulb can be changed.
The bulk holder itself is mounted on a frame that is made from copper wire, for added strength. (The first design came apart as the weight of the lantern pulled the copper foil glue from the sheets of glass, so the final lampshade has a copper wire frame completely supporting the entire structure inside. That has worked for a year or so).
