Vancouver-based glass artist Jeff Burnette has made several pieces that look like rayguns from classic science fiction. Here's how he does this delicate work:
These are blown and manipulated hot glass objects. A transparent colour is picked up on the pipe, then clear glass is gathered on top. The piece is then blown out and shaped to the desired form. Coloured bits are added. Once the bits are in place, the handle and trigger are applied to the piece, the Raygun is then knocked off the blowpipe into the annealer to cool over a fifteen-hour cycle.
Once cooled, the piece is ground and sent out for silvering or completed. The Raygun is a bubble with a transparent colour on the inside. The silvering is a solution of silver nitrate, ammonia, and distilled water that is mixed and poured into the open end of the gun. The silver sticks to the inside of the piece just like a mirror. The final step is chemically bonding a machined stainless steel end to the piece.
