Some interesting things about the lamp. The bottle is basically the same bottle used in an Astrobaby and base and bottle is interchangeable. The screw cap uses the same thread spacing as the caps used by Mathmos is 28MM in diameter. The gold cap seems to be a typical gold cap, but it is glued on to a black screw cap.
I'm going to attempt to restore the formula. It overheats quickly, has a lot of white powder has separated from the wax, and the wax is sticking to the glass.
