This chandelier conservation project, which involved the center lighting fixture in the Senate Reception Chamber focused on cleaning the metalworkand its glass globes.  At the same time we were asked to rectify a persistent short circuit problem associated with the lights within the globes.  We discovered that manipulating of the fixtures caused them to make contact with the metal frame which held the globes.  As a solution we injected each metal frame with non flammable foam which secured the fixture and prevented it from moving.  This solved the problem.
