| 説明 | One of our quartz halogen projector work lights burned out - or more precisely, it got bumped, and the glass tube cracked. It snapped open at one end, and created an iridescent effect on the surface of the element. I'm assuming that as the air entered the crack in the tube, it reacted with the metal in the element, which was in the process of cooling off. So as the oxygen made its way down the tube it reacted with first with very hot metal, and then as it progressed, it met with cooler and cooler metal, creating a rainbow spectrum of colors, which then got jumbled up as the wound-up metal element broke free and unwound itself, bunching up in the middle. |
