Aluminization Preparations

Leave a Comment
On July 26, MMT staff stripped the aluminum coating from our 6.5m mirror to prepare for its realuminization in a few weeks. Using various cleaning agents, some mopped while others sprayed. Soon only a small portion of coating remained, revealing the honeycomb structure beneath the glass. Next, all hands on deck to carefully dry the surface, followed by covering the glass to keep it clean until it is recoated in several weeks.
