Timelapse for casting GMT mirror 5 (VIDEO)
Caption
This timelapse shows several stages of the mirror casting process, including creating the light-weighted mirror mold, loading nearly 20 tons of borosilicate glass into the mold, and the furnace spinning at five revolutions per minute during "high fire," heating the glass to 1,165 degrees Celsius (2,129 F) for approximately five hours until it liquefies into the mold. GMT mirror 5 is being fabricated at the Richard F. Caris Mirror Lab at the University of Arizona.
