The Giant Glass of Palomar
The article recounts Dr George Ellery Hale's quest to build a 200 inch reflecting telescope for Mount Wilson and the parallel development of the Palomar project. It covers the failed quartz attempts, the Pyrex solution, and McCauley’s careful casting and annealing of giant glass disks, including the dramatic 1894 disk trials, the flood test, and the eventual readiness of Hale to have his mirror.
