In 1929, Corning Glass Works accepted a commission to make a 200-inch Pyrex disk for use in a reflecting telescope on Mount Palomar in California. After several trial castings of smaller disks, Corning poured a 200-inch disk in 1934. When part of the mold broke loose, the disk was ruined, but it was annealed (cooled slowly) as an experiment to gather information necessary for a second, successful casting later that year. This is the initial disk, which has been displayed at The Corning Museum of Glass since it opened.
