Interesting Facts about Pattern: - Desert Dawn was one of the first opal ware Pyrex collections to hit the consumer market. Pattern Description: The 1955 release of Desert Dawn was comprised of two colors, Desert Pink and Desert Yellow. These were two of the first opal ware Pyrex products to hit the market. An advertisement in the August issue of LIFE magazine claimed that Desert Dawn was “A new color fashion in bakingware for both cooking and serving.” While both were solid colors, the pink and yellow versions of Desert Dawn were randomly speckled with tiny brown dots. Each color was released as a pie plate, in two sizes of round casseroles, and in a series of bake ware that included a loaf pan, cake pan, square pan, and two sizes of a rectangular pan. Desert Dawn in Pink and Yellow was discontinued in 1956.
