Casserole Dish with Lid. Pyroceram material(1958)was discovered from military use and was initially used for ballistic nose missiles. These dishes were produced to withstand very high temperatures and go directly from the freezer when the original lids were used. This bowl is in Very Good Used Condition, and was produced 1961-1966, possibly 3yrs after the first corning bowls were produced. Dish has utensil marks/scratches on inside bottom as shown. RARE Stamp which I believe was a manufacturing error(made in USA is missing). This error should make the bowl worth even more. If anyone has seen this error please let me know. See all 12 photos for best description. Glass Pyrex Lid is very good. Referenced on corning Ware 411 blogs and rarest.org Alaska and Hawaii residents may be responsible for excess shipping costs.
