A fine Modern casserole by Corning in their Centura ware. This white body is somewhere between porcelain and glass and was a step before the Corelle body, made in the mid- to late 1960s.
This piece is in their Buffet Server line, a fine white Modern piece with a Black heat-proof (Bakelite) handle. It's a 1.5 quart casserole.
Size: 9.125" across the handles, 6.675" in diameter, 5.5" tall.
Condition: completely as new, no wear or damage. No interior wear or utensil marks. This is about as mint as you'll find.
Mark: Corning Buffet Server backstamp on the bottom.
