Extremely Rare Corning Ware “Platinum Filigree” 2½-Quart Casserole with Lid (P-440-B)

This exquisite casserole represents one of the most elegant offerings in Corning Ware’s Limited Edition Gift Line, produced around 1966. The ornate silver-scroll design—aptly named “Platinum Filigree”—wraps gracefully around the creamy Pyroceram body, catching light with its refined detailing and offering a timeless, sophisticated look. 

Marked on the bottom as P‑440‑B, this 2½-quart size was part of the “Royal Buffet” set, originally sold with a candle-warming base for luxurious table presentation. Only a very limited number were ever made, making surviving examples especially coveted among collectors of mid-century Corning Ware. 

At a generous 2½-quart capacity, this piece blends function and artistry, ideal for everything from elegant serving to display. If you value rarity, craftsmanship, and mid-century design, this Platinum Filigree dish is truly a standout.
