Fire-King Peach Lustre round casserole dish

These pieces are iconic mid-century American kitchenware, highly recognizable by their iridescent, orange-tinted "peach" finish over a white milk glass base.

• Era: Likely 1950s–1960s.

• Material: Borosilicate "Oven Proof" milk glass with a fired-on luster finish.

• Usage: While "Oven Proof," it is generally recommended to use these for serving rather than high-heat baking today, as the glass can become brittle over 70 years, and heat further degrades the luster.
