A beautiful and highly collectible Mid Century Modern covered casserole designed by Ben Seibel for Iroquois China as part of the iconic Impromptu line.

This piece features the classic atomic triangular motif in warm orange tones, paired with a sculptural lid and clean white glaze—an unmistakable example of 1950s modernist American dinnerware. The form is elegant yet functional, making it equally perfect for display or use.
