Corning Ware 'Cornflower Blue' Casserole Dish

Photo reference

1 uploaded photo

Overview

This is the definitive icon of mid-century American kitchenware, featuring the 'Cornflower Blue' floral sprig on a white Pyroceram body.

Story

The material this dish is made of was born from a laboratory accident in 1953 when scientist S. Donald Stookey overheated a piece of photosensitive glass to 900°C.

Maker / Origin

Corning Glass Works is a titan of American innovation, responsible for crafting the glass for Thomas Edison's first light bulbs and the windows of the Space Shuttle.

Condition & Value

The piece appears to be in excellent vintage condition with a crisp, vibrant blue decal and a clear, unchipped lid. Minor 'metal marks' from spoons or gray scuffs on the bottom are common but can often be cleaned; their absence would maintain the higher value range. Excellent condition commands a premium.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

▲ Strong maker attribution with credible period details
▲ Better-than-average condition for the category
▲ Broader demand rises when presentation and finish feel intact

Concerns

▼ Decorative-only demand limits the ceiling
▼ Surface wear or missing provenance can compress the range fast
▼ Regional sale lanes often underperform specialist venues
