CorningWare 'Cornflower Blue' Pyroceram Collection

Story

In 1953, a Corning scientist accidentally overheated a piece of photosensitive glass to 900°C, expecting a melted mess. Instead, he discovered a super-strong, heat-resistant ceramic that could withstand extreme temperature shocks.

Maker / Origin

Corning Glass Works, founded in 1851, was already famous for industrial glass and Pyrex when they introduced CorningWare in 1958. Their development of Pyroceram—originally used for guided missile nose cones—revolutionized domestic cooking by allowing a dish to go directly from the freezer to a hot oven without shattering.

Condition & Value

The pieces appear to be in good vintage condition with bright graphics. The percolator's metal band and handle look secure, though the interior heating elements/basket must be checked for completeness. Minor metal rub marks on the white Pyroceram can usually be cleaned, but deep scratches or chips to the glass lids will reduce value.
