CorningWare, also written Corning Ware, was originally a brand name for a unique pyroceramic glass cookware resistant to thermal shock. It was first introduced in 1958 by Corning Glass Works. CorningWare is notable for the fact that it can be used directly on the stovetop.

In 1953, Dr. S. Donald Stookey of the Corning Research and Development Division invented Pyroceram, a white glass-ceramic material capable of withstanding a thermal shock (sudden temperature change) of up to 450 °C (840 °F). It evolved from materials originally developed for a U.S. ballistic missile program, and Stookey's research involved heat-resistant material for nose cones.[1]

Patterns and products

Corning Ware's range/oven-to-table service first featured the blue 'Cornflower' pattern decoration, designed by Joseph Baum, an artist at the Charles Brunelle Advertising Agency in Hartford, Connecticut. It became the trademark of Corning consumer products for three decades. Following the 'Cornflower' pattern, many additional patterns were offered by Corning over the years. Care must be made to distinguish between CorningWare patterns for cookware made of Pyroceram, and patterns for tableware marketed under the Corelle or Pyrex brand names, all by Corning. Many Corning Ware patterns were also used for Corelle tableware, which can make distinguishing difficult.

Those patterns which included cookware made of Pyroceram are: Abundance, All/Just White, All/Just Beige, American Oil Star/Snowflake, April, Autumn Meadow (Imoco), Avocado (round), Avocado Medallion (Shell Oil), Blue Dusk, Blue Hearts, Blue Heather, Blue Medallion (Shell Oil), Blue Scroll (Microwave browner), Blue Velvet, Butterscotch (Round), Callaway, Calypso, Christmas Tree (Furio Home), Classic Black, Country Cornflower, Country Cottage, Country Festival, Deco, Delicious, Duck, English Breakfast, English Meadow, Evening Song, European Herbs, Farm Fresh, Floral Bouquet (3 editions), Forever Yours, French Bisque, French Bleu, French White (also with blue or gold rims), French White II, Fresh Cut, Friendship, Fruit Basket, Garden Cat, Garden Harvest, Harvest (square), Indian Summer, Jardin, Laurel, Lynwood Green, Lyrics, Merry Mushroom (round), Mille Fleur, Morning Glory, My Garden, Nature's Bounty, Needle Point (JC Penney Exclusive), Oceanview, Orchard Rose, Pastel Bouquet, Peach Floral, Peach Garland, Peony, Pink Trio, Platinum Filigree, Provincial Blue, Quilt, Renaissance, Rosemarie, Shadow Iris, Shangri-La, Silk & Roses, Simple Lines, Spice o' Life, Stix, Strawberry Sundae, Summer Blush, Summerhill, Sunsation, Symphony, Trefoil, Wheat, Wheat Sheaf (Green Wheat), White Flora, Wildflower and Vineyard.

More than 750 million pieces of Corning Ware's range/oven-to-table service have been manufactured since its inception. A partial product list includes: browning skillets, cake pans, casserole dishes, coffee pots (Drip), dinner service (Centura), dutch ovens, frying pans, grab-it bowls, loaf pans, percolators, pie plates, ramekins, restaurant ware (Pyroceram), roasters, sauce pans, skillets, souffle dishes, and teapots.


The original pyroceramic glass version of CorningWare was removed from the U.S. market in the late 1990s. [2]

Originally manufactured by Corning Glass Works, the CorningWare and Corelle brand names are now owned by World Kitchens Incorporated of Rosemont, Illinois, which relaunched the brand name in 2001.[3]

The World Kitchens's 2001 annual report shows that the stovetop and dinnerware product lines were halted at the end of the century "as part of a program designed to reduce costs through the elimination of under-utilized capacity, unprofitable product lines, and increased utilization of the remaining facilities."[1] Facilities in Charleroi, Pennsylvania and Clinton, Illinois were closed. Several of the Corelle patterns have been discontinued since 2010. One of these was the very popular 'Abundance' pattern.

Reintroduction of CorningWare and Pyroflam

In 2009, the stovetop line of CorningWare was reintroduced by World Kitchens. The cookware is manufactured by Keraglass/Eurokera (a subsidiary of Corning also specialised in vitroceramics for cooktop panels and equipment for laboratories) in Bagneaux-Sur-Loing, France. This is the only factory in the world still manufacturing vitroceramics (aluminosilicate glass) for cookware. At the time it restarted the production of CorningWare, Keraglass/Eurokera was able to abandon the use of arsenic in the manufacture of their vitroceramics, thanks to the modern technology of their newly built oven.

In Europe, it is ARC who sells equivalent cookware to CorningWare under the name Pyroflam with a slightly different design. Since 2009, Pyroflam has been manufactured in the same French factory as CorningWare.

The lids of CorningWare and Pyroflam are not made of vitroceramic material. The lids of pieces in the Visions and Pyroflam Amber lines are made soda-lime glass, and lids for the white collection are made of borosilicate glass. Unlike the vitroceramic cookware, these lids cannot touch burners or fire directly, but they do fine in the oven (if not touching the source of heat) or on the stovetop, as long as they are over their vitroceramic bases.

CorningWare is sold worldwide, and it is popular in Canada, United States, and Australia.

Other manufacturers of similar oven-to-table products

World Kitchens sells similar looking products under the CorningWare brand name that are common white glazed stoneware. The packaging for these newer CorningWare branded cookware products say specifically that they are not for stovetop use.

World Kitchens does still sell Pyroceram Corning Ware to its Asia–Pacific market. These items can be purchased in local department stores there. Additional patterns have been created for this market, including Bliss, Blue Elegance, Country Rose, Dainty Flora, Dandy Blossoms, Elegant City, European Herbs, Herb Country, Lilyville, Lush, Petite Trio, Plum, Salad Seasons and Warm Pansies.

Corelle is the brand name for the highly break-resistant glass dishware, using a special hub lamination process that thermally bonds three layers of glass — a core center surrounded by top and bottom layers of "skin" or "glaze" glass. The glass was decorated using unique enamels that actually became a part of the glass, creating durable, scratch-resistant designs.[4] Both of these products were originally developed by the Corning Glass Works in Corning, New York.
