Corning Ware, also written CorningWare, was originally a brand name for a unique glass-ceramic (Pyroceram) cookware resistant to thermal shock. It was first introduced in 1958 by Corning Glass Works (later Corning Inc.) in the United States. The brand was later spun off with the sale of the Corning Consumer Products Company subsidiary, now known as Corelle Brands.

Pyroceram has properties similar to glass and ceramic, and CorningWare was advertised as being capable of being taken from the refrigerator or freezer and used directly on the stovetop, in an oven or microwave, under a broiler, and go into a dishwasher. [1] :7

CorningWare is sold worldwide, and it is popular in North America, Asia, and Australia.

Discovery

In 1953 S. Donald Stookey of the Corning Research and Development Division accidentally discovered Pyroceram, a white glass-ceramic material capable of withstanding a thermal shock of up to 450 K (840 °F). He was working with photosensitive glass and placed a piece in a furnace, planning on heating it to 600 degrees Fahrenheit. When he checked on his sample, the furnace was at 900 degrees and the glass had turned milky white. He reached into the furnace with tongs to discard the sample, and it slipped and hit the floor without shattering. [2]

Pyroceram was originally used in the ballistic missile program as a heat-resistant material for nose cones. [3]

Discontinuation and reintroduction in the US

Originally manufactured primarily in the US, production of Pyroceram-based Corning Ware ceased in the States with the closure of the Martinsburg, West Virginia plant. While production continued in France, the product was temporarily unavailable in the US and the brand was relaunched as a line of stoneware-based bakeware in 2001. [4]

Corelle Brands' (then known as "World Kitchen") 2001 annual report indicated 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." [3]

In December 2008, the Pyroceram-based line of CorningWare was reintroduced in the US as CorningWare StoveTop. It is only manufactured in France at one of the few factories in the world still manufacturing vitroceramic cookware. One of the benefits of modern Pyroceram production is the ability to manufacture cookware without the use of arsenic.

in early 2022, sales of Pyroceram-based CorningWare were temporarily discontinued in the USA but reappeared on the market in early 2023. It continues to be sold in other regions of the world.

Patterns and products

The first pattern produced was Wheat; it was test marketed in 1958. It didn't test well with potential customers, and was dropped in favor of Blue Cornflower. [1] :14–16

Corning Ware cookware's first widely distributed pattern was the 'Blue Cornflower' pattern 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. [1] :7 Beyond the Blue Cornflower pattern, dozens of additional styles have been offered over the years such as 'Floral Bouquet', 'Spice O' Life', 'French White', and "Shadow Iris". [1]

Currently,[ when? ] Pyroceram-based Corning Ware is popular in the AsiaPacific region. Additional patterns have been created specifically for this market, including Bliss, Blue Elegance, Cool Pansies, Country Rose, Dainty Flora, Dandy Blossoms, Elegant City, European Herbs, Herb Country, Lilyville, Lush, Petite Trio, Plum, Salad Seasons and Warm Pansies among others.

The lids of CorningWare are typically made of Pyrex. Though some early lids were made of Pyroceram, most subsequent covers have been made of borosilicate or tempered soda-lime glass. Unlike the cookware, these lids have a lower tolerance for thermal shock and cannot be used under direct heat.

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 (percolator, drip), dinner service (Centura by Corning), Dutch ovens, frying pans, Grab-it bowls, loaf pans, percolators, pie plates, ramekins, restaurant ware (Pyroceram), roasters, saucepans, skillets, soufflé dishes, and teapots.

Corelle Brands (and later, Instant Brands) sells similar looking products under the CorningWare brand name that are made of glazed stoneware, rather than Pyroceram. The packaging for this type of CorningWare bakeware specifically states that they are not for stovetop use.

Visions, a brand of transparent stove top cookware originally created by Corning France and still being produced today,[ when? ] is made of a transparent version of Pyroceram. It features thermal traits very similar to CorningWare plus improved resistance to staining and the detrimental effects of acids and detergents.

Corelle, a brand name for break-resistant glass dishware also originally created by Corning Glass Works, has offered matching designs to many CorningWare patterns. [6] Care must be made to distinguish between Corning Ware cookware and tableware marketed under the Corelle and Pyrex brand names, as the thermal properties of the products are quite different.

Arc International, France, sells cookware that is equivalent to Corning Ware under various brand names including Arcoflam, Luminarc, and Arcoroc. Their Octime line of glass-ceramic saucepans and casseroles were rebadged for Princess House and sold as Nouveau cookware in the US and other select regions. Some of Arc's white vitroceramic cookware has also been sold under the Corning Ware brand name.

Glass-ceramics are polycrystalline materials produced through controlled crystallization of base glass, producing a fine uniform dispersion of crystals throughout the bulk material. Crystallization is accomplished by subjecting suitable glasses to a carefully regulated heat treatment schedule, resulting in the nucleation and growth of crystal phases. In many cases, the crystallization process can proceed to near completion, but in a small proportion of processes, the residual glass phase often remains.

Grab-it is a brand of Corning Ware cookware products easily identifiable by their uniform distinctive shape: a bowl with vertical sides and a rounded, concave tab handle. The name was first used for a versatile product which could safely go from refrigerator to stovetop, oven, broiler, or microwave, but later, inferior products, nearly identical in appearance but unsafe for stovetop or broiler use, were also branded as Corning Ware Grab-it. Before the introduction of the stoneware look-alike product, the Grab-it line was made of Pyroceram, a glass-ceramic material, by Corning Glass Works. Grab-its are notable as being among the first cookware specifically designed for microwave use. Their original design was recognized by the Smithsonian's Cooper–Hewitt, National Design Museum. Grab-its strongly resemble porringers.

<span class="mw-page-title-main">Revere Ware</span> Kitchenware line

Revere Ware was a line of consumer and commercial kitchen wares introduced in 1939 by the Revere Brass & Copper Corp. The line focuses primarily on consumer cookware such as skillets, sauce pans, stock pots, and tea kettles. Initially Revere Ware was the culmination of various innovative techniques developed during the 1930s, the most popular being construction of stainless steel with rivetlessly attached bakelite handles, copper-clad bases and rounded interiors for ease of cleaning. Over the next 40+ years, Revere Ware would introduce new series to position itself in competition with other manufacturers at various price points, or for specific specialty markets. In the early 1960s the profitability of Revere Ware began to level off. Coinciding with new series introductions, cost-cutting measures were implemented in the manufacture of the traditional cookware. The bakelite handles were changed from two piece to one, and the thickness of utensil walls and copper cladding were reduced.

Cer-vit is a family of glass-ceramic materials that were invented by Owens Illinois in the mid-1960s. Its principle ingredients are the oxides of lithium, aluminum and silicon. It is melted to form a glass which is then heat treated to nucleate and crystallize it into a material that is more than 90% microscopic crystals. Its formulation and heat treatment can be modified to produce a variety of material properties. One form is a material that is transparent and has a near zero thermal expansion. Its transparency is because the microscopic crystals are smaller than the wave length of light and are transparent, and its low thermal expansion is because they have a spodumene structure.
