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.
Cookware and bakeware is food preparation equipment, such as cooking pots, pans, baking sheets etc. used in kitchens. Cookware is used on a stove or range cooktop, while bakeware is used in an oven. Some utensils are considered both cookware and bakeware.
Pyrex is a brand introduced by Corning Inc. in 1915 for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. It was later expanded in the 1930s to include kitchenware products made of soda–lime glass and other materials.
Corning Incorporated is an American multinational technology company that specializes in specialty glass, ceramics, and related materials and technologies including advanced optics, primarily for industrial and scientific applications. The company was named Corning Glass Works until 1989. Corning divested its consumer product lines in 1998 by selling the Corning Consumer Products Company subsidiary to Borden.
Fire-King is an Anchor Hocking brand of glassware similar to Pyrex. It was formerly made of low expansion borosilicate glass and ideal for oven use. Currently it is made of tempered soda-lime-silicate glass in the US and borosilicate in Japan
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion, making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about 165 °C (300 °F). It is commonly used for the construction of reagent bottles and flasks, as well as lighting, electronics, and cookware.
Le Creuset is a French-Belgian maker of cookware. They are best known for producing enameled cast-iron cookware. The company first manufactured their products in the town of Fresnoy-le-Grand in France in 1925, which are similar in function to a Dutch oven but with T-shaped handles. The Le Creuset Dutch oven is on display in the Smithsonian Institution's National Museum of American History in Washington, D.C. as a part of the recreation of the chef Julia Child's kitchen. It has been widely reported to be her favorite cooking pot, though specialist sources hold that it was the Dutch oven of Le Creuset's less-remembered competitor Descoware that was her real favorite. The company also makes many other types of cookware and bakeware, from fondue-sets to tagines.
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.
Corelle Brands, LLC is an American kitchenware products maker and distributor based in Downers Grove, Illinois.
Stanley Donald Stookey was an American inventor. He had 60 patents in his name related to glass and ceramics, some patents solely his and others shared as joint patents with other inventors. His discoveries and inventions have contributed to the development of ceramics, eyeglasses, sunglasses, cookware, defense systems, and electronics.
Corelle is a brand of glassware and dishware. It is made of Vitrelle, a tempered glass product consisting of two types of glass laminated into three layers. It was introduced by Corning Glass Works in 1970, but is now manufactured and sold by Corelle Brands.
Descoware is a discontinued brand of porcelain- or enamel-coated cast-iron cookware Among notable Descoware pots are dutch ovens. Although Descoware is now little-remembered, specialist sources hold that it was the favorite cooking ware of American cooking instructor and television personality Julia Child, more so than Le Creuset, whose association with the chef has been widely reported. Child regularly used Descoware on her television show The French Chef. The Smithsonian Institution's installation about Child's kitchen featured a large orange Descoware pot on top of Child's own stove.
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.
The Inspired Home Show, formerly known as the International Home + Housewares Show, is an annual housewares show staged at McCormick Place in Chicago and organized by the International Housewares Association. In 2008, the Show covered 785,000 net square feet (72,900 m2) of exhibit space. It is one of top 20 largest trade shows in the U.S. and in the top 10 in Chicago.
Pyroceram is the original glass-ceramic material developed and trademarked by Corning Glass in the 1950s. Pyroceram is an opaque, white, glass material, commonly used in kitchenware, glass stove tops, wood stove doors, etc.. It has high heat tolerance and low thermal expansion.
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.
Duralex is a French tempered glass tableware and kitchenware manufacturer located in La Chapelle-Saint-Mesmin in Loiret, France. Using a technique developed in the 1930s by Saint-Gobain, moulded glass is heated to 600 degrees Celsius then cooled very quickly, giving it an impact resistance that is twice superior to normal glass.
Visions is a brand of transparent stove top cookware created by Corning France and introduced to Europe during the late 1970s. In 1983, it was introduced in the United States and became the number one selling cookware set for a number of years. Visions is made of a transparent material belonging to the Pyroceram family of glass-ceramics. It is one of the few cookware lines that can be used on the range, in the oven, and under a broiler. It will withstand heat up to 850 °C (1,560 °F) with thermal traits similar to Corning Ware plus improved resistance to staining and the detrimental effects of acids and detergents. Visions is sold worldwide by Corelle Brands.
