PYREX 805 A-14 1 cup/8 oz Measuring Cup Condition: This vintage 1970s PYREX measuring cup is used in good condition. The measurement lines are faded but still visible. The measuring cup has no chips, but has light scratches from use.Capacity: 1 cup / 8 fluid ounces / 250 mLMaterial: GlassMade in USAThis vintage PYREX 508 measuring cup has the classic D handle. It has United States customary volume measurements on one side with cup measurements and fluid ounce measurements (1/4, 1/3, 1/2, 2/3, 3/4, 1 cup markings). The opposite side has metric measurements up to 250 mL. This style of measuring cup was first released in 1975. It was available until 1982. The measuring cup was made in Corning, NY (USA). Pyrex (trademarked as PYREX and 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 to include ware products made of soda-lime glass and other materials. In 1998, the products division of Corning Inc. responsible for the development of PYREX spun off from its parent company as Corning Consumer Products Company, subsequently renamed Corelle Brands. Corning Inc. no longer manufactures or markets consumer products, only industrial ones. Instant Brands continues to license the pyrex (lowercase) trademark for their tempered soda-lime glass line of kitchenware products and related accessories sold in the United States, South America, and Asia. In Europe, Africa, and the Middle East, the PYREX (all uppercase) trademark is licensed by International Cookware for bakeware that has been made of borosilicate and soda-lime glass, stoneware, metal plus vitroceramic cookware. In the past, the brand name has also been used for kitchen utensils and bakeware by other companies in regions such as Japan and Australia. HistoryBorosilicate glass was first made by German chemist and glass technologist Otto Schott, founder of Schott AG in 1893, 22 years before Corning produced the Pyrex brand. Schott AG sells the product under the name “Duran”. In 1908, Eugene Sullivan, director of research at Corning Glass Works, developed Nonex, a borosilicate low-expansion glass, to reduce breakage in shock-resistant lantern globes and battery jars. Sullivan had learned about Schott’s borosilicate glass as a doctoral student in Leipzig, Germany. Jesse Littleton of Corning discovered the cooking potential of borosilicate glass by giving his wife Bessie Littleton a casserole dish made from a cut-down Nonex battery jar. Corning removed the lead from Nonex and developed it as a consumer product. Pyrex made its public debut in 1915 during World War I, positioned as an American-produced alternative to Duran. A Corning executive gave the following account of the etymology of the name “Pyrex”: The word PYREX is probably a purely arbitrary word which was devised in 1915 as a trade-mark for products manufactured and sold by Corning Glass Works. While some people have thought that it was made up from the Greek pyr and the Latin rex, we have always taken the position that no graduate of Harvard would be guilty of such a classical hybrid. Actually, we had a number of prior trade-marks ending in the letters ex. One of the first commercial products to be sold under the new mark was a pie plate, and in the interests of euphonism the letter r was inserted between pie and ex and the whole thing condensed to PYREX. In the late 1930s and 1940s, Corning also introduced other products under the Pyrex brand, including opaque tempered soda-lime glass for bowls and bakeware, and a line of Pyrex Flameware for stovetop use; this aluminosilicate glass had a bluish tint caused by the addition of alumino-sulfate. In 1958 an internal design department was started by John B. Ward. He redesigned the Pyrex ovenware and Flameware. Over the years, designers such as Penny Sparke, Betty Baugh, Smart Design, TEAMS Design, and others have contributed to the design of the line. Patterned casseroleCorning divested itself of the Corning Consumer Products Company (now known as Corelle Brands) in 1998 and production of consumer Pyrex products went with it. Its previous licensing of the name to Newell Cookware Europe remained in effect. France-based cookware maker Arc International acquired Newell’s European business in early 2006 to own rights to the brand in Europe, the Middle East and Africa. In 2007, Arc closed the Pyrex soda-lime factory in Sunderland moving all European production to France. The Sunderland factory had first started making Pyrex in 1922 In 2014, Arc International sold off its Arc International Cookware division which operated the Pyrex business to Aurora Capital for its Resurgence Fund II. The business now operates as International Cookware. CompositionOlder clear-glass Pyrex manufactured by Corning, Arc International’s Pyrex products, and Pyrex laboratory glassware are made of borosilicate glass. According to the National Institute of Standards and Technology, borosilicate Pyrex is composed of (as percentage of weight): 4.0% boron, 54.0% oxygen, 2.8% sodium, 1.1% aluminum, 37.7% silicon, and 0.3% potassium. Beginning in the 1980s, production of clear Pyrex glass cookware manufactured by Corning (and later Instant Brands, after the consumer division was spun off and renamed) was shifted to tempered soda-lime glass, like their opal bakeware. This change was justified by stating that soda-lime glass has higher mechanical strength than borosilicate—making it more resistant to physical damage when dropped, which is believed to be the most common cause of breakage in glass bakeware. Also, it is cheaper to produce and more environmentally friendly. However, its thermal shock resistance is lower than borosilicate’s, leading to potential breakage from heat stress if used contrary to recommendations. Since the closure of the soda-lime plant in England, European Pyrex has made solely from borosilicate. Use in telescopesBecause of its low expansion characteristics, Pyrex borosilicate glass is often the material of choice for reflective optics in astronomy applications. In 1932, George Ellery Hale approached Corning with the challenge of fabricating the 200-inch (5.1 m) telescope mirror for the California Institute of Technology’s Palomar Observatory project. A previous effort to fabricate the optic from fused quartz had failed, with the cast blank having voids. The mirror was cast by Corning during 1934–1936 out of borosilicate glass. After a year of cooling, during which it was almost lost to a flood, the blank was completed in 1935. The first blank now resides in the Corning Museum of Glass. (Wikipedia)
