Glass is a non-crystalline solid that is often transparent, brittle and chemically inert. It has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics.
Laboratory glassware refers to a variety of equipment used in scientific work, and traditionally made of glass. Glass can be blown, bent, cut, molded, and formed into many sizes and shapes, and is therefore common in chemistry, biology, and analytical laboratories. Many laboratories have training programs to demonstrate how glassware is used and to alert first–time users to the safety hazards involved with using glassware.
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.
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.
Vycor is the brand name of Corning's high-silica, high-temperature glass. It provides very high thermal shock resistance. Vycor is approximately 96% silica and 4% boron trioxide, but unlike pure fused silica, it can be readily manufactured in a variety of shapes.
Glass tubes are mainly cylindrical hollow-wares. Their special shape combined with the huge variety of glass types, allows the use of glass tubing in many applications. For example, laboratory glassware, lighting applications, solar thermal systems and pharmaceutical packaging to name the largest.
Schott AG is a German multinational glass company specializing in the manufacture of glass and glass-ceramics. Headquartered in Mainz, Germany, it is owned by the Carl Zeiss Foundation. The company's founder and namesake, Otto Schott, is credited with the invention of borosilicate glass.
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 in the United States. The brand was later spun off with the sale of the Corning Consumer Products Company subsidiary.
Friedrich Otto Schott (1851–1935) was a German chemist, glass technologist, and the inventor of borosilicate glass. Schott systematically investigated the relationship between the chemical composition of the glass and its properties. In this way, he solved fundamental problems in glass properties, identifying compositions with optical properties that approach the theoretical limit. Schott's findings were a major advance in the optics for microscopy and optical astronomy. His work has been described as "a watershed in the history of glass composition".
Iittala, founded as a glassworks in 1881, is a Finnish design brand specialising in design objects, tableware and cookware. Iittala's official i-logo was designed by Timo Sarpaneva in 1956.
Arc Holdings is the holding company of the Arc Group, specializing in the design and manufacturing of glass tableware. The Arc Group markets its collections in France and exports them abroad under the registered trademarks Luminarc, Arcopal, Cristal d’Arques Paris, Arcoroc and Chef&Sommelier. It also designs products for the private label and B2B markets.
Zwiesel Kristallglas AG is a manufacturer of crystal glass located in Zwiesel, Germany.
Glass production involves two main methods – the float glass process that produces sheet glass, and glassblowing that produces bottles and other containers. It has been done in a variety of ways during the history of glass.
SCHOTT AG Site Mitterteich in Mitterteich, Germany is one of the leading manufacturers of glass tubing. With more than 1000 employees, it is one of the largest employers in the Tirschenreuth district as well as in the whole Northern Upper Palatine. The Mitterteich site is the largest location of the Business Segment Tubing of Schott AG. Other locations are in Mainz, Germany, Rio de Janeiro, Brazil, and Vadodara, India.
An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids, and sometimes to their melting point. Evaporating dishes are used to evaporate excess solvents – most commonly water – to produce a concentrated solution or a solid precipitate of the dissolved substance.
Early American molded glass refers to glass functional and decorative objects, such as bottles and dishware, that were manufactured in the United States in the 19th century. The objects were produced by blowing molten glass into a mold, thereby causing the glass to assume the shape and pattern design of the mold. When a plunger rather than blowing is used, as became usual later, the glass is technically called pressed glass. Common blown molded tableware items bearing designs include salt dishes, sugar bowls, creamers, celery stands, decanters, and drinking glasses.
Tritan is a transparent glass-like plastic originally developed by the German Schott Zwiesel AG in 2002 together with University of Erlangen–Nuremberg. Its name is derived from Titanoxide. In 2012, the Zwiesel Kristallglas AG introduced Tritan Protect.
Marga Faulstich was a German glass chemist. She worked for Schott AG for 44 years. During this time, she worked on more than 300 types of optical glasses. Forty patents were registered in her name. She was the first woman executive at Schott AG.
Bormioli Rocco is an Italian manufacturer of household goods now operating under the name Bormioli Luigi SpA. The company is one of the world's leading suppliers of tableware and glassware. Founded in 1825 in Fidenza, Bormioli Rocco produces glassware and plastic containers for home use, as well as containers for pharmaceutical use.
DURAN is a brand name for the internationally defined borosilicate glass 3.3 produced by the German company DURAN Group GmbH since 2005 under license from the Schott AG, which was the first to develop it, and which sold it from 1893 until the equity carve-out of the DURAN Group in 2005. Because of its high resistance to heat and temperature changes, as well as its high mechanical strength and low coefficient of thermal expansion, DURAN, which Pyrex from Corning is similar to, is not only used for laboratory devices but also in cathode ray tubes, transmitting tubes, and speculums.
