Schott AG is an international manufacturing group of glass and glass-ceramics. The company is headquartered in Mainz, Germany and employs approximately 15,100 people worldwide.[1] All shares of Schott AG are solely held by the Carl Zeiss Foundation. The company reported sales worth 2.05 billion Euros in its fiscal year 2016/2017.[1]


In 1884, the glass chemist Otto Schott partnered with the congenial Ernst Abbe, Carl Zeiss and his son Roderich Zeiss, founded the Glastechnisches Laboratorium Schott & Genossen, which would later become Jenaer Glaswerke Schott & Genossen and then Schott AG. Schott developed and manufactured optical glasses for microscopes, telescopes and binoculars. Around 1890 Schott developed borosilicate glass products featuring a low thermal expansion coefficient and high chemical resistance very suitable for laboratory equipment, which was later marketed under the DURAN brand until the equity carve-out of these products to the DURAN Group in 2005. Glass-ceramics with even lower thermal expansion coefficient have been marketed since 1968 as Zerodur for telescope mirrors and other technical applications and Ceran for cooktops.

Erich Schott, the son of the company founder, took over the management of the plant in 1927. Chemist Marga Faulstich worked during this time for company Schott AG. The company suffered a severe blow at the end of World War II, when American troops brought its management and select experts over to West Germany. After the main production plant in Jena was expropriated by the communist government, Erich Schott opened a new plant in Mainz, the company's current headquarters, in 1952.

During Germany's division, there were two independent companies: the VEB Jenaer Glaswerk at the historical site, which would later be integrated into the combine VEB Carl Zeiss Jena, and the glassworks in Mainz that traded under the name Jenaer Glaswerk Schott & Gen. After the close cooperation of the two glassworks in the first years following World War II was stopped by the GDR in 1953, a dispute arose over the use of the company's name and logo, a square with a circle and the words Jena Glass with the superscript "er". The two parties finally reached an agreement in 1981, which allowed the West German company to use the name with the supercript and the square with a circle, while the East German company was permitted to use the term "Jenaer Glass." After the fall of the inner German border in 1989, the company based in Mainz acquired the East German company in Jena.[2]

Schott Solar[edit]

In 2008, Schott announced that it planned to produce crystalline photovoltaic cells and modules with a total of 450 MW annually. It also planned to produce thin-film PV wafers with a capacity of 100 MW.[3][4] In 2009, the company inaugurated a US$100 million solar manufacturing facility in Albuquerque, New Mexico, USA to build receivers for concentrated solar thermal power plants (CSP) and 64 MW of photovoltaic modules. They had already been making 15 MW of photovoltaics annually in Billerica, Massachusetts, until the factory was closed in 2009.[5] In June 2012, Schott announced that its Albuquerque plant would close down, laying off all photovoltaic cell manufacturing employees immediately and ramping down the remaining employees over the rest of the summer.[6] The company started operating in China since 2011,[7] with a large production.
