Historical information

Otto Schott, a chemist and glass engineer, had the vision of uniform production ie making glass items that would resemble one another. At the end of the eighteenth century, with most glass items still created by hand, the quality of output was still a guessing game. Schott was the first to render this an industrial certainty. 1884
Otto Schott, Ernst Abbe and Carl and Roderich Zeiss found the Schott & Associates Glass Technology Laboratory in Jena, Germany. Glastechnisches Laboratorium Schott & Gen was born. Production started in 1886. Original products included optical and thermometer glasses. The following year, a crucial discovery was made: borosilicate, a heat and chemically resistant glass. By it’s 25th year anniversary, the company had grown from an experimental glass factory into an internationally renowned manufacturer of optical and industrial glasses. Soon to be added was fiolax, tube-shaped glass used for vials, ampoules and syringes thus allowing the company to play a significant role in supplying Europe's nascent pharmaceutical industry.
