In the 1970s considerable expansion took place. In 1973 an area of about 100,000 m² was purchased in Zwiesel, on which a new plant was built. The annual turnover increased from 46 million DM in 1971 to 120 million DM in 1978. In 1979 the Schott Zwiesel Glaswerke AG employed about 1,900 workers and was one of Europe's largest cup glass ...
After the Second World War, from 1947 to 1948 production of FIOLAX glass tubing began in Mitterteich. In 1961: SCHOTT decided to extend and modernize Mitterteich as the location for glass tubing production. In 1969: representatives of what is now Schott Glaswerke and the Glaswerke Ruhr AG agreed upon the foundation of Schott-Ruhrglas GmbH.
The international glass code is based on U.S. military standard MIL-G-174, and is a six-digit number specifying the glass according to its refractive index n d at the Fraunhofer d- (or D 3-) line, 589.3 nm, and its Abbe number V d also taken at that line.
From 1911, Schott manufactured borosilicate glass tubing for the production of pharmaceutical ampoules and vials. [ 8 ] Schott Pharma was established as a standalone company in 2022 under the name Schott Pharma AG & Co.

There used to be an ISO standard (ISO/PAS IWA 8:2009) for glass clarity and freedom from lead and other heavy metals, but it was withdrawn. [13] Some producers of high-end wine glasses such as Schott Zwiesel have pioneered methods of infusing titanium into the glass to increase its durability and reduce the likelihood of the glass breaking. [14]
The millefiori technique involves the production of glass canes or rods, known as murrine, with multicolored patterns which are viewable only from the cut ends of the cane. [2] [9] A murrine rod is heated in a furnace and pulled until thin while still maintaining the cross section's design. It is then cut into beads or discs when cooled. [2] [9]
