Superfest, also known as CV-Glass[1] or Ceverit[2] was a brand of drinking glass produced in East Germany from 1980 to 1990[2]. The glasses were made of a chemically strengthened glass[3] making them significantly stronger than those made using conventional soda–lime glass, giving Superfest glasses a reputation for being unbreakable.
History[edit]
In 1973, the Zentralinstitut für anorganische Chemie (Central Institute for Inorganic Chemistry) in East Germany created the Abteilung Glasstrukturforschung (Glass Structure Research Department) to investigate, among other things, the substitution of sodium ions on glass surface for larger potassium ions.[3]
On August 8, 1977, a four-person team led by the scientist Dieter Patzig was awarded a patent for the process.[4]. The Council of Ministers of East Germany secured funding to put the new glass into production. In 1979, a new production hall was built specifically for production in the VEB Sachsenglas Schwepnitz factory. Production at the new facility began in May of 1980[1]
Superfest glass failed to gain traction outside of East Germany, with many citing planned obsolescence as the motivating factor.[2] After the German reunification, the unified government was not interested in producing glasses and the factory could not find a buyer interested in continuing production. The last glass was produced on July 1, 1990.[2]
