Duran Group is a world-leading manufacturer of borosilicate glass. Borosilicate glass was invented by Mr. Otto Schott in 1887, and the DURAN® trademark was registered in 1938. Duran Group has a complete industrial chain from glass raw material melting to glass forming and processing, and has production bases in Germany, the UK, and Croatia.

Since then, the logo of Schott Duran® will be replaced by the logo of Duran®, and the product quality will remain unchanged.
