In the Rogaška glass factory, the knowledge comes from almost 350 years of tradition from the areas of Trebuša, Pohorje, and Kozjansko, where the early glassworks were to be found.
After the blossoming of glass-making in the 18th and 19th century and later on near the decline of the melting furnaces Viljem Abel, the owner of Joint glass factories, built the glass factory Rogaška in the year 1926, which is today one of the biggest European producers.
In Rogaška one can also join a guided group tour of the factory and the production of the unique products of glass masters, which are made by blowing the glass into different shapes.
