The 92nd Annual Meeting of the German Society of Glass Technology (DGG) is held in conjunction with the Annual Meetings of the Czech Society of Glass Technology (CSS) and the Slovak Society of Glass Technology (SSS). The joint conference takes place from 28th to 30th May, 2018 in the city of Bayreuth, Germany. 104 oral and poster contributions cover a wide scope of topics reaching from the fundamentals of the glassy state and amorphous materials to energy applications of glass topics related to health, medical, and biological applications as well as optical materials and devices, and finally to glass production technology.

The city of Bayreuth is a focus of culture. The annual Richard Wagner opera festivals enjoy highest reputation worldwide. The tradition started at the lifetime of the great composer already. The Margravial Opera House, still present today, turned out to offer far too little space for the large number of opera friends attracted. So, since 1873, the festival has been taking place in the then built Festival Theatre on the Green Hill. From July to August 2018, seven Wagner operas will be presented, with an expected number of 60,000 visitors.

But the city of Bayreuth has more to offer. Do not miss to visit the New Castle, the beautiful scenery of the Eremitage, or one of its 25 museums (among them, of course, the Richard Wagner Museum – Haus Wahnfried, the Franz Liszt Museum, or the Prehistorical Museum). Do not miss to enjoy the typical Franconian cuisine and to test the results of its beer brewery history.

The University of Bayreuth hosts a faculty of engineering comprising a department devoted to glass science and technology. It is led by Prof. Thorsten Gerdes, the local academic host of the conference. He and his staff will lend their support to the local organization of the event. His department is a vital part of a Bavarian glass network comprising the Fraunhofer Institute of Silicate Science, Würzburg, running one of its many spin-offs in Bayreuth, as well as the universities and universities of applied science in Erlangen, Nürnberg, Regensburg, Deggendorf, Coburg, Hof, the Glass School in Zwiesel, and the Center of Technology in Spiegelau. The so-called Glass Road extending throughout Bayreuth’s Southern neighbor region of Oberpfalz hosts a large number of glass producers, glass workshops, and glass museums.

It may be less well known that the city of Bayreuth also hosts the German-Czech Society. It is an enjoyable coincidence that this conference held in conjunction with our neighbors from the Czech and Slovak Republics takes place just here. Glass science and technology has been a traditional focus in our neighbor countries, enjoying high recognition worldwide. So, we may look forward to a considerable reinforcement of the conference.

Finally, the organizers want to express sincere gratitude to the manifold contributors to this event, and to the numerous sponsors. Special thanks go to the symposia chairs who did their very best in composing and organizing the symposia programmes.
