History of the HVG
HVG can reflect upon a history of more than 80 years. On 8 July 1920, the »Wärmetechnische Beratungsstelle der Deutschen Glasindustrie« (WBG) was established by the Association of the German glass manufacturers. In 1936, the »Hüttentechnische Vereinigung der Deutschen Glasindustrie« (HVG) originated from the WBG due to the extension of the activities to the entire field of the glass technology.
The driving force behind the creation of this consultancy agency was the scarcity of coal after World War I and the resultant lack of generator gas needed for heating the glass melting furnaces. In the early days, the activities of the agency comprised the recording of the heat-technical indexes by measuring techniques, the listing of heat balances and the optimisation of the glass melting process with the goal of an efficient use of fuel.
In the course of time, further test methods and investigations were added, complemented by teaching courses for supervisors and technicians in the glassworks as well as contact to relevant research institutes and universities.

An ancient method of window glass production is the manufacturing of bullions. The upper picture shows the flaring of a blown out and opened glass sphere before a pot arch. Through rotation the hot and soft material is flung with the blowing iron (lower picture), so that a flat pane is produced that can be laid down in a special device before it is annealed in the annealing furnace in a slow and controlled way.

HVG-DGG Chronicle
A detailed »history of HVG and DGG« from 1920 to 1985 is presented in a German language article by Professor Wolfgang Trier (HVG/DGG director from 1961 to 1985). Professor Helmut Schaeffer (HVG/DGG director from 1985 to 2003) treated the HVG/DGG history from 1985 to 1992.
