Glass surfaces are characteristic for the façade appearance and contribute significantly to the authenticity of architectural monuments. The material glass is considered an important testimony of its time. Depending on the
manufacturing process, it differs both in surface and in material composition. The period of high modernism (ca. 1880-1970) overlapped with the technical developments of the industrial revolution, which led from manual to industrial production. The further development of manufacturing processes
as well as the dimensions and qualities of glass thus shaped the development of
glass constructions, which had to become increasingly slender over time in order
to ensure a high degree of transparency. Nowadays, historic windows are often
replaced by new glazings made of float glass, which can cause the authentic character of buildings to be lost. A research team from the Technische Universität Dresden and the University of Bamberg are examining glass
and its construction in detail in the period from around 1880 to around 1970. They define the living character of industrially manufactured
glass from the time before the introduction of float glass as an authentic and style-forming feature of the era. The present work presents
the investigation of historical glass and glass constructions in a suburb of Dresden. It was determined how much the historic glassis
currently still present in the study area . From the results and the evaluation, the importance of historic glass constructions is deduced for engineers, planners and monument conservators, who can contribute a great deal
to the preservation of historic glazing.
