Course detail

Glass Technology

FAST-NJA033Acad. year: 2022/2023

The aim of the new course master study program M is to introduce students with the theoretical foundations of the glass melting process as the most important technologies for glass processing especially with regard to the type used in glass furnaces. Attention will also be devoted to testing the properties of glasses and corrosion. An essential part of teaching is also excursion into the production of glass.
