Abstract: The invention relates to a process for producing high-strength construction and decoration materials which resemble natural stone, are in the form of panels and are used for cladding facades, walls and floors, both indoors and outdoors, from mixtures of broken glass, mineral components and finely divided additives, with a specified composition. A sintering aid, in the form of a solution of metal oxychlorides or metal alkoxides or tetrachlorides, preferably titanium tetrachloride, is added to the mixture, which is then introduced into a heat-resistant mould. In this mould, the mixture is subjected to a conventional sintering operation. The sintering aid which has been added makes it possible in particular to reduce the maximum sintering temperature and to improve the quality of the surface considerably.
