METHOD OF PRODUCING GLASS ARTICLES

摘要

The invention relates to a method of producing glass articles. The inventive method consists in melting oxides and other raw materials in a glass melting furnace in order to produce molten glass and conveying the molten glass from the melting furnace to moulds in which the articles are formed as the glass solidifies. The invention is characterised in that it comprises the following steps consisting in: supplying the glass melting furnace with sludge from wastewater treatment plants, comprising determined concentrations of oxides; and adding suitable amounts of corresponding compounds to the melting furnace in order to obtain a determined total end composition of the aforementioned oxides, such that the oxide composition of the resulting article corresponds to that of a rock having a low melting temperature and low viscosity within the working temperature range of glass.
