The subject presents characteristics of glass materials, defines a difference between glass and glass melt and analyses their properties. The theory of glass melting, glass melting furnace, and theory of forming and annealing is given. Basic technological processes of automated glass production and processing are shown, including an overview of principles. Importance of treatment and processing of glass with new usable properties. The aim is to acquaint students with the basics of modern and automatic glass technology with an emphasis on used equipment and machines.
Student gets knowledge from these areas: General terms. Crystallic, liquid and glassy state of Glass. Glass constitution and structure. Properties. Raw materials for glass production, batch houses, preparation and charging methods of the batch, technology of glass melting, feeding and forming. Glass annealling. Decoration and finishing of glass. Experimental methods.
