AB  - Homogenization and heat treatment control plays a primary role in the production of lead glasses. Homogenization processes are applied in different ways. One of the important methods which is also industrially practical for other glass systems is fritting that is the process of melting and quenching of molten materials to form small glass particles. In the current research, the effect of homogenization and heat treatment on the thermal and physical properties of lead glasses is investigated. The fritting procedure is applied six terms for lead glass composition and the effect of fritting on thermal, physical, chemical resistance and homogeneity of glass are studied. While the effects of 3 times of heat treatment on these properties are studied. Finally, the result of micro-structural analyses of glass specimens are presented showing that an increase of the fritting period has an undesirable influence on different properties of glass samples and this process would be used in joint considering of other effected parameters.
