The reasons for the increased tendency to foaming of iron-containing glass melts are revealed, depending on the composition, concentration of iron oxides, and the cooking medium. Recommendations for their elimination are given. It is shown that foam in iron-containing silicate melts is formed by the interaction of a ferritized melt with quartz. Tab. 2, ill. 4, bibliography: 9 titles.

The effect of the content of water vapor and oxygen in the atmosphere of a tin molten bath on the microhardness of the surface layers of float glass from various enterprises in Russia and Ukraine has been studied. It is shown that an increase in the water vapor content does not lead to a significant decrease in the surface microhardness. At the same time, an increase in the concentration of molecular oxygen causes a decrease in the surface resistance to the action of abrasive particles. Il. 1, bibliography: 5 titles.

The issues of mathematical modeling of the process of melting lead-containing glasses used in the production of ceramic paints are considered. On the basis of laboratory studies, the stages of physicochemical transformations in the charge and during the production of glass melt have been established. Industrial experiments made it possible to establish the optimal temperature conditions for the processes of obtaining acid-resistant glasses. This made it possible to reasonably calculate the gas consumption during glass melting. Il. 3, bibliography: 6 titles.
