Water-resistance of the mold surface of float glass

The results of studies of the water resistance of float glass from different manufacturers (both original and tempered) are presented. It was revealed that for heat-absorbing and colorless float glass there is an asymmetry in the water resistance of molded surfaces: the water resistance of the lower surface is better than the upper one, by about 2 times. It is shown that in the process of tempering the water resistance of glass decreases, while the asymmetry of the water resistance of the surfaces remains. Based on the results obtained, it was concluded that the water resistance of float glass depends on its chemical composition and technological parameters of production.
