Thermal toughening The different viscosity characteristics of the white flashed layer and the base glass have to be considered and to eventually comply with the requirements of safety glass need to be checked.As a result of this heat treatment, the transmittance may vary whilst at the same time the diffusion indicatrix changes accordingly.

Because both types of glass do have a different behavior in resistance of water, acids and alkaline solutions, the usual classification cannot be made. You can say that it is largely insensitive to the action of water, acids, alkalis and salt solutions (with the exception of hydrofluoric acid).
