The afterproduct of sand blasting is called silica dust and can cause silicosis in workers after prolonged inhalation. Because of this, sand blasting is heavily regulated. Conversely, glass bead blasting is much safer because the beads do not produce a silica dust and are lead free.
Glass disease, also referred to as sick glass or glass illness, is a degradation process of glass that can result in weeping, crizzling, spalling, cracking and fragmentation. Glass disease is caused by an inherent instability in the chemical composition of the original glass formula. Properties of a particular glass will vary with the type and proportions of silica, alkali and alkaline earth ...
