SPECIAL REPORT/GLASS: Identifying Glass Defects

Common glass defects include bubbles, stones, knots, cords and scratches. One unusual stone defect in a pattern glass was recently discovered, and a scrupulous methodology was necessary to investigate its source. Numerous plate glass samples with white-colored stone defects were received for analyses (see Figure 1).

Silica sand - an overview | ScienceDirect Topics

Sand (silica or silicon dioxide) melts at 1710 °C, and sodium carbonate melts at 851 °C. These ingredients along with lime, CaO, make up a common type of glass known as soda-lime glass because it contains soda, lime, and silicon dioxide (Na 2 CO 3, CaO, and SiO 2 ) with the composition being about 25%, 12.5%, and 62.5%, respectively.

The texture may vary from shiny, where the glass is balanced, to matt where the excessive flux oxides may form visible, possibly lumpy, crystals. Too much silica will create a stiff, white and densely opaque glass with an uneven surface. It will be glossy in spots, but the suspended silica can form crystals producing harsh dry surfaces.
