Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.
Glass beads composed of soda lime glass are essential for providing retroreflectivity in many kinds of road surface markings. [1] Retroreflectivity occurs when incident light from vehicles is refracted within glass beads that are imbedded in road surface markings and then reflected back into the driver's field of view.

In addition to about 75% SiO 2 and 8–12% B 2 O 3, these glasses contain up to 5% oxides of alkaline earth metal and alumina (Al 2 O 3). This is a subtype of slightly softer glasses, which have thermal expansions in the range (4.0–5.0) × 10 −6 K −1. [11] This is not to be confused with simple borosilicate glass-alumina composites.

An example batch calculation may be demonstrated here. The desired glass composition in wt% is: 67 SiO 2, 12 Na 2 O, 10 CaO, 5 Al 2 O 3, 1 K 2 O, 2 MgO, 3 B 2 O 3, and as raw materials are used sand, trona, lime, albite, orthoclase, dolomite, and borax. The formulas and molar masses of the glass and batch components are listed in the following ...
