Hard glass which is used for making laboratory glass wares is a mixture of sodium borosilicate and aluminium borosilicate
Glass is decolorized during its manufacture by adding antimony oxide, manganese dioxide or arsenic oxide
Ordinary glass is represented chemically by Na2O . CaO . 6SiO2
Red color is imparted to glass by addition of arsenic oxide
