The cluster-plus-glue-atom model is introduced to model silicate glasses in the form of a molecule-like supercluster unit {M2O3}n{Si2O4}16-n as the composition carrier, where M represents an average trivalent cation, in correspondence to the coordination numbers of 3 to 4 according to the random network model. Soda-lime-silicate, aluminosilicate, and borosilicate glasses of historical importance are addressed. Classical soda-lime-silica glasses as exemplified by 1:1:6 standard glass and modern aluminosilicate glasses such as Corning Gorilla glasses of the first generation generally satisfy trivalent-cation formulas {M2O3}16. Borosilicate glasses are characterized by extra quadrivalent {Si2O4}, as exemplified by Corning E-glass and Schott thermometer glass formulated by {M2O3}12{Si2O4}4, Schott utensil glass by {M2O3}16{Si2O4}6, and Corning Pyrex and Schott Welsbach chimney glasses by {M2O3}7{Si2O4}9.
