Abstract The optical absorption and infrared (IR) spectra of mixed alkali silicate glasses in the system 3SiO2–(1−x)Na2O–xK2O+2.5–20 g of TiO2 were measured. Absorption bands due to Ti3+ ions, at 500 and 570 nm, were observed in the spectrum of Na2O-free glasses. The intensities of such bands were followed with the variation in TiO2 content from 2.5 to 20 g (per 100 g of glass). The incorporation of titanium oxide as Ti3+ in the Na2O-free glass, conferring a violet hue to it, was explained on the basis of the acidity–basicity character of the glass. The IR measurements have been used to explore the structural changes throughout the compositional variations.
