Colour Development In Copper Ruby Alkali Silicate Glasses. Part 2. The Effect Of Tin (Ii) Oxide & Antimony (Iii) Oxide

The effect of Sb3+ & Sn2+ during the heat treatment of copper ruby alkali silicate glasses is investigated. The reducing power of SnO & Sb2O3 with respect to Cu is investigated & it is concluded that SnO has the strongest reducing capability. When Cu2O & SnO concentrations are low, minor additions of Sb2O3 have an observable impact on colour development & absorbance, as thin pieces of glass develop a bluish tint & a larger shift towards longer wavelengths is observed in UV/vis spectra. The differences in colour & spectra are suggested to be caused by differences in size of the colour forming agent, Cu metal particles.
