Colour Development In Copper Ruby Alkali Silicate Glasses. Part 1. The Impact Of Tin (Ii) Oxide, Time & Temperature

The development of the red colour in copper ruby alkali silicate glasses has been studied by means of ultraviolet/visible spectroscopy, TEM & EXAFS. The results show that both red & slightly overstruck, brownish glasses the colour is due to clusters of metallic copper. Before striking non-coloured glasses contain mainly cuprous ions, Cu+. Tin acts as a reducing agent but also has an accelerating effect on colour development.
