Gold ruby glasses: influence of iron and selenium on their colour
2006 (English)In: Glass Technology, ISSN 0017-1050, Vol. 47, no 4, 112-120 p.Article in journal (Refereed) Published
Colour development of gold ruby alkali silicate glasses, when various elements are added to the batch, has been investigated. Elements used in the study are selenium, iron, tin, lead, antimony, cerium, titanium and bismuth. The colours are presented and compared by their Lab coordinates. Among the elements selenium and iron are found to be important, and the role of these elements in colour development is discussed. Thermodynamic calculations show that important oxidation states are Fe2+ for iron and Se-0 and Se2- for selenium, and that higher melting temperature improves the colour, as it affects the oxidation states of both Fe and Se.
