Behavior of Zinc Selenite, Calcium Selenite and Metallic Selenium as Decolorizing Agents in Flint Glass Production

Abstract:

Zinc selenite, calcium selenite and metallic selenium have been consecutively introduced as decolorizing agents in a flint glass production. The selenium concentration in the glass has been measured by wet-chemical analysis, optically by the evaluation of the cielab a-value and electrochemically by means of a voltammetric sensor. All measuring techniques showed the highest selenium retention for calcium selenite followed by zinc selenite and the least retention using metallic selenium. The best reproducibility is achieved using zinc selenite while both calcium selenite and metallic selenium provide only poor reproducibility.
