THE DETERMINATION OF CARBON IN GLASSES COLOURED BY CARBONACEOUS MATTER

Abstract

A method is described for the determination of the carbon content of glasses. The effect of carbon content on the colour of the glass produced was investigated with reference to a parent glass SiO₂ 72%, CaO12, Na₂O 16 (when the carbon was added to the batch in the form of graphite, carbon black and cane sugar, both without and in the presence of sodium nitrate)
