The Colour and Constitution of Glass

JSGT 1947 V31 T100-T104

The bonding of the atoms in glass is considered from the point of view of the electronic theory of valency. It is shown that increased acidity of a glass is equivalent to increased oxidising power. The suggestion is made that all metals may be considered as being capable of participating in the maintenance of the vitreous continuous network, the importance of the co-ordinate link being stressed. The colours exhibited by cobalt in glass are related to the degree of covalent character of the cobalt atoms.
