Abstract
In the manufacture of glass, sodium sulphate has a definite
place as a raw material. For a long time it was being used as
the chief source of alkali for its cheapness. As ammonia-soda
process proved to be a commercial success, sod1 ash succeeded
salt cake in the manufacture of glass as it was easier to use,
yielded more colourless glass and reacted more quickly with
silica. In the last few years, except for a few cases such
as window glass or green bottle glass, saltcake is used only
as a minor constituent of the batch. After the last war it is
again being used on a large scale in Germany due to the
shortage of soda ash and in Russia since it is available in
huge quantities as a surface mineral.
