The Durability of Lime-soda Glasses

JSGT 1919 V03 T228-T237 (14 pages including 4 of plates)

The introduction of the new types of automatic machinery has called for a moderately soft glass. This condition has been obtained by decreasing the amount of lime and increasing correspondingly the amount of soda present. It is essential to determine once for all how far this softening process may proceed, so as to set the limits between which durable commercial glasses may be prepared. This is the whole object of the investigation recorded in this paper.
