Research and Common Sense in the Glass Industry
JSGT 1956 V40 T301-T318
It is now appreciated that the formation of glass is not the simple solution of the more refractory by the more fusible constituents of the batch. Good workable glasses can be produced by founding at temperatures well below that of the melting point of the most fusible constituent, and it is well known that glass-making is a process involving reactions in the solid state and of eutectic formation.
