Crystal formation is a function of both the chemical composition of the melt and its cooling rate. Silica rich blast-furnace slag vitrifies (forms a glassy phase) easily when it is rapidly cooled. Steel slag has a lower silica content than blast-furnace slag and, hence, steel slag seldom vitrifies even when rapidly cooled.
