Conventionally, little chemical adjustments are made to the slag prior to its processing for subsequent use or disposal. However, recent attempts have looked into modifying the chemical composition of slag while hot, to render its chemistry and properties suitable for high-value products or recovery of minerals/metals from slag [11, …

the high glass contents could be maintained at a larger scale. As atomization is scaled-up, the surface area of the SAPs decreases in relation to the slag amount processed and this decreases the slag cooling rate. Lower slag cooling rates might lower the glass content of the atomized slag product, and thus reduce its viability as a cement substi-

Slag glass was first created in England in the 1880s as an opaque brown with white streaks from iron slag. Sowerby, a popular pressed glass manufacturer in the UK during this time frame, was the first manufacturer to start producing slag glass. They started with brown glass, but also produced purple, yellow, green, and blue.
