What is Slag Glass? Price Guide and History

Slag glass gets its name from slag, or the byproduct of steel production. When iron ore is smelted in that process, the remaining residue is a glass-like, often glossy material that takes on different colors depending on the minerals and elements present in the iron.

Ancient Metallurgy

Iron worked in this way and containing only negligible carbon is called "wrought iron," and its production is necessarily quite time-consuming. On the other hand, iron with high carbon content and as a result with a lower melting point could be melted and molded and is referred to as "cast iron."

When is Iron discovered? | Updated 2021 Properties of Steel

Until then iron was obtained by mixing iron with slag, with some carbon or carbides, then forged, removing the slag and oxidizing the carbon, thus creating the product with a shape. The iron thus obtained had a very low carbon content and could not easily be hardened by cooling it in water.

17) Iron Staining & Gossans. Not all veins produce much quartz. Gold-bearing veins can consist of calcite or mostly sulfides—which often weather into iron-stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.
