slagk
Slagk is a term used in geology and industrial metallurgy to describe a glassy, slag-derived material that resembles natural glass but originates from metallic byproducts. The term is not formally recognized as a mineral species by major databases, and its use varies between disciplines; some authors apply slagk to natural glass formed from quenched slag, while others use it for synthetic glasses produced from slag compositions.
They typically contain iron and silica-rich matrices, with aluminum oxide and trace metals from the original
Formation and occurrence: Natural slagk-like glass can form when molten slag is rapidly cooled and quenched,
Uses and significance: Slagk is of interest in archaeometallurgy as an indicator of past metalworking activity,
