Leland blue slag glass is a waste byproduct from the iron ore smelting process used by the Leland Lake Superior Iron Company based in the town of Leland, Michigan.
Beech and maple hardwood based charcoal with local limestone flux was used to refine the ore, with the slag consisting of iron ore impurities dumped into Lake Michigan. About 2% of the slag has the blue color favored by collectors.
Leland blue slag glass is valued by collectors, jewelers, and lapidarists. It’s often used to make beautiful jewelry.
