This unique and beautiful item is made of authentic slag glass that has been found near the furnace mill. In Tennessee. The glass features a stunning array of multi shades of blue, making it a perfect addition to any garden or outdoor living space. Beautiful piece for a aquarium, terrarium, bookshelf or break it up for smaller pieces for jewelry, wine stopper anything you can think of!!!

Slag glass is the by product from the steel process, once the iron is melted this is left over and poured in a nearby river, once it hits the water these pieces are formed. Fascinating!! And beautiful no 2 pieces are the same. Each one is unique.
