This is a great “recycled” material from northern Michigan. It is actually a glass slag which is the byproduct from smelting iron ore which was mined in the upper peninsula and brought down to the lower peninsula for refining. The slag was waste material that was dumped into lake Michigan. Used in railroad beds and even foundations of buildings in the late 1800’s. The blue is quite rare and is the most highly prized color.
