Solid Copper Upper Peninsula
Solid Copper Upper Michigan Shape. Sand cast in our foundry. Measures: 5 1/4"L x 3"H x 1/2"thick. Sand Casting is made from pouring molten Michigan Native Copper at 2200 degrees F onto open-faced sand cast molds. When they cooled, a green or turquoise colored chemical patina is applied then highlights are buff polished to expose the glowing solid copper underneath. The items are sprayed with a laquer to preserve the finish and to prevent the copper from tarnishing.
