What is copper infused firebrick?
Copper firebrick comes from Michigan's Upper Peninsula. The copper mining industry there lasted from the about 1845 to 1960’s. When the smelters were dismantled they discovered that copper had infused into the smelter brick, creating copper firebrick. The copper had infused into the firebrick replacing everything except the silica(quartz) in the brick. The brick from each smelter looks different. Some have white brick flecks while some have black flecks, and the appearance of the brick can differ depending on the location of the brick in the smelter.
