One of a Kind piece. Copper Firebrick Firebrick is from the old, hand-fired copper smelter of the Calumet & Hecla Mining Co., at Hubbell, Michigan. Hubbell is on the Keweenaw Peninsula, also known as the Copper Country. The old hand-fired smelter was built in 1885/86. But, by the end of the mid-1920's, furnaces were added. The smelter continued to operate until 1968. It was then closed and dismantled from 1968-1973. Over the years, the smelting process resulted in the firebrick adsorbing molten copper and other metals from the ore charge. When the smelter was torn down, local rock-hounds and lapidaries quickly discovered that the copper impregnated bricks made beautiful clocks, bookends and jewelry. What you have here is a rare piece of Michigan history.
