Copper Firebrick 01-4000

Locally Made from Copper Firebrick. Firebrick is from the old, hand-fired copper smelter of the Calumet & Hecla Mining Co., at Hubbell, Michigan. The smelter was built in 1885/86 and operated until 1968. It was then closed and dismantled from 1968-1973. Over the years, the smelting process resulted in the firebrick absorbing 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. 3.25" x 4.25" x 1.75"
