The smelters continued to operate until 1968. They were closed and dismantled between 1968-1973. Over the years, the smelting process resulted in the firebrick absorbing molten copper and other metals from the ore charge.  When the smelters were torn down, local rock-hounds and lapidaries quickly discovered the copper impregnated bricks made beautiful clocks, bookends and jewelry.\u003cbr\u003eThis is a rare piece of Michigan history.\u003cbr\u003e\u003c\/p\u003e","brand":"KGG- Dollar Bay","offers":[{"title":"1lb","offer_id":47561402515668,"sku":null,"price":35.0,"currency_code":"USD","in_stock":false},{"title":"2lb","offer_id":47561402548436,"sku":null,"price":70.0,"currency_code":"USD","in_stock":false},{"title":"3lb","offer_id":47561402581204,"sku":null,"price":105.0,"currency_code":"USD","in_stock":false},{"title":"4lb","offer_id":47561402613972,"sku":null,"price":140.0,"currency_code":"USD","in_stock":false},{"title":"5lb","offer_id":47561402646740,"sku":null,"price":175.0,"currency_code":"USD","in_stock":false},{"title":"6lb","offer_id":47561402679508,"sku":null,"price":210.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/wholesale.copperconnection.com\/products\/copper-firebrick-decorator-slab-copy","provider":"Keweenaw Gem \u0026 Gift - WS","version":"1.0","type":"link"}
