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":".3lb","offer_id":47649874182356,"sku":null,"price":11.0,"currency_code":"USD","in_stock":false},{"title":".4lb","offer_id":47649874215124,"sku":null,"price":14.0,"currency_code":"USD","in_stock":false},{"title":".5lb","offer_id":47649874247892,"sku":null,"price":18.0,"currency_code":"USD","in_stock":false},{"title":".6lb","offer_id":47649874280660,"sku":null,"price":21.0,"currency_code":"USD","in_stock":false},{"title":".7lb","offer_id":47649874313428,"sku":null,"price":25.0,"currency_code":"USD","in_stock":false},{"title":".8lb","offer_id":47657368715476,"sku":null,"price":28.0,"currency_code":"USD","in_stock":false},{"title":"1lb","offer_id":47561402056916,"sku":null,"price":35.0,"currency_code":"USD","in_stock":false},{"title":"1.2lb","offer_id":47649874346196,"sku":null,"price":42.0,"currency_code":"USD","in_stock":false},{"title":"2lb","offer_id":47561402089684,"sku":null,"price":70.0,"currency_code":"USD","in_stock":false},{"title":"2.1lb","offer_id":47649874378964,"sku":null,"price":74.0,"currency_code":"USD","in_stock":false},{"title":"2.3lb","offer_id":47649874411732,"sku":null,"price":81.0,"currency_code":"USD","in_stock":false},{"title":"3lb","offer_id":47561402122452,"sku":null,"price":105.0,"currency_code":"USD","in_stock":false},{"title":"4lb","offer_id":47561402155220,"sku":null,"price":140.0,"currency_code":"USD","in_stock":false},{"title":"5lb","offer_id":47561402187988,"sku":null,"price":175.0,"currency_code":"USD","in_stock":false},{"title":"6lb","offer_id":47561402220756,"sku":null,"price":210.0,"currency_code":"USD","in_stock":false}],"url":"https:\/\/wholesale.copperconnection.com\/products\/copper-firebrick-decorator-copy","provider":"Keweenaw Gem \u0026 Gift - WS","version":"1.0","type":"link"}
