I really love the color and texture of this piece as it seems to fly away on the raven’s wings. The irregularities of the slag glass (Read the nerdy, yet necessary, natural history below.) add to the movement and motif of the raven, a symbol of wisdom in many cultures.
LELAND BLUE (ANTIQUE FOUNDRY GLASS) c. 1875-1900
This unique “gem” is a byproduct of the short-lived days of smelting iron ore in Northwest Lower Michigan. The ore from the Upper Peninsula’s Mesabi iron range arrived in Leelanau Co. by schooner. A charcoal made from beech and maple hardwoods plus a local limestone flux were used to refine the ore; the slag byproduct was considered waste and dumped into Lake Michigan. This material ranges in color from black to green, to blue and purple, with the various shades of water-like blues being the most prized and rare. Under 2% of the slag created was blue, depending on environmental factors. The lucky and determined beachcomber may still find pebbles along the shore.
