Tuscon Gem Show Rock Haul

I've been avoiding it for years but I finally did it...I made it to the Tuscon gem shows. I've actually dreamed about going for a very long time but, yes, avoided it...you know why. I have very little will power...

150 year Lake Michigan beach-tumbled slag glass specimens. Created during the iron smelting / purification process of the mid 19th century. The main impurity in the raw iron was silica (glass). The iron was melted using the intense heat of a hardwood fired blast furnace. The slag floated to the top and was skimmed off and discarded in the big lake. It has tumbled in the waves for over a century.

Leland Bluestone: mix of blue glass and other chemicals can also appear purple, gray, green. "From 1870 to 1885, Leland was a smog-filled industrial town... anchored by the Leland Lake Superior Iron Company. After the smelting industry failed,... heaps of slag, were dumped into the harbor. Slag is a byproduct of the smelting process: raw ore is heated, and the desired iron ore is separated from various natural impurities. When those impurities cool, the result is stone-like slag.MyNorth.com

From 1870 to 1885, the Leland Lake Superior Smelting Company operated in Michigan. During this time, slag from the smelting operation was dumped into the lake. This slag is a blue, glass-like stone known as Leland Blue which now occasionally washes up onto Michigan beaches. Pieces range in color from bright, cobalt blue to grey-greens. This particular piece is what I would call slate blue. I love the idea of this being upcycled, reused industrial by-product. It makes for a lovely piece of…

Back in the late 1800’s, the Leland Lake Superior Iron Company was taking iron ore from the Upper Peninsula, heating it up until it was molten and the result was pure iron. The leftover impurities were cast into…

A single cabochon of Leland Blue slag glass from the shores of Lake Michigan serves as the focal of this primitive piece---if you arent familiar with the cool history behind this old material, read below! I have bezel set it in deeply oxidized copper and then soldered it to a weathered copper tube that I have beaten to hell and back. A tripled length of faux suede cord (no animals harmed!) threads through the tube and connects at the back of the neck using one of my own hand forged copper…
