Since my sphere machine had been broken for months, I decided to grind out a few Michigan Blue Slag pendants to knock the rust off my bones. These are the results! One of them is available in my Esty shop if interested. The green one is from Escanaba, MI in the upper peninsula, the other three are from South Haven, MI in the lower south western part of Michigan.
Here are some pictures of the few spheres I’ve made with slag. Up until about a month ago I was only able to find one piece of slag large enough to make a sphere. Since that time, I’ve found a couple decent pieces. The dark green chunk was the largest. It probly weighed about 7 pounds or so. The dark green is no the prettiest, but I have since found chunks much larger in that color range. The deep blues have been elusive in that size, but the Robin’s egg color one turned out great (at 1.8 inches) as well at the grey/green one (At 1.8 inches).
