The Ring in the Epoxy Stone Brass, Ebony, and Inlay of Braided Copper

I use the epoxy lost foam technique to cast a ring with a copper braided insert. The inserts are rings themselves. The main copper ring is connected; 2 other rings that are braided but not connect; I also used the left over brass and ebony epoxy mixture to make a ring that does not have a braided copper core. I mixed powdered brass with epoxy, ebony dust w, epoxy, and JB Weld epoxy.
