Fold Formed Copper Enamel Earrings in Shades of  Blue.   Fold forming as the process of heating  the copper, folding it in a vice and then hammering the fold, reheating the copper and unfolding and hammering the seam creating hills and valleys in the metal. Layers of blue enameling glass was then sifted onto the surface and torch fired until glossy.   Rose gold filled ear wires.  One of a kind!
