In addition to the reaction between copper green and EDP which I talked about last week, copper green reacts with iris orange or raku glass, manufactured by Reichenbach. This glass has a COE of 96 and so can't be used in large quantities with COE 104 glass, but it can be used as frit, small particles of glass used on the surface of COE 104 glass. When it is used in this way with copper green, it produces a bright turquoise line of color adjacent to the raku, as shown in this picture:
The top bead is made with lines of raku stringer over a copper green bead. I make the stringer by tipping the hot tip of a clear glass rod into raku frit, melting and repeating until I have a nice gather of raku. Then I pull it into a medium diameter stringer, which I apply to the copper green core. After melting in the raku stringer, I added a few twists for visual interest. The bottom two beads were made by dipping a core bead of copper green into raku frit, melting the frit in and adding twists. As usual, look for jewelry made from similar beads in my Etsy shop: etsy.com/shop/DeborahDRoss.
