playing with copper
Having some copper wire on hand,
chunks of copper wire encased in glass
I thought to try incorporating some small chunks into some beads. Now if you are trying to melt copper, it is a cranky metal, and will just throw sparks as you pour on the heat with the torch, until it finally surrenders. It holds heat and conducts it, but doesn’t like to melt.
I expected the bits of copper wire to stick readily to the molten glass, but it was having none of it, only left a dent in the soft mass. Well, I flipped the bead dent side up and placed the chip of copper in the cavity with pliers and then sealed it in with clear glass encasing. Great fun! The bright copper looked fine against the turquoise glass. Turquoise and copper are mined together, a natural pair.
The molten glass behaved differently with the copper heat sink it contained, and I tried to let them cool extra slowly, but they still cracked. A grand experiment, nonetheless. Further trials with thinner gauge wire await. Click on the photo for an enlarged view.
