Today was the 5th time I’ve fired copper and bronze clay. All rocks beads in this batch, and all seemed to have fired well. The clay is Hadar Jacobson’s bronze and copper clay powder, and I fired using the directions from her blog. The combination of two metals in the same load did not have any effect on each other. Its easy to tell the bronze and copper clay from each other in the pre-fired beads.
After firing, they almost look the same. But the bronze clay shows some of the patina from firing. This will polish away when I buff the beads. I will try to recreate it by applying heat with the torch, after the bronze is polished.
It was a good rainy day, so it was easy to stay put in the studio to finish a second batch of copper and bronze to fire in the kiln tomorrow.
