I’m teaching myself Mokume Gane for my traditional processes class
at my college, I’m in the third year of a jewellery and object design
course. I’ve successfully laminated 12 layer copper/brass billets,
which i did in an electric kiln at 880 degrees C (1616 degrees F) for
10 hours. I used bolted mild steel torque plates, in a tool wrap
envelope filled with aquarium charcoal. I flattened them by hand
forging, we don’t have a drop hammer. I’m about to fire my first
billet containing silver, and am in a bit of a quandry about the
temperature to select. Being a poor student, I can’t really afford
for the billet to fail.
It will be 18 layers, copper, 15% shibuichi, and fine silver. Does
anyone have experience with this combination? Would people recommend
sterling over fine silver?
Any suggestions or advice would be much appreciated.
