I just attended a two day workshop with James Viste where he revealed the secrets to successfully executing mokume in a home studio without the need for expensive special equipment. Using copper and brass, standard torches, small handmade brick kilns, and hammers. In the picture you see a copper and brass billet. This billet would then be forged to 1/3 its height and then patterned. More forging is done while you pattern the billet.
