Kiln Mokume Gane

Beginning Mokume Gane using your Digital Controlled Kiln


Participants will learn a western influenced method to make Mokume Gane by using a digitally controlled electric kiln to fire a copper and silver billet. Participants will start by making their own billet, pattern it into sheet metal, and fabricate a seamless mokume gane ring. There are several technical demonstrations, so beginning metals & jewelry skills are needed to be successful in this workshop. 

Day 1 of the workshop covers cleaning metal and firing the billet. With this method, correct temperature and amount of firing time are critical, so using an eclectic kiln with a digital controller is required. 

Day 2 focuses on making patterned sheet metal, but first the billet is cleaned up and forged. Its handy to have a belt sander or angle grinder to remove uneven edges and after forging the billet by half, a rolling mill is used to get a uniform thickness.

Day 3 finishes with a ring project.  A washer is cut from the mokume gane sheet and turned into a seamless band ring using a nylon hammer and ring mandrel. The ring will be finished with a sterling silver liner with flared edges.
