Hi Sharon- If you are interested in anticlastic forming I highly
suggest that you get your hands on “Form Emphasis for
Metalsmiths” by Heikki Seppa, considered by many to be the master
of this technique. It is published by The Kent State University
Press and is available from Frei&Borel in
California(510.832.0355) as well as other jewelry suppliers.
Hope this is what you are looking for.
