Creative Metal Forming

Cynthia Eid has been hammering and forming metal for over 45 years and has co-written the book Creative Metal Forming, with Betty Helen Longhi.

In this in-depth 3-day workshop, students will join Cynthia as they explore synclastic forming, anticlastic forming, and spiculums, while learning to hammer comfortably and with control. Participants can expect to create concave and convex curves that transform a flat piece of metal into elegant fluidity through domed synclasts, saddle-like anticlasts, and tapered tube spiculums. 

Emphasis will be placed on the jewelry scale during this workshop to save time. The first day, students will make a synclastic bracelet and bead.  The second day will focus on an anticlastic bracelet in the morning and anticlastic earrings in the afternoon. On day three, we will make straight spiculum(s) in the morning, and then close one of the anticlastic earrings into an open seam spiculum. After each demonstration, there will be a period for practice, with the instructor available for questions.

A kit of hammers, stakes, and metal will be provided for each student to use during the workshop.  At the end of the workshop, the tools may be purchased or returned.

Whether using hammers and stakes, or hydraulic press tools, Cynthia's sculptural jewelry and hollowware shows her focus on exploring the fluidity with which metal can be moved, formed, and joined.

Cynthia Eid co-authored the book Creative Metal Forming, with Betty Helen Longhi, published in 2013 by Tim McCreight's Brynmorgen Press. In his foreword for the book, Michael Good says the authors "have succeeded in assembling the first comprehensive textbook on synclastic and anticlastic forming." (More about the book available at www.creativemetalforming.com.)  

Cynthia and Betty developed a set of anticlastic stakes, and Eid also works with Knew Concepts and Bonny Doon to help make tools for jewelers and metalsmiths. Lee Marshall has dubbed Cynthia Eid "Godmother of the Knew Concept Saws" since it was her idea for him to produce these saws for jewelers.

Excited about working in sterling silver without the problem of firescale, Cynthia has been working with Argentium Silver since 1999. After meeting Peter Johns (the inventor of Argentium Silver) in 2003, Eid has participated in AS's development. Argentium International, Ltd recognizes her as a Pioneer.

Cynthia Eid's metalwork has won awards for creativity and design, been featured in many publications, and been exhibited internationally. With a BS in Art Education and MFA in Jewelry, Design, and Silversmithing, she has previously worked as a bench jeweler for fine goldsmiths, a model-maker in a gold jewelry factory, and on private commissions. Her work is in museums in the US and UK. Currently an independent metalsmith and educator, she teaches weekly classes at Metalwerx in Massachusetts, and workshops and short courses in the US, Canada, Europe, and Australia.
