All About Argentium Sterling

Course Description

About this course

Argentium is a sterling silver alloy that has exciting advantages over traditional sterling silver. It does not firescale, is highly tarnish resistant, is more malleable and ductile than traditional sterling, granulates and fuses more easily than traditional sterling, and can be hardened using a toaster oven!

This intensive virtual workshop will teach students to become comfortable working with Argentium® Sterling (AS) sheet and wire! Demonstrations will include proper annealing, soldering, fusing, hardening, and finishing methods. Granulation with both silver and gold will also be demoed, and students can expect to learn how to make their own granules (little round balls), which can then be applied to the surface of metal through fusing or soldering techniques.

Demos will be followed by in-class work time, with the instructor available for real-time assistance. Students will need two devices: laptop, desktop, or tablet for watching demos, and phone or tablet camera so the instructor can see and offer advice during work time.

This course will consist of three sessions. Each session will consist of the following:

  • Demonstrations and work time 10:00AM to 12:30PM
  • Off-camera break or independent work time 12:30PM to 2:00PM
  • Demonstrations and work time 2:00PM to 4:30PM

Cynthia Eid

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  

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.
