What is anticlastic forming? In this class, learn foundational techniques about how metal moves and creating volume from a flat sheet with a hammer and stake! From small intricate jewelry to larger sculptures and vessels, these techniques can be scaled once learned to suit your work. We will be covering not only creating open forms, but hollow forms as well.

Anticlastic forming, also known as shell forming, encompasses the basic structures that metalsmiths of antiquity used to make hollowware like goblets and teapots. Pod forms, lily forms, shallow bowls, and hollow bangles are all examples of shell forming techniques.

Open the world of beautiful organic flowing forms with this class!

Techniques covered include:

  • What is anticlastic shell forming?
  • Understanding the types of shell forms and their variations
