What a Bigger Extruder Can Do

On page 68 of my book Patterns of Color in Metal Clay you can see a photo of discs that I made for a polymer clay extruder, 1″ in diameter. This extruder is far from meeting our needs, but that’s all I have for now. I think I must have bought every type of cookie press available – both manual and electric – and they don’t seem to work. I also tried to construct my own from plumbing pipes, but it is not as easy as the 3/4″ diameter one. So I’ve been working with the polymer clay extruder, and I’d like to share my results with you. The extruder is big and heavy, but I will bring it to Studio 34 and Metalwerx next week so we can experiment together.

This is not the bracelet from the project on p. 78. Jennifer has that one, and I hope she is still happy with it. This is a new one. All the links were extruded at once through the slot of a 1″ disc.

These are designs that are impossible to make without a bigger extruder and a matching tube adapter. Here is a photo next to a penny, for scale.

How easy it would be to extrude decent size beads and bead cores.

And for those of us who like big, chunky rings:

Speaking of which: it has come to my attention that people think it is possible to smear silver paste on the inside of a ring to avoid allergic reaction with the skin. I strongly recommend against it. If you are familiar with my book Silver and Bronze Clay: Movement and Mechanisms, you probably know how disastrous the reaction between silver and bronze can be. You may end up losing a lot of expensive silver.

This was a copper/bronze mokume-gane ring with silver lining before it was fired. Another ring lost its shank altogether.

Lining rings with silver has to be done in special ways, and I will teach all about it in my Mokume-Gane Rings classes.

    Hadar, I will be joining you at Studio 34. I can’t wait to see what you have planned for the class!

  • Kim Swanson Says:

    Hi! Hadar,

    Any info. that you can share on “Rings”, as far as handling alergic reactions. I am anxious to make a few rings and need guidence on lining?

    Thanks, Kim

  • Noël Yovovich Says:

    Merely lining a ring will not help you in any case. The fingers on both sides will still be in contact with the base metals. On top of that, with silver added, you create an electric potential between the more base and less base metal that will etch away the base metals– speed determined by your environment and skin chemistry.

  • Hadar Jacobson Says:

    I haven’t said that merely lining will help. I was responding to what I heard people think they should be doing and was trying to save them some money and disappointment.

  • Seb Says:

    Any thought on writing a book on ring making for all of us who cannot attend your classes?

  • Hadar Jaobson Says:

    Seb, Many thoughts, trust me. These things take time, though.

    Hadar, did you check this on a polymer clay website? large extruder for ceramic clay by IKEG I didn’t use/find it, just on web tonight.
