ClayMill Metal Clay Extruder is Available at Last

The ClayMill Metal Clay Extruder, an extruder with a 2″ barrel, is now available from PMC Connection. Thank you, PMC Connection, for your enterprise and dedication!

ClayMill Metal Clay Extruder

Let me state at the outset that: 1. this is not a product review; 2. I have no financial interest in promoting this product. I have been providing my input during the development of the ClayMill extruder with the sole interest that it should exist in the market and be available for the metal clay community. That’s because I have seen what can be done with it and believe that its full potential has yet to be explored.

This is something I’ve been waiting for for a long time. A bigger extruder allows us to extrude large mixed metal beads, cuffs, hair pins, and bracelet links, all in one extrusion. Apart from its ability to extrude large items, it also allows us to produce multiple pieces – a few pairs of earrings, for example – when we need to stock up for a sale or a show, again, in only one extrusion.

When I say one extrusion, the total amount of clay is either 80 or 120 grams of powder clay after it has been mixed with water. That means one 100-gram jar of powder or less.

However, there is more to it than the size and quantity: in my book Metal Clay Practice, on pp. 116-127, you can find instructions and projects that show what designs this extruder can produce that are impossible to achieve with smaller ones. One example is the the pattern of the rings on the books cover:

2 rings

Here are some more examples:

Big Bead

This is a 3″ patterned bead.

Ladder Pendant

Band Ring

Hair Band

This is a hair pin made with one extrusion.


Link Earrings


Both the bead above and the pair of earrings were made with one extrusion. The whole bracelet was also made with one extrusion.



Architectural Rings

I’d like to demonstrate here a more basic project that may help get you started. It includes a lot of photos, but only because I wanted to show every detail. The project is actually very simple. The instructions for feeding the barrel of the ClayMill extruder are somewhat different from the instructions I’ve been giving in my books regarding the smaller extruder. The project explains and demonstrates this.

For your convenience the project is available as a PDF file so you can print it out and attach it to the book. Here it is.

    Hi Hadar
    What a good new this extruder, what a nice project
    For the bracelet do you need to make a back up of copper for each piece as for the earings? I would guess no, but I prefer to chek 🙂
    Thank you
    I know now what I would like that Santa brings me for Christmas

  • Jocelyne Roberson Says:

    Those pieces are great ! I wonder how to fire the bracelet with circles in a SC2 🙁 is it possible ???

  • Hadar Jacobson Says:

    Lucie, The bracelet links are patterned all around. No need for a backing.

  • Hadar Jacobson Says:

    Jocelyne, Place it along the edge of the round bowl. It will be about a third of a circle. One link horizontal, the other vertical, and make sure they don’t touch each other.

  • Kelly Says:

    Great! Can’t wait to try it out!! Will this extruder be useful
    In the January class???
    Thanks! 🙂

  • Renee Lindquist Says:

    Can we get one at the January class?

  • Hadar Jacobson Says:

    Renee, I am not selling it.

  • Martina Says:

    Great Hadar! A lot of greetings from Germany!

  • Komala Says:

    Hi Hadar, how LOVELY! I immediately ordered the extruder when it became available on PMC Connection and suspected you’d come up with a really neat project for trying it out! Thanks a bunch, can’t wait to get my hands on it. Komala

  • Christy Miller Says:

    Thanks so much Hadar. I have ordered one and cannot wait to try it out.

  • Loretta Says:

    Hi Hadar,
    Loved your course last spring.
    I have been experiencing a lot of breakage between stove top firing and kiln firing.
    I have tthree questions:
    1) should I avoid any finishing of pieces after stove top firing?
    2 ) If a piece breaks after stove top firing, can it be repaired?
    3) you state that large stainless steel pieces require a metal cage around them – how big is large?
    I have been making delicate but large pieces and sometimes just putting the fiber blanket into the metal cage breaks it at this point….
    Thank you!

  • Hadar Jacobson Says:

    Loretta, After the stove-top firing you are not supposed to touch the pieces at all. Just add carbon and go on to the second phase. Pieces are very brittle at this point and it’s hard to repair them. As for the cages, for big pieces the best steel to work with is Low-shrinkage steel XT. This type does not require a cage.

  • Jenny Ekberg Says:

    WOW!!! I am saving up now for this extruder. I have had so many problems with my Makins extruders, even the one that is supposed to be for metal clay. The rings are almost impossible to screw on and the screw parts break all the time. I will order this soon, Hadar!!!

    Hi, Hadar,

    This extruded is very exciting. I just purchased a larger kiln, so I can do larger piece, like bangles and wonder if the size of the kiln will increase fire and hold times? It-‘s 15 x 6 inches. Getting ready to test it on glass, which is primarily why I bought that size, but sine it will hold a larger ss pan, I thought of larger (or more in 1 pan) mixed metal pieces.

  • Hadar Jacobson Says:

    Judy, It may require longer firing. I suggest that you start with the firing schedules on the instruction manual, do some test pieces, and see if you need to increase time or temperature.

    I have one of makins and picked up one of the Walnut hollow from michaels – really wanted a green one. I found out that all the discs from makins will fit the walnut hollow and vise versa – the tube making disc’s will also fit the walnut hollow unit as well. I ordered the tub discs (small and large) so cant wait to try it out.
