600-gram Piece Fired

600-gram ''rock''

This is the 600-gram “rock” from my last blog posting, waiting to be carved.

This piece actually did fit in my 6.5″ x 6.5″ x 4.5″ small kiln. I just mixed 1550 grams of copper, which will probably fit in an 8″ x 8″ x 6″.

The scale shows the weight of the powder plus the water. I am not yet ready to make another piece, since there are so many things I learned from this experience and need to experiment some more.

I was asked why I had made such a piece. The answer is that metal clay creations don’t necessarily have to be functional. Sometimes you want to do it for art’s sake. But mainly I was trying to explore the limits of this medium. I wanted to see what it could do and what it couldn’t. Obviously it’s a new sculptural medium – different from the familiar ones, like ceramic sculpting and stone carving – that needs more research and experimentation.

    How long would you fire something that large? How can you tell if the metal is sintered all the way through? Does it matter?

  • Jenny Says:

    Perfect piece, really like this new direction. If I knew I could fire these larger items, it opens up a whole new can of worms.
    How did the firing go? More important, how did you fire such a large piece? Thanks for staying curious.

    Likewise – I have been considering much smaller sculptures and really like this concept that you start with a “rock” just like a real sculptor with stone. I hadn’t even considered carving – stuck in the dark ages, I created my minis squidging and moulding then refining the dried creation. Doh! Must have taken 3 or 4 hours to fire this – or more?

    Amazing! It is a great step in yet another new direction, bravo again Hadar!

  • Hadar Jacobson Says:

    Jeanie, this was Quick-fire copper so I fired it in 2 phases. I gave it 3 hours on the first phase, then cooled, and another 2 hours on the second phase. If there are non-sintered part deep inside the piece, and they don’t compromise the strngth of the [iece, I don’t think it matters.

    Vivien, It took quite a few hours, but I enjoyed every minute of it.

  • Kristan Says:

    Will you be bringing any of these larger pieces with you to the class in Victoria. It would be awesome to be able to see them in person!

  • Hadar Jacobson Says:

    Kristan, I will try. I can’t carry to much weight in my suitcase.
