Introducing Hadar’s Clay™ – White Bronze


The pieces in the photos above (click to enlarge) are not made out of silver or steel. They are made out of a new copper alloy that I call “White Bronze.” This new form of Hadar’s Clay will soon be available for sale on my Web store.

Here is how the pieces looked before firing:


I have prepared samples of Quick-fire Copper, Quick-fire Bronze, and White Bronze, textured and non-textured.


The following photo is taken next to a silver piece that may be familiar to you as a project from my first book.


Here are some process photos:


Textured and folded






Next, some pieces in copper and bronze. Unlike the copper and bronze pieces, the White Bronze piece was textured before folding. When White Bronze is not textured, it comes out as smooth as copper and bronze.

White Bronze is compatible with both copper and bronze; there is no undesirable reaction between them as there is between silver and bronze.

The firing temperature of White Bronze clay is a lot lower than that of bronze clay, though. So in order to make combination pieces of either copper and White Bronze or bronze and white bronze, the copper and bronze parts have to be fired first.


White Bronze was wrapped around fired copper, then fired.


The result is the piece on the left. On the right you can see the same piece with silver substituted for the White Bronze.

There are still some tests that need to be done. For example, I need to determine the extent to which White Bronze clay sticks to copper and bronze. I will post my results soon.

As you can see from the photos, the shrinkage rate is similar to that of Quick-fire Copper and Bronze. The firing time is about the same and the temperature is lower. The fired pieces are as strong as those of copper and bronze.

Important Note: This is not “nickel silver” (also known as “white copper,” “German silver,” or “alpaca”). This alloy contains no nickel.

White Bronze clay will be available on my store as soon as I complete my testing and write an instruction manual. I hope you like this low-cost addition to the palette of metal clays.

    HI Hadar

    I can’t wait to try it, looks greate and I like that it sounds a bit cheaper than silver clay.

  • Anna Siivonen Says:

    Looks great! What metals does it contain beside copper? Do you know anything about patinas on it?

  • Michelle Roth Says:

    Amazing! As usual.


  • Lori Phillips Says:

    Hadar, This new clay is wonderful! Does this clay have to be fired the same way as your original bronze and copper clays?

  • CindyC Says:

    It looks very exciting Hadar!

  • Finola Prescott Says:

    This looks really interesting – I am yet to try any of these clays as I don’t really have the setup, but the white bronze looks like one I will be looking forward to using.

    And all your designs are wonderful too-from the intricacy of the trees to the simplicity of the folds and wraps, lovely.

  • Hadar Jacobson Says:


    It’s a lot cheaper than silver clay.

  • Donna Lewis Says:

    Hi Hadar, lovely! Hoping your alloy choice will not cause any issues. For those of us who are color challenged I imagine this looks sexy as all get out with the steel (provided of course the steel is fired first)
    I’m assuming this white bronze will be the same challenge with silver as the other bronzes are.
    Thank you for putting in so much time for our art. You are the best!

  • Debby Thompson Says:

    Fantastic! I’m still on your original copper and bronze. How does it work with those? Will the price be similar? I can’t wait to try it.

  • Diane Sepanski Says:

    Hadar….you little minx! What will you come up with next?! Love your creative genius! Keep on keeping on (if only I could keep up).

  • Judy Pagnusat Says:

    You have done it again. Most of us can’t keep up with your exciting advances! I want to try it all and still am using your original copper & bronze clays. Thank you for being so adventurous and thank you for being so generous with your findings.

  • Dinah Bourdon Says:

    Now this looks awesome! I like the low firing temps and low price ( I hope)

  • Hadar Jacobson Says:


    It works well with copper and bronze. I’ll show some photos in my next posting. And the price is similar.


    It seems to take patinas very nicely. Again, I’ll show a photo on my next posting.

  • lindamay Says:

    Hadar you ARE a mover and a shaker. Look out Rio and etc.
    I am wondering what the ratio is… for purposes of accepting/bonding with enamel?
    One more experiment for me to try.

  • Lynda Says:

    Very very exciting!!! I can’t wait to see more…….

  • Jenny James Says:

    WHEN WHEN WHEN HADAR?!!!!!!????? When can we have it!!!!!!!!!!??????????!!!!!!!!!!?????????

  • Nancy Garber Says:

    Very exciting. I am anxious to combine all of the clays. I feel very confident to try combining now that I have had your workshop. I will add the new clay to my teaching.

  • Michele Milana Says:

    Hadar, do you ever sleep??? I’m looking forward to trying this new metal, thank you for all that you do.

  • Lisa Kirkeby Says:

    Hadar, What is it made of?

  • Katherine Stott Says:

    You’re an animal, Hadar!! And I say that in the good sense, and with love! I’m continally amazed by you, as is everyone else. I’d like you to bottle whatever it is that keeps you going, going, going, and sell us some of that! You are simply at the top of my most admired list.

  • Marty Farrell Says:

    This is exciting! If it is anything like your copper and bronze I will love it. Having a ball using your clay. The fiber box and carbon works like a charm. Thank you for your info as usual!

  • maria delgado-pontani Says:

    Hadar, you’ve done it again…Can’t wait to try the white bronze!!!

  • Patricia O'Neill Says:

    Oh, I am so excited by the news!! cheap, easy and compatible with the other clays… what else to ask? I can’t wait to try it. Hadar, thank you so much for your creativity!

  • jenny james Says:

    … is she out of town or is she avoiding us?

  • Hadar Jacobson Says:

    What do you mean. Jenny? Your question about when? I though I answered that, sorry. In about 2-3 weeks. In the meantime, watch for the next posting.

  • Bobbie Says:

    Oh Happy Day! Thank you so much Hadar, this is the best news.

  • Jenny James Says:

    Got a little over-zealous, like a puppy waiting for Scooby Snacks. Two to three weeks …awesome. I think the most exciting thing is that we can have a light colored metal that looks and behaves like silver but isn’t expensive like silver. I am looking forward to being able to make much bigger objects without stressing out about the cost.

  • Christine Dammn Says:

    Hadar, this is the most exciting material yet! I can’t wait until my kiln arrives! I feel like I did when I first started working with polymer– couldn’t find what I wanted so made my own. Now I can have the metal findings and pieces that I can’t find/fabricate. Thanks!

  • Linda Fountain Says:

    After looking at your fantastic work I can’t wait for my shipment to arrive in oz. I have more ideas in my head than I know what to do with. Is there any visit to Australia planned for the future? I’d love to attend a workshop. Can any of your clays by fired with porcelain?

  • Hadar Jacobson Says:

    Hi Linda,

    I taught a workshop in Sidney and Melbourne in October. I would love to come back, but it’s really up to the organizers. About the porcelain, I don’t see why not. The sintering temperature is much lower than the porcelain’s. Good luck!

  • Jennifer Saks Says:

    Hadar, I bought some of your white bronze, and I can’t wait to try it out!! It looks just gorgeous! I do have a question: Have you any ideas re: what to use for a bezel with this medium? (or with the regular bronze too, for that matter). I have several stones I’d like to set, and wish there was some sort of bezel wire I could get to use with white bronze. I don’t suppose nickle silver could be bonded to it in any way, could it? I just don’t relish the idea of trying to make my own bezel wire. Any ideas?

  • Hadar Jacobson Says:

    Jennifer, you can set any kind of bezel cup in all the clays. If they are pressed deep enough they will be held in place by the shrinkage of the clay.

  • Jennifer Saks Says:

    But what about making a bezel for an irregularly-shaped stone? That’s actually what I was referring to but neglected to explain. Could I make a bezel out of silver bezel wire and press it into bronze clay? If so, that would be great…sounds like it would be a close match!

  • Hadar Says:

    Jennifer, Silver may react with the metal. I would get a 26 gauge copper, brass, or rich low brass (looks like bronze), and cut it with regular scissors to make a bezel wire.

  • Jennifer Saks Says:

    Thanks, Hadar. I was a little afraid of that being the case. I will do that. 🙂 The thing I was trying to avoid was making sheet strips out of white bronze…not sure how successful I’d be with that. But for the other bronze and copper the sheet will work fine, I’m sure.
