I am gunna send some individuals your way to read this. Fantastic, totally amazing.

    I don’t have a website, just an email. I am so excited about the clay and learning about how to incorporate into my jewelry making. It all seems soreal. (sp?) I expect great things.

    Yours trully,

    I took my first clay work shop from Vicki McGowen.

    Hadar, your blog is so darned helpful and interesting. I’ve passed on the Beautiful Blogger award to you, details on my blog.

  • Jim Perkins Says:

    Is it possible to solder components to bronze or copper that I solder to silver?


  • Hadar Jacobson Says:

    Hi Jim,

    Yes, there shouldn’t be a problem if the copper or bronze are fully sintered.

  • Jamie Says:

    I am trying your new powered clay and have a question I am sure someone can answer. I am making a pendant out of the pearl grey steel and want to attach a rose copper flower to it…which paste should I use to attach the two pieces…the rose copper paste or the pearl grey steel paste. Your response is greatly appreciated.


  • Hadar Jacobson Says:

    Jamie, You mean rose bronze or copper? If you use copper you can use a paste that is a mix of the two and fire at the high temperature (schedule B). If it’s rose bronze I would fire the steel first at the high temperature, then add the flower and fire again at the lower temperature.

  • Jamie Says:

    Thank you so much. I did mean rose bronze and not rose copper. So if I add the rose bronze after I have fired the steel would I simply use the rose paste to connect the two pieces? Should I burnish the steel before I add the rose piece?

    Once again I really appreciate your response. I am in Virginia and I don’t know where to find classes of your caliber here.


  • Hadar Jacobson Says:

    Jamie, No need to burnish, just clean. I would use, though, some mechanical connection to hold the rose bronze in place. By the way, I will be teaching a workshop in October at Studio34 in Rochester, NY, and Metalwerx in Waltham, MA.

  • Diane Says:

    Today I tried your copper Quick fire clay and love it. It mixed up so easily, handled beautifully and released well. I cannot wait to fire my work. I am so glad I found this product and cannot wait to try the Quick Fire Bronze and White Bronze I ordered. Thank you!

  • Jamie Says:

    I just tried the white bronze clay and I am very discouraged. I tried to make a notebook pendant. I created it and it dried for two days before I could fire it. I have a larger kiln and when I fire bronze I have to lower the second stage firing by 10 degrees than the instructions state so I lowered the second stage firing for the white bronze. I fired the first stage at 1000 for 30 minutes…it was not a thick piece and the second stage at 1230 for 2 hours. Well, I can not even find my pieces in the charcoal, I believe it simply burnt up…very said and I do not understand.

    Anyone else have a problem with white bronze?


  • Hadar Jacobson Says:


    White Bronze has a very narrow range of sintering temperature. It can go very quickly from not sintering at all to melting, as stated in the instruction manual. And I always recommend to make test pieces before firing an actual piece of jewelry so you can find the sintering temperature in your specific kiln. With every kiln the temperature is going to be different. Good luck!

  • Lucille Parenteau Says:

    Hi Mrs Jacobson

    I did not find your e-mail address to submit a question, about firing gems in carbon.

    I made a bronze bracelet from your book Silver and Bronze Clay – Movements and mechanisms. It came out gorgeous except for the cubic zirconias gems which lost their brilliance. I used thoses gems in fine silver without any problem. I wondered if this was due to carbon firing (coconut shell). Is there any solution to protect the stones while firing in carbon?

  • Hadar Jacobson Says:

    Lucille, This happened to me several times (although not always) and to other people as well. Most people say that tumbling restores the brilliance of the stones. I haven’t tried it myself though. My email is hadar@pacbell.net.

  • Deanne Says:

    Hello Hadar,
    I have recently experiemnted with White Bronze. I am quite pleased with the results but was surprised about the amount of coconut carbon that I lost to ash. I was wondering if that was because it is recommended to fire without a lid? If so, is it necessary to fire without the lid? I have been working with Bronze for a couple of years and use a lid during firing and have consistently good results. Thanks in advance for your help!

  • Hadar Jacobson Says:

    There are different kinds of coconut carbon. The one I use does not produce a lot of ash and I fire without a lid. I’d say, that if you do the first phase on a stove top (without a lid), you can use a lid on the second phase. Good luck!

  • Bernadette Denoux Says:

    Hi Hadar,
    I throughly enjoyed your class. I’d been facinated by everything you have researched, and really needed the class for it to make sense in a real way. I can’t wait fot the kiln to arrive so I can fire the pieces that I have, and have rearranged my whole studio to make room for it. I guess I get inspired after each conference which is good for me. So, after I fire those things I bet I’ll have lots of questions. Thanks for being so available and having this blog. I hope you and your charming husband had a good trip home.

  • Steve Brixey Says:

    Hi Hadar.
    I just received some Bronze Clay (Traditional-Flex) and have some older Bronze Clay (not Quick Fire) and wondered if I can combine them? I just have a little of the older powder. Not enough to make anything by itself and too much to toss out…
    Thanks, Steve

  • Arlene Sherman Says:

    Just started to work with your powder clay, so far just the Rose Bronze. Your directions are great so even a novice like me can achieve great things.
    Question for you, can you use lavender oil and slip on your metals like you can for PMC3?

  • Hadar Jacobson Says:

    Arlene, Lavender oil and slip are fine. Personally I find it better to use thick paste instead of slip.

  • Ro Says:

    Well, we are about to fire our first pieces in Hadar’s clays. We are sooooo excited to see the results. They are a dream to work with.

  • Kim Says:

    Hi Hadar,
    I have found all of your information so helpful. I love working with your clays. I am wondering if you have ever tumbled the fired pieces and if that will also work to polish pieces? I am working with Low Shrinkage Steel XT, Bronze XT and Copper…all separately so far. Thanks for your help and this great blog!

  • Hadar Jacobson Says:

    Kim. If you tumble steel it will rust. The rest of the clays can be tumbled. But there are other ways to polish. Have a look at the file on my blog: “Finishing Fired Metal Clay”.

  • Kim Says:

    Thank you, Hadar. I am so grateful for your quick response and all of your resources.
