Introducing White Bronze – Continued

Here is a report on my further testing of White Bronze clay.

1. I’ve been asked how White Bronze reacts to patina. You can see the result in the photo below.

2. How well does it pick up textures? I tried to make my Collage of Textures pendant (first project in the my first book) with White Bronze. It reacts well with liver of sulfur and seems to pick up textures very well.

3. Smooth/matte/satin finish. Achieving these finishes was no harder than with silver, copper or bronze clay.

4. Combining copper with White Bronze.

5. Reaction with bronze. I fired both bronze and White Bronze on a copper piece, without sealing the bronze as I would have done with silver. Both sintered, and there was no alloying or change in color.

The following bead has been waiting for this moment for about two years. I fired the copper and the bronze with the intention of adding silver to the bottom part. It was just then that I found out about the reaction of silver and bronze (you can read all about it in my second book), so I stopped working on the bead.

6. Sticking to copper and bronze. Since the firing temperature of copper and bronze is higher than that of White Bronze, copper and bronze need to be fired first. I placed an unfired piece of White Bronze on a fired piece of copper and a fired piece of bronze, and re-fired.

t-Sticking

The results were inconsistent. I repeated it a few times and sometimes they stuck, sometimes they didn’t, regardless of whether it was copper or bronze. My guess is that they will stick if there is a way of creating some pressure between them. The following test supports this hunch. It seems that the pressure of the carbon on the piece was not enough.

7. Inlay.

The following photo shows side by side inlay of White Bronze in copper (R) and inlay of copper in bronze (L).

Color comparison

As you can see, the contrast between bronze and White Bronze doesn’t seem very sharp. Over time it may improve when the bronze yellows some more. White Bronze has not changed in color so far.

The inlay pieces above were only partially successful. In the center of the pieces the metals bonded well with each other. On the peripheries some of the inlay chipped off and required repair and re-firing. It seems that on the peripheries the pressure is lower than in the center.

In the following piece I avoided inlaying the White Bronze on the borders of the piece. The bonding was fine.

    I second Diane’s sentiments 🙂

    When can we buy it? Is it a matter of days or weeks or months?! …. Are we there yet? Are we there yet? Are we there yet?

  • Karen Richard Says:

    When will we be able to purchase???? Cannot wait!

  • Donna Lewis Says:

    Hadar, you are amazing!!!!!!!!! Thank you thank you so much. These are gorgeous, your white bronze will change everything with the base metal clays. Genius, incredible patience and perseverance and just plain guts!

  • Marty Farrell Says:

    Great examples! When can we buy some?

  • Hadar Jacobson Says:

    Jenny, Marty,

    Not months, weeks, 2 to 3, hopefully sooner.

  • Lynda Says:

    Awesome Hadar! What patinas did you use on the first piece?

  • Hadar Jacobson Says:

    Lynda,

    I used both “patina blue” from Sophisticated Finishes series and dye-oxide patinas.

  • Kimberly Shaffer Says:

    You are an amazing woman Hadar and so giving. Thank you so much for all you do and share with us with the metal clay. I am just about to embark on trying bronze and copper so I have so much to learn. I am very excited to hopefully have the three metal colors if possible. With your help, determination and testing, it looks like that might be possible now. I actually like the sutle (softness) of the white bronze pieces you have done. Are you using the blanket box or the stainless steel box now? I couldn’t tell by the blog if you were only using the fiber box now or not. Thank you so much!

  • Katie Hanrahan Says:

    Okay, you must never sleep! Or you’ve been cloned and there are two or three of you working 20 hours a day!! Incredible, Hadar! Thank you so much for your wonderful and generous contributions to the ever-exciting field of metal clay!!

  • Sarah Triton Says:

    Hadar, I know I have said it before, but I think you are the quintessential Wonder Woman. How you find time for all this product development, your teaching schedule (home & abroad)and consistent & informative blogging never ceases to amaze and bless us all! I may have to re-think going to Purdue and come out there to study with you instead. Seriously!

  • Carol Faith Says:

    Hadar, Thank you for your devotion to metal clay we all benefit from your tireless experimentations.
    I know that their are many silversmiths all over the world waiting to place our orders for white bronze.

  • lynn edmonds Says:

    well done Hadar you are truely inspirational – i look forward to playing …..

  • Hadar Jacobson Says:

    Kimberly,

    I don’t use steel boxes anymore. I fire all clays in a fiber blanket box. White Bronze just has a different firing schedule.

  • Ruth Baillie Says:

    Wow Hadar! This looks great. Look forward to seeing and hearing more.
