Rose Bronze Now Available

First, a new workshop has been added to my 2011 travel-teaching schedule. Right after the workshop at Studio 34 (3-day workshop, October 8-10), I will be teaching a 4-day workshop at MetalWerx in Waltham, MA, on October 13-16. Please see the contact info on my updated schedule.

You may recall that a while back I posted a recipe to make your own Rose Bronze. Since then, I have re-formulated Rose Bronze into a new product, now available on my online store. The firing instructions are already included in the Instruction Manual. It does not require a separate firing schedule and can be fired with copper, bronze and Pearl Grey Steel in the same firing batch.

Here are some pieces made with just Rose Bronze:

The following are rings with Rose Bronze, created by Jan Carpenter:

And here is a piece of Rose Bronze combined with Pearl Grey Steel:

When combined with clays other than Pearl Grey Steel in the same piece the pink color may disappear and create other colors, as demonstrated in the project “Mixing Colors – Rose Bronze Rock” in my recently published book: Patterns of Color in Metal Clay.

For the full color range, and to see the difference between Rose Bronze and copper, here are photos of all five colors (click to enlarge):

    That looks like a lovely colour. I don’t work with metal clay myself, but I really enjoy seeing your work and the many different colours of clay you have. Colours that look very nice both on their own and mixed together.

  • Jenny E Says:

    Fantastic. The colour is really rose.
    I can’t wait to order some of this.

  • Lynn Latta Says:

    What is your opinion. I have been using pickle to clean the bronze and it takes off all the black and then I sand a little and then tumble. It is saving me lots of sanding time. Have you ever tried pickle?
    I know it can’t be used for steel.
    Hope you are well.

  • Hadar Jaobson Says:


    I never pickle metal clay. It’s porous and you need to neutralize it after pickling. But it’s really not necessary. The radial discs will easily take off the black. If you want to cut on sanding time, burnish your pieces before you fire them.

  • Janet Simmons Says:

    Hello Hadar – Love the new color – how to you burnish before firing?

  • Terri Sidell Says:

    Rose Bronze how exciting!! Those of us at the Metal Clay Conference showed off our pieces that we made in your Mokume-Gane class to the Japanese presentors on “New Mokume-Gane”. They thought they were the only ones that have come up with Mokume in Metal Clay, and they are being very secretive about it. Terri

  • Hadar Jacobson Says:

    Janet, with a burnisher or any stainless steel object like a spoon. Just like you would burnish a finished piece of jewelry. Rub the surface hard.

  • Steve Brixey Says:

    Hader, I am a long time reader of your blog and bought three books. I have used BronzClay successfully, but liked the idea of powder and making only what was needed. I have been trying to do the samples as you describe in the instructions, but my finished pieces are all crumbling. I have tried higher temperatures and am up to 1490, with the same result. I have a top loading Skutt kiln for glass work and fired in a stainless container filled with charcoal. Not sure what I am doing wrong.

  • Kathryn Knoll Says:

    Can we mix glycerin directly with the dry clay to get flexible clay or do we have to mix with water first and then add glycerin and roll/mix. I see that you have a demonstration with silver, I think. Can I do some thing like that with the dry mixes of metal clays?

  • Sutton Norris Says:


    In your photos that show a sample from 5 clays, what are the “silver” looking samples made from – White Bronze or Pearl Grey Steel? I recognize the others – bronze, copper and steel.

  • Hadar Jacobson Says:


    In the circles’ photo the one on the top right is white bronze and the one on the bottom right is PG steel. In the ring’ photo white bronze is on the left and PG steel is on the right. In the rocks’ photo it’s the same. In the last photo white bronze is on the left and PG steel is in the middle. There is no carbon steel in these photos.

  • Hadar Jacobson Says:

    Kathryn, I usually mix it with water first and then add glycerin. I must say, though, that my traditional copper and bronze work better than the Quick-fire as flexible clay.

  • Jenny Ekberg Says:

    Hi Hadar, I just wanted to say that I find that the same thing is true for commercially available clays! For bronze clays, the “old fashioned” ones that take long to fire mix better with glycerol than the new fast-fire versions.
    I have a question too. I accidently added some dried flexible clay (containing glycerol, but DRY) to my slip jar. For the first time, a piece broke in the kiln that had some of that slip in it. Do you think it had to do with the glycerol?

    (I can’t wait to get your clay! My last order seems to have really disappeared in the mail – Australia post has no record of the parcel arriving in Australia. So hopefully my new order will come).

  • Otteline Says:

    Hi Hadar,

    I burnished before firing and some spots stay powdery. What does that mean?

  • Hadar Jacobson Says:


    It most probably means that the piece is not completely sintered.

  • Sherry Johannes Says:

    The Rose Bronze and new Pearl Grey Steel XT combo is beautiful!
    When making canes with the new Pearl Grey Steel XT should one less PG Steel than Rose Bronze like we have been doing? e.g. 6 cards rose bronze; 2 cards pearl grey steel XT…or? It appears to be half/half in the photo but not sure. Thank you in advance.

  • Hadar Jacobson Says:

    Sherry, That’s the correct ratio. It appears to be more steel because it tend to take over. But since we are actually under-firing when combining it with low-firing clays, we need to use it in small amounts to allow it to sinter.

  • Jahan Says:

    Hi Hadar,

    Can Rose Bronze (or other bronze clays) be combined in one piece with Pearl Grey Steel XT, and fired and have the piece come out OK?

    Sorry if you have already addressed this question, I’m a bit new to this.

  • Hadar Jacobson Says:

    Jahan, Absolutely. It’s one of the best combination. Fire at the lower temperature of rise bronze. Good luck!

  • Michelle Glaeser Says:

    Does the Rose Bronze patina brown in Baldwins like the copper? I’ve got some out of the kiln, just haven’t tried it!


  • Hadar Jacobson Says:

    Michelle, It does, but not to the same extent as copper. I actually try to maintain the light color. You can do it by soaking the pieces in oil foe about an hour.

  • Michelle Glaeser Says:

    Thanks for the tip on the oil! I was going to try to mix it in a bronze/copper piece, like the mixed metal rock. I don’t think it will work as planned. I assume the oil would make the copper not change as well? I was thrilled with the color of the premixed Rose Bronze. It’s lovely!


  • Hadar Jaobson Says:

    Michelle, You can patina the rock and then soak it on oil. Apply the patina only where you want it. Rose Bronze makes good contrast with steel, but not with the other metals.
