Wonderful video Karen and CoolTools. I'm making a project that will benefit from the techniques used here, and am grateful to know how to resolve the different shrinkage rates with the two different clays, as well as the firing times/temps. The bracelet shown at the end? To die for, gorgeous! Thanks again for the information.
Great project, Karen! So many helpful tips that can be applied to different projects. Is there a reason you didn’t lightly rehydrate the copper “overlay” after attaching it to the bronze base (and letting the moisture soak in a bit) before cutting out the shape? I would have thought it might help avoid some of the separation of the delicate copper design and minimize any rough edges during cutting. Thanks so much for everything you do to educate us!
Thanks Margaret! When playing around with this technique, I tried spraying the piece before cutting, also thinking it would help with attaching the components before cutting, but the result was the softened copper ended up smudging along the cut edge. As I pulled my needle along, copper that I had passed through ended up carrying with my needle and smeared along the edge, resulting in me having to do a good bit of sanding anyways and then the pattern along the edge ended up being not as crisp and looked blurred. Thanks again for your kind words! Karen
I really like this idea, but you can hardly see the copper on the bronze. I wonder if the firing temps of the copper or bronze could be used with any of the silver clays? Now that contrast would be amazing. I love the hue of that bronze. Thanks for the vid.,
I can’t wait to make this- it’s beautiful! I’ve all the materials here and bought myself a kiln (with accessories and carbon) in the Black Friday sales. Quick question- is it okay to tumble pieces that have stones in them? (I’m using a preciosa nano gem). Thank you! 😊
How exciting! Yes, you can tumble a piece that has a gemstone. As long as the gemstone is securely in place, you'll have no issues. We tumble all of our pieces with stones. Thanks for watching!
What did you do with the left over bronze clay that had the copper texture on it. You put it aside and then didn't mention it again. Would you have done your best to remove all the copper texture and then used as normal bronze?
Thanks for asking this, I should have thought to mention what can be done with that left over clay. While you could try to pick the copper off, I just am keeping the left over in a clay hydrator labeled Cyprus + Aureus, that way i know to use it with the adapted firing schedule. I've taken some and folded and rolled it (like is done when polymer clay is being conditioned) and the patterns have blurred to be a kind of marbled look- which i'm looking forward to seeing how that fires! I've also just folded and rolled the clay until the two types are throughly mixed and I am left with what fires to be a slightly more rose tinted or warm colored bronze. The clays retain moisture so well that I have not had any issues with them drying out while being rolled and mixed. Thanks again for asking! Karen
I was thinking that the scrap combo clays could be used on the reverse to make a decoration on either the bail or a "window" for the stone on the backside of the pendant.
Question for you I had a problem with my Syprus copper bracelet while I was fire nets in the carbon it broke and pieces can you tell me the problem please thank you
Hi Marlin, it sounds like your pieces aren't sintering. I recommend reaching out to our customer service at sales@cooltools.us and we can help you more by discussing this to troubleshoot.
Thanks so much! We have not yet tested this firing schedule with a ceramic vessel. As ceramic firing vessels can retain heat and increase the temperature, you may need to fire a test piece and lower the temperature by 25 degrees if your test piece has blisters or an over heated surface. If you would like, I'll test it out and let you know! Karen
@@cooltoolsvideos (Oops! I hit the 👎 by mistake! I fixed it, though.) Thank you so much for the information! Sure, if you are able to test it, that would be great! 👍👍🙂
Hi Karin, I have not experienced this and can only guess as to what may be going wrong. Do you mean the bronze detail is falling off or the piece itself is breaking? If the piece itself is falling apart at joints, did you throughly dampen the elements of your piece prior to joining them? If your detail is falling off, did you spray the piece as a whole, very generously after cutting out your shape? I’m wondering if it could be the result of how the pieces are being handled between the two phases? With all the binders gone the piece is very very fragile- perhaps try doing a firing where the first phase is done on top of an inch of carbon in your firing container, and then instead of handling it and giving the piece opportunity to break, just gently pouring more carbon on top of your work to bury it for the second phase. Karen
@@cooltoolsvideos thank you for responding yes I was trying to do it with the carbon next I already went down with the temperature the pieces without the stone are ok just the once with the stones fell apart . So yes I guess putting it in carbon might be the answer thank you so much

Good stuff! Thanks!
Can I use a torch instead of an oven? This is how I usually do with silver clay.
Hello, Cyprus and Aureus Clays both require being submerged in carbon while firing in order to sinter, so they need to be fired in a kiln.
I can’t wait to make this- it’s beautiful! I’ve all the materials here and bought myself a kiln (with accessories and carbon) in the Black Friday sales.

Beautiful!! (As usual!) Question: If I'm using a ceramic firing vessel (in a kiln), can I still use the same firing schedule you mentioned? Thank you!

As ceramic firing vessels can retain heat and increase the temperature, you may need to fire a test piece and lower the temperature by 25 degrees if your test piece has blisters or an over heated surface.

@@moonbeammimi I tested the recommended firing schedule with a ceramic firing vessel, and the test piece turned out just fine!
@@cooltoolsvideos Excellent!! Thank you!!
Hi I've tried this twice now and every time my piece fall completely apart after the first phase of fireing what am I doing wrong?
