New Creative Bronze and Copper Clay
I just wondered if anyone had tried the new Creative bronze or copper clay that Cooksons are now selling, and if so what did you think? I'm interested because I like using PMC but find it so expensive, and I find the Art Clay Copper very dry and hard to work with, so wondered if this would be a good alternative.
I've used the Copper and found it quite easy to use. Even torch fired it rather than firing up the kiln. But I found that the ends of the petals on this flower seem to have whitish bits that I haven't been able to clean off yet. Any ideas? Re-pickle and polish maybe? The other pieces were fine.
That necklace is beautiful!
You could try re-pickling and polishing, but to be honest I am a novice when it comes to pmc and clay, so I'm not sure what would help. I would love to learn more about it, which is why I wanted to try the copper clay, as funds don't stretch to the silver clay at the moment.
I don't have a kiln so everything I have tried has been torch fired. How long did u torch fire the necklace for? I torch fired a piece made from artclay copper but I found it brittle. I fired it the same way as I did the PMC3 silver I tried, which was to take it to the bright orange stage and then keep that colour for 2 minutes. Do you think that it needed to be fired for longer? The piece was a solid bird approx 2cm tall if that helps.
Hi I am no expert at all with the clays but i have read that the reason for the kiln firing rather than flame is the copper that oxydises, so prevents the proper firing process. I know the new clay from Cookies says it can be flame fired, but better results are obtained by kiln. Before going ahead with a piece I think you need to experiemnt with the clay itself under different conditions. Hopefully someone with more experience will come along with better advice.

Thank you Dennis. I don't have a radial wheel (or any room to set one up if I had) but will get the polishing pads out again and have another go.
Thank you Laura. I torched the Copper for just over 5 minutes and usually do at least 3 minutes for PMC3. Any larger or delicate PMC3 pieces are done in the kiln and your bird probably falls into that category.
These are radial discs Elaine - used in a flexshaft, so no space required:
One of my most used tools.
Thanks, George, me being slapdash.
Ah yes, thank you George (and Dennis), I have some of those and will get them out to have another go at the flower.

I haven't tried the new Creative copper - my order is on its way (together with some bronze!), but I did fire the Art Clay Copper with a torch and found it needed a lot longer than said. Mine was a smallish pendant shape rolled to 1.5mm and it did need 20 mins torch firing. The first one fired for 10 mins didn't fire properly - couldn't polish it up even with the coarse eveflex wheels!
