Last year, I tried out Hadar’s Brilliant Bronze clay (read about it here), and even though I was happy with it, I’m always checking out different materials. So I picked up a couple jars of Goldie Bronze clay. Goldie Bronze has a Soft recipe and a Hard one, so I was interested to see the differences between them, and the difference from Hadar’s.
Both start as a powder, and need to be spritzed and mixed with water.
My little patty of clay is ready to go! I almost didn’t need to use my Slik (Cool Tools’ non-stick balm) to keep it from sticking to my hands. It’s very buttery. I did need to use it on my plastic surface though. The clay didn’t want to stick to my skin, but it didn’t want to let go of the plastic.
It’s been amazing to work with! I found I prefer the Hard recipe. It’s much easier to carve when dry, and holds its form very nicely. I can move shapes from the plastic to my polymer clay drying forms without having to worry as much about distortion.
Firing was 2 part, just like any base metal clay. First segment was at 662°F for 40 minutes on a layer of carbon (not buried) in a stainless steel container (no lid). Although the instructions say that 30 min is good, I’ve had better luck extending the firing times on both segments. The second segment was 1508°F for an 1 hr buried in carbon with the stainless steel lid on (40 min in instructions, but again, I’ve had better luck holding longer). Don’t try to pick up or move the piece between firings! It’s super delicate and will crumble if handled the wrong way. And there’s no telling what the wrong way is until it’s too late.
The bezel was a little stiff when I was setting the purple tourmaline, so perhaps I should have made it out of Soft Goldie Bronze instead of Hard. Not sure if there’s a difference once they’re fired, but that’s a test for another day.
