After my Art Clay Copper experiments (see New Art Clay Copper Experiment and Copper ArtClay Disaster!), I decided to try a different brand of metal clay for copper and bronze pendants. I ordered some of the Prometheus clay made in Turkey (usually referred to as Pro clay), instead of the other brands, simply because it fires quicker and seemed easier to deal with. I was not disappointed at all! The fresh clay was a pleasure to work with, as it is so soft and moist, and very manageable. After they dried, some of the pieces looked like this:
So I wrapped them in paper towels and then bundled them up in fiber blanket to get them ready to be fired in the kiln:
I am not too fond of fiber blanket, but I wanted to try this quick method to see how hard the bronze would come out and how much oxidation it would prevent. Most of the bundles were tight, but I left a lose end on a couple of them (to measure oxidation if I fire them without the blanket). Once fired, the bronze pieces came out wonderfully hard, with a somewhat copper-ish color. As expected, the ones that had more air exposure had more oxidation than the ones completely wrapped in the paper towels and fiber blanket, but nothing excessive, which was pretty nice to see. Below are the pieces after being tumbled. You can still see the copper-ish hue they have (sorry for the bad photo, it was a very quick one with bad light).
I brushed them with a brass brush and the color changed to more of a usual bronze tone:
I love the feel of these pieces! They’re like little jewelry sculptures… I chose a blue and green patina to finish these designs:
I will have better pictures of these for the web site’s Jewelry Shop once I make bronze chains for them, and I will also share more experiments with the new Prometheus copper clay soon. Stay tuned…
