I am making a series of rings that will hold Polymer clay in a bezel. I am going to be writing a tutorial for a magazine. The shaft is PMC Pro and the bezel is PMC3. I made the shaft and and the bezel and joined them together. I fired them on an open shelf for 30mins and then put them into activated carbon and fired for an hour.
This ring is straight out of the kiln and you can see the PMC Pro is oxidised and the PMC3 is white as usual.
These are the rings cleaned up. The shafts still have to be formed around a mandrel, and I still have to decide what polymer is going in the bezel area.
