The bronze pieces came out of the kiln today, but I'm just not sure about them.
Are they metal or not? They sound like metal. They look like metal. (But somewhere I read that some test pieces should be made and tested after firing. I think it said to try to break the bronze pieces with pliers after firing.) Well, I did just that and the test pieces bent and then snapped. I can't break or bend them with my fingers though. And, they didn't disintegrate in the tumbler like my last batch of copper pieces did.
They're not as pretty of a color as I expected either. I fired them in the carbon base charcoal which doesn't produce the colors that the coconut charcoal does but they still should have that buttery gold color I've seen pictures of.
The edges of the pieces that were cut with a tissue blade were fine. The pieces that I cut out with a needle tool were prone to cracking (even though I tried to file them smooth before firing. The book said the cracks would be amplified and they were!) The needle tool tended to drag through the clay, distort the shape and tear the edges. (Again, maybe it was the age of my clay.)
I still don't know if I like this clay or not. I'll give it a couple more tries (with newer clay) before I pass sentencing, but it's not looking too good.
