Bronze clay and elusive color

Another batch of Bronze clay, into the kiln. Before and After. A few of the pieces had copper inlay, but otherwise it was all bronze.





It was interesting that the color changed depending on where the pieces were placed in the charcoal to be fired. The pieces with more purple/blue/green were in the first layer of activated charcoal. The pieces that are more yellow/gold were in the top layer of the charcoal. I don’t understand what causes one color or the other, but the golden color was consistent with the top layer, so it might have been exposed to a higher temperature.

I tried applying Butcher’s wax to one of the long “stone” pieces, to see what it would do. The color became a little muted and the piece kept picking up fuzz from my towel because the surface of the bead was rough.

I decided to brass brush the beads and go from there. But where had I put my brush? In looking in my usual spot, I couldn’t find it, but I pulled out a steel brush that I had never used. Worth a try. But then I HAD to find my brass brush to see if there was any difference in how the bronze looked depending on which brush was used. I located the brass brush, and here are the comparisons:


The steel brush was used on the pieces on the left, while the brass brush was used on the pieces on the right. I liked both of the finishes and was glad to see that there was a difference. I soldered posts on the square pieces at the bottom of the group and then used the buffer to get a brighter finish. I then used the Baldwin’s patina and I am really happy with how they turned out. ( The fluorescent light in my kitchen doesn’t give the photo quality I like, but it was night time and I had just finished the earrings below.)
