Need some advice about Bronze Metal Clay
I recently decided to give the new bronze metal clay a try. Found it
easier to work with, consistency-wise, than instructions had warned.
Everything went well up to the firing. I fired it in the coal
medium, wanting the patina, as advertised. Programmed my digital kiln
for the right ramp time, holding time, etc. When it finally cooled
and I anxiously dug them out - they were different dark colors but it
was a really matte, thick and “dusty” finish that obscured the
designs in the pieces. I tried burnishing, buffing, etc…which took
off all the color of course, so they’re just bronze-colored now. with
a little greenish hue in the recesses. What in the world went wrong?
I dried them on a hot plate for a long time, so I think they were
properly dried. Oh, and some of the pieces that were meant to be
pairs - as in earrings - shrank at a different rate, so no longer
Any suggestions would be appreciated.
