Experiment: Hadar's Quick Fire Clay - Copper on a Lampwork Bead
Metal Clays - if you haven't been paying attention - have come a long way - with quite a few competing brands and more options than just Fine Silver anymore.
This is a fine powder - you mix it up yourself - from Hadar Jacobsen.
I poured some into a frit tray, made a white bicone, and then rolled the bead in the clay powder.
It needed a lot of heat to get it to stick - much higher than just getting frit to stick to a bead.
Heating the copper clay powder after applying it to the bead made the copper powder go black - no surprise there.
I then encased it, and finished shaping it, and kilned it.
Two observations: One is, I got pretty colours - intense dark reds and some purple blue.
PS. I don't know if it gives off toxic fumes. It's didn't smell particularly noxious - but that's not much to go on. It flared up and burned with a greenish flame at one point when I applied it to the bead, but not for more than a half-second. But the point is, I don't know if what I did was stunningly unsafe - if you choose to try this or other things like it - you do so at your own risk.
