Must for joining no fired and fired pieces

"excellent choice for fire bronze clay in kiln,. Do not alter the cz, keeps color and clarity. Thank you"

— Bernardo H. (5/5)

Maintained color in firing

"I found the best way to fire this CZ (blue topaz) was to set into silver clay, do a burn out on open shelf ramped to 650 degrees F for 40 minutes, let cool in kiln, bury in carbon and fire at 1475 F for one hour. Rhonda from Cool Tools was a great help when I emailed about my first failed attempt firing on an open shelf only and the stones turned dark red. I did use the low fire Phoenix PMC which was recommended but I think other silver clays will work if you follow the steps above unless it’s a piece that needs a higher temperature firing like 1650 F for two hours. Not sure about that. For my earrings, the lower temperature worked fine."
