Note: It has been noted that some CZ stones haze over when fired with FastFire BRONZclay. The manufacturer is aware of this. We suggest testing before use in a creation. This does not happen with original BRONZclay.

3 of 5 Here’s how to sinter, but DON’T add CZ’s! February 12, 2017
Reviewer: Anonymous Person  
After experimenting with firing schedules in my Paragon SC2 kiln, I found the following to work: Ramp at 1650˚ and hold at 1650˚ for 1 hour. When I did this with the prescribed test strips (4pct), I was able to bend fired pieces in a 180˚ U shape and had no cracking or bubbling. HOWEVER, I fired some white diamond CZ’s from Rio Grande in a piece and they came out with residue on the surface that I had to remove with a polishing tool on my flex shaft. And even after getting the surfaces of the stones clean, the stones appear cloudy throughout, so I don’t think this was just a surface problem. I have fired these same CZ’s in other clay: regular Bronzclay and red and white Copprclay in the same kiln and carbon and they have come out beautiful and sparkly.

5 of 5 Fun and easy! May 27, 2013
Reviewer: Karen Cagle from El Segundo, CA United States  
Wanting to try bronze clay, I bought this and have really enjoyed it.  The texture is dryer and courser than PMC but easy to work with.  I couldn't make a creamy slip with it but it joins well enough. Low shrink ( the 2 stackable rings I made might fit someone : ).  No pre-fire, but does require carbon. Very hard once fired, shine up nicely.
