- This is a bit of a different video for me. Its a video about what steps I take to try figure out how to stop rough sapphires breaking when being cast-in-place.
Hopefully you find this video helpful :)
I am using Red Clay and a DIY flask made by Craig Dabler from DIYcasting www.diycastings.com/

Thanks so much kirra-Lea! This answered more questions than just the stone breaking. Watching that, I was surprised the silver even encompassed the stone on such a thin mould- but the “rolling melt” seems to be a very important point! My silver often sticks to the crucible before pouring, and in my trouble shooting, the stone would be so large that I imagined it was drawing heat away from the silver and it would stop it in it’s tracks. Not allowing it to encompass the design- even on a much thicker band.
Choosing stones with softer edges sounds like a good plan for future attempts.
I’m sure many people will find this helpful!!
Thanks so much!
I love your passion for jewelry
thx a lot ! useful video. cool organic shaped stone setting
Warm the stone with a heat gun and see if you can get the water out
What about using a toaster oven to warm your prepared crucible? I learned this from Craig's group! Let us know if you try it!
When the metal cools it contracts and squeezing the stone but being silver ( a soft metal) I don’t know if it would have enough force to crack the stone.. I’m wondering if there’s water in the rock that creates steam and cracks the rock on its way out
Muy cuestión is., you put the stone on the sand & have the pouring the metal with the stone? And what kind stone resist heat?
