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!
Thank you for this very useful video...I noticed that when you pour the molten metal remains on the surface a small flame could be the one that continues to heat the stone and ruin it? it's just an idea I'm not an expert in this technique
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

Thanks for this, it is nice to see failure and be able to trouble shooting why. Very useful!
I love your passion for jewelry
Warm the stone with a heat gun and see if you can get the water out
thank you!!!! keep the videos coming
thx a lot ! useful video. cool organic shaped stone setting
Your delf clay is very moist and keeps its shape well, mine doesn’t :( Do you have any suggestions?
thanks love

Hello! Where do you source stones like these from? Cheers!
Muy cuestión is., you put the stone on the sand & have the pouring the metal with the stone? And what kind stone resist heat?
It has to be more than 7.5 on mohs hardness scale..
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!
Craig's group? What's that?
