19/01/2019 - Broken Stones
This project has not been without it's casualities.
I've broken 5 stones in total. One was dropped, 3 were dropped whilst in a plastic container and one cracked as I flared open the rear tube to secure it into a full casting pendant.
I have therefore realised that the donut shape is quite fragile. A cabochon of this size, would end up much thicker in the centre, and would therefore be much stronger. The ones with the hole off-centre are particularly fragile because one side ends up much thinner.
Is this why donuts are so cheap? They are thinner overall and use less material?
