OK, I am so slack I still haven't managed to take a pic of the beads i made that turned out well, so here they are. Not really sure what I did differently between these & the earlier ones with the shards that turned to mud but if I work it out I will let you know!
ETA - one thing I do know is that I didn't do anything like Jed's video, from memory I just turned up my propane & waved it around in the flame about half way up.
