Thank you everyone for all your advice. I work on a minor torch on a 5lt oxycon.
I think your all correct in that I’m working far to close to the tip of the torch. But these opalinos are extremely sensitive to picking up discolouration from unburnt fule..... sigh!
Is it worth continuing with the colours that the question!
When the colour stays true they make rather lovely hollow beads 😊
Once again thank you all very much for the advice.
Kindness
Tasha.
