Problem with heated aluminium. Answered
i make balls of aluminium rings from chainmail technics and in a test phase i filled those balls with kevlar, which is being used by the jugglers round here. So, aim was to make burning juggling balls from chainmail. I used aluminium cos it conducts heat very well, so that ppl hardly would get burned from juggling with these balls.
Problem is, that the aluminium became rough and prim and the rings started to split shortly after the ball was being set on fire.
I dunno bout forging, but is there a way that i can keep the aluminium rings away from this effect (tempering?)? Is there a way to light up such balls without damaging the rings?
