oh.. i read someplace a while ago can get diff colour burns also..?
With titanium the colour seems to be dependant on how hot you get it...if you heat it to cherry red it goes the deep purple colour, or blue fading to orange and the yellowy straw colour where it\'s been coolest. It does mean that the welds on titanium (which I gather is ****ing hard to do!) are objects of great beauty! This is my one, seems a shame to stick it underneath a car, really....
Didn\'t know that it worked on stainless, though I should\'ve twigged, really, since the collector on my bike\'s started to do it all on its own accord! :Giggle
