[QUOTE="Edy, post: 122608, member: 4491"] When i started to see the alloys cylinders getting very red just before they lose their cylindrical shape i get out my ring from the oven and put it on centrifuge while keeping the flame at a safe distance from the alloys not to over heat them while i am taking my ring from oven , by that time the alloys start to lose shape and kinda look waving from the torch pressure , that the right time to ensure all of the alloys lost shape and in some cases of metal companies they unite all together , from there a few more seconds and i release..beofre that , my mistake was that i was waiting too much with torch until alloys were like liquid , then i was burning my alloys and all troubles came after that , thanks to the friends on this site i solved that .
