<< I guess this thinner alu pot wouldn't have such a good heat transfer ? >>

Actually the thinner one will transfer heat more easily, but the thicker one will spread the heat more as it passes through the metal. My Ti skillet [evernew] is only 10 thousandths thick.

<<Also tried it with my canister stove and it got me a nice rainbow colored spot in the middle of the hard anodised pot. Is this normal ?>>

Yes - the pan is a bit scorched. You can clean it and avoid it happening by keeping liquid water in the pan when it on the stove so the metal doesn't get up to the temperature of the flame. But it doesn't hurt anything - clean with sand or scouring powder. <img src="/forums/images/graemlins/cool.gif" alt="" />

You might be sorry. Its like the reason I carry metal fork - it doesn't melt. Buy pans with light fold out handles instead. <img src="/forums/images/graemlins/laugh.gif" alt="" />
