carmatic

hey guys, i am planning on buying some pieces of bismuth, as well as machining a disc of aluminum so that there is a hollow circular 'canal' which goes concentric on the disc

aluminum has a melting point of 660.32 degrees celcius, for bismuth it is 271.5 degrees celcius

i also have a very powerful blowtorch ...

is it possible to simply dump the bismuth pieces into the 'canal' , melt them and then let them fill up the 'canal' ? will molten bismuth do anything to aluminum?

most importantly, will aluminum do anything to molten bismuth which will affect the diamagnetic effect of bismuth, since it is part of a magnetic levitation setup i am trying to build
