Are you sure? How do you get a higher melting point metal to melt at
313F?
Seems to me the tin and bismuth would just sit there in a puddle of
indium.

Now I wonder if one melted the tin with the bismuth, what that alloy would
melt at.

The higher melting point metal can dissolve in the molten lower melting
point one. Just the same way that sugar dissolves in water. It hadn't
occured to me before until I asked a guy that made pewter how they go the
copper into the mix when it melts above 1000C IIRC and tin is about 300C.


Thanks!!
