* shrinkage expansion after solidification: Clow136 skrinks 2x10-4. For a thickness of 2mm, that is less than 1 micron, so probably irrelvant. For Field's metal, we don't know.

* difference in expansion coefficient? Both should be very close to Al (22-23x10^-6/�C).

* difference in toxity: Field's metal does not contain lead and less bismuth
+
* fluidity: how easily does it flow? does it have sufficient capillary action to make a good film between foil and mold?
* Al affinity: how easy can we get it off?
+
* Al affinity: does it stick well to the Al during milling in its solid phase? can we easily get it off again in its liquid phase?
 
* recoverability: stuff is rather expensive (count 5 liter for final box?). how well can we recover it?
