Interesting discussion.
The observation that there might be a difference in thermal inertia between
processing solutions warrents more discussion...
Unfortunately it will not be taken up by myself.
Curiously, if money is not a problem, diamond would be about the best barrier
for liquids you were trying to bring to the same temperature quickly... gold or
silver would also be quick heat transfer-ers...
unfortunately, money is a real "barrier" here when it comes to using
one of these methods!
