	It seems to me that a nice thick coffee mug is the proper design
because, when the coffee is 1st poured it is too hot to drink.  The large
mass absorbs a lot of the heat quickly cooling it down to a drinkable level.
After that, the thick walls of the cup insulate the coffee so that it doesn't
keep on cooling quickly.  Is this right?  Maybe a coffee cup has to be made
with the walls in two layers.  The inner layer being thermally conductive
in order to absorb heat quickly, and the outer layer insulative.
