I have heard many discussions about the best color and surface texture of a 
piece of metal for it to radiate heat most efficiently, but nobody knows for 
sure.  I assume a bare piece of metal with high surface area would be best 
regardless of color.  Is one metal better than another?  I am talking about 
temps only up to a few hundred degrees C.
