Solder pot is a ceramic cup usually about 2" across and about 2" deep
with a heating element around it.  Filled with solder and the usual 
use is to tin stripped leads.

I've done that, you really need a heavy heater to do 
the job and it's still possible to cook the part and 
or the board.

I've been stripping boards and TV chassis (back when 
they were tube) for 40+ years.
