Stock Pot
From Wikipedia, the free encyclopedia

A stock pot is a very large and deep cooking vessel generally used on top of a range for making stock or soup.

Stock pots can be made of a variety of materials, like aluminum and stainless steel, As with all pans the heavier the gauge of the metal the better (especially at the base); it enables more even heat distribution, which makes sticking and burning less likely. Some stock pots have a thick sheet of thermally conductive aluminum laminated into their base for that purpose (like the one shown). A coating of copper on the base allegedly has the same effect, but it would need to be reasonably thick to have any real benefit.
