How are stockings made?

A stock is made a couple of different ways, but always with the same basic technique. In a nut shell it is by filling a large "stock pot" with animal bones (chicken, veal, beef, lobster, fish... Etc), mirepoix (aromatic vegetables - carrot, celery, onion), garlic, bay leaves, black peppercorns, and water, and allowed to slowly steep the proteins and flavour out of the bones into the water. This is done over the course of several hours, paying close attention to never let it boil.
