A Hamilton Beach crock pot works by heat conduction from the base to the vessel. The base contains heater bands whose temperature is set by the control buttons on the front of the unit. The vessel holds the food and is made of stoneware for constant and evenly distributed heating.
The heat from the base slowly spreads from the bottom of the vessel up the sides to evenly cook and heat the food within. The food is placed within the vessel and covered with the lid to hold in heat. The timer and heat levels are set, and the crock pot controls the cooking process precisely.
