Human: I'm a bit confused about the differences between a crockpot and a slow cooker. Assistant: 
A crockpot is typically made of ceramic or stoneware, while a slow cooker is usually made of metal. Crockpots are generally more expensive than slow cookers, but they tend to be easier to clean. Slow cookers can also be used on low heat for longer periods of time, whereas crockpots need to be turned on and off manually.
