Human: I am trying to find out what is the difference between a crockpot and a pressure cooker? Assistant: 
The primary difference between a crockpot and a pressure cooker is that a crock pot relies on low temperature cooking, while a pressure cooker uses high temperatures and sealed airtight containers. Crock pots are usually made of ceramic or stoneware materials, whereas pressure cookers are typically made from stainless steel. Pressure cookers also have a valve that allows for more precise control of the pressure inside the container.
