Papin pot
A Papin pot is the forerunner of the modern pressure cooker . It is a container in which the boiling temperature of water can be influenced by generating different pressures . It was developed by Denis Papin (1647–1712) in 1679 and a patent was applied for in 1681 . The pressure could be continuously regulated using a weight on a rod that was connected to an opening in the pot. When the internal pressure in the container was sufficient to lift the weight, this pressure relief valve opened . This addition to the steam boiler represented an important step in the development of the steam engine .
