A stovetop pressure cooker. A pressure cooker is a sealed vessel for cooking food with the use of high pressure steam and water or a water-based liquid, a process called pressure cooking. The high pressure limits boiling and creates higher temperatures not possible at lower pressures, allowing food to be cooked faster than at normal pressure.
Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans). Canning provides a shelf life that typically ranges from one to five years, [a] although under specific circumstances, it can be much longer. [2]
Pressure canning is the only safe home canning method for meats and low-acid foods. This method uses a pressure canner — similar to, but heavier than, a pressure cooker. A small amount of water is placed in the pressure canner and it is turned to steam, which without pressure would be 212 °F (100 °C), but under pressure is raised to 240 °F ...
An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or compressor, cycle. The indicator diagram is used to calculate the work done and the power produced in an engine cylinder [2] or used in a compressor cylinder.

Airtight vessels to apply pressure as well as heat are called autoclaves. In the food industry, pressure cookers are often referred to as "retorts", meaning "canning retorts" for sterilization under high temperature (116–130 °C). Retort in use
After Mason's patent expired, many other manufacturers produced glass jars for home canning using the Mason-style jar. [9] Early closure style, zinc lid over glass liner. The initial form of closure for the glass canning jar was a zinc screw-on cap, the precursor to today's screw-on lids.
