Glass pressure cookers are not commonly available or recommended due to the risks associated with using glass under high pressure and heat. Glass is more prone to cracking or shattering when subjected to rapid temperature changes or pressure, making it unsuitable for pressure cooking applications.
Pressure cookers work by trapping steam inside a sealed pot, raising the pressure and temperature to cook food more quickly. The high pressure generated inside the cooker places significant stress on the container. While traditional pressure cookers are typically made of materials like stainless steel or aluminum that can withstand the pressure and heat, glass is not suitable for such use.
Using a glass container as a pressure cooker could lead to catastrophic failure, causing the glass to break or shatter, potentially resulting in injury or property damage. Therefore, it is crucial to use pressure cookers designed and constructed specifically for this purpose, using appropriate materials that can withstand the required pressure and heat.
If you are in need of a pressure cooker, it is advisable to choose one made from a suitable material like stainless steel or aluminum, which are commonly used and known for their durability, strength, and ability to withstand pressure and high temperatures.
