The Ideal Pressure Cookware Should Be Made From A Non-Toxic Material

Unglazed primary clay or pure clay is a naturally inert material that can be harvested from earth's surface. It has absolutely no metals or chemical toxins. If no glazes are used, it can make a 100% non-toxic cooking pot that is ideal for pressure cooking. Pure Clay has been used for making cookware for ages until a few decades ago when metal cookware came into practice.
