Is the medical stone liner better or the shaped kettle better?

The medical stone liner is good. Medical stone has the characteristics of high temperature and pressure resistance, corrosion resistance and impact resistance. The inner container of the energy-gathering kettle adopts coating technology, and the material is roughly the same as that of ordinary rice cookers. The medical stone liner can withstand the impact of high temperature and high pressure, wear resistance and chemical corrosion resistance. The inner container of the energy-gathering kettle is non-toxic and coated with diamond particles to reduce the phenomenon of sticking to the pot. The medical stone liner can keep the original flavor of food.
