If the coating is stable, thick and hard enough, you can choose the upgraded medical stone pot and non-stick pot. The advantages are that the ingredients are not easy to stick to the bottom of the pot, the cooking process is more labor-saving and fuel-saving, and the later cleaning is more convenient. But the medicine stone pot is not all stone, but also made of various materials by die casting. I think it is more durable than Teflon. Some products claim that they can directly fry their nails with a shovel. After all, the ordinary non-stick pan can only carefully turn the food in the pan with a wooden shovel, a bamboo shovel or a silicone shovel. Although the coating of medical stone is stronger in theory, I think it is better not to be too presumptuous. Some medical stone pots are fake, but they are made into a common "fancy" coating with the texture effect of stone particles, even metal texture, as thin as flash diamonds. God knows what it is, but merchants also call it a medical stone pot. You can compare different products face to face. As for which is better than the iron pot, I think if we consider the cost, we will choose the iron pot. Iron pots are resistant to tossing. If it burns black, wipe it with steel balls. No matter how strong the coated pot is, it dare not do so. Moreover, the coated pot will break down in a few years, and the barbecue is dry. This kind of internal heating without water injection will be uneven, which will lead to different expansion coefficients of various parts of the pot and the coating will easily fall off. But the new medical stone pot is really cool to use. If you are lazy and have enough money, you can buy a medical stone pot, at least experience this silky touch, and your sense of quality of life will be improved.
