Is Corning glass jar harmful?

Food should be put in a clean glass pot or aluminum pot, and there should be no peculiar smell in the pot. Can't use a copper pot containing a lot of copper ions, stainless steel pot containing a lot of nickel-chromium ions, ceramic pot containing a lot of enamel, and an iron pot containing a lot of iron ions; Don't use modern casserole either, because the sand in modern casserole is not particular about material selection and contains many harmful impurities; Therefore, under the action of hawthorn fruit acid, these harmful impurities will become water-soluble ions, resulting in toxicity. Of course, aluminum pot is not ideal, because it contains aluminum ions, which may promote arteriosclerosis, but it does not cause cancer. Of course, it is best to use glass pots, but in some countries' markets, there are no large glass pots. Therefore, mass production of large glass pots is very necessary.
