At present, most of the thermos cups on the market are made of stainless steel, and the other thermos cup is made of glass. Generally speaking, as long as it is a regular production mug, it is harmless to the human body, but we must say which one is more harmless, that is, the glass mug will be safer.
Because glass is a very stable substance, that is, the bad impurities contained in it will not leak out in the production process. The stainless steel of stainless steel thermos cup is a metal compound, and the substances contained are all relatively active substances. Some impurities will inevitably appear in the production process, which is harmful to human body.
The stainless steel thermos cups produced by regular manufacturers are made of materials that meet national standards and are generally harmless to the human body. However, some inferior stainless steel thermos cups will inevitably appear in the market, and such thermos cups cannot guarantee whether they are equally safe.
