Although the color-changing mug will use color-changing powder and auxiliary materials to treat the ceramic embryo, because the color-changing mug is in direct contact with food, the manufacturers of general household brands will pay attention to the safety of these materials.

Most of the materials used in color-changing mugs have passed the domestic inspection, ITS, SGS and foreign inspection, as well as the FDA inspection of color-changing mugs. If all the above tests pass, then these mugs are non-toxic and lead-free, and will not cause harm to human body.
