The plastic smell of inferior health pot after boiling water is very heavy, because the apron used to seal the heating plate is made of non-food grade ordinary silica gel. When the upper part of the apron comes into contact with water and is heated and decomposed by the heating plate, it will continuously release odor and harmful substances, which is harmful to human health. Regular health pots are non-toxic and tasteless, and most of them use imported food-grade silicone rings.

Most health pots on the market choose domestic high-temperature resistant high borosilicate glass, but high borosilicate glass also has advantages and disadvantages. Poor quality is easy to burst in the environment of high temperature and sudden change of hot and cold, and good quality has the characteristics of high temperature resistance, high strength, high hardness, high light transmittance and chemical corrosion resistance.
