How about the safety and hygiene of the kettle?

304 stainless steel or glass or ceramic kettle is safer and healthier. 304 stainless steel kettle or glass ceramic kettle is safer and healthier. In the manufacturing process, after high temperature treatment, harmful substances have volatilized, and the glass has high safety, high temperature resistance and good thermal conductivity. Ceramic materials have a wide range of uses, such as acid resistance, alkali resistance, oil resistance, high temperature resistance, low temperature resistance and high safety. Compared with aluminum electric kettle, stainless steel electric kettle is made of "high manganese steel", which meets the product requirements, has stable structure, is not easy to rust, and will not precipitate carcinogens such as heavy metals at high temperature. Compared with stainless steel electric kettle, glass electric kettle has no risk of heavy metal poisoning. Therefore, whether it is a stainless steel electric kettle or a glass electric kettle, there is not much problem in hygiene. But there is a difference between stainless steel electric kettle and glass electric kettle in use. Stainless steel electric kettle boils water for a long time, and metal ions and impurities in the water are easy to combine to form scale, which is difficult to clean. But the thermal conductivity is better, the water runs fast, and it is strong and light. Glass electric kettle need not worry about scale, cleaning is simpler, glass material is transparent and beautiful, suitable for friends who have certain needs for appearance. But the thermal conductivity is poor, the boiling speed will be slow and heavy, and it is easy to fall.
