After the water is boiled, the bicarbonate in the water begins to decompose into calcium carbonate or magnesium carbonate, which precipitates out of the water in the form of crystal particles, forming white sediments, usually called water slag, scale and soda water.
The electric kettle is made of stainless steel. Generally speaking, qualified stainless steel products of electric kettle are made of 304 stainless steel. This stainless steel has high nickel content, low manganese content and excellent corrosion resistance. It is an internationally recognized food-grade steel. Regular manufacturers will print symbols 304 on the inner and outer walls of the container.

Precautions:
1. Don't drink freshly boiled water: Some users can't wait for the water to boil before pouring it. In fact, they don't drink freshly boiled water, because chlorine in tap water combines with residual organic matter in water, which will produce carcinogenic compounds such as chloroform. It is suggested to open the lid of the boiling water container when the water is about to boil, boil the water for 3 minutes, then turn off the fire, and then leave it for a while before drinking.
2. Don't drink boiled water repeatedly: Some users use electric kettles to boil water. Because the water was not finished the second time, the remaining water was still in the kettle, and it was burned when they wanted to drink it next time. In fact, this kind of boiled water is not drinkable. Because a large amount of nitrite reacts with human blood to produce methemoglobin, which makes the blood lose its oxygen-carrying ability, thus causing people to be poisoned by hypoxia, and drinking too much may cause cancer.
3. When operating, you can't think that the water is boiling just because the water surface is about to boil. In fact, the water quality is relatively toxic at this time. Therefore, for this kind of water that is not completely boiled, it is still necessary to boil it for a while before drinking it, so as not to affect your health.
