Jade can be roughly divided into two kinds, nephrite and jadeite. Most of what we usually see is nephrite, and jadeite is what we call jadeite.

Yu Pei is generally nephrite. First, learn about the chemical composition of nephrite. It is hydrated calcium magnesium silicate, its hardness is generally below 6.5 (diamond is 10), and its toughness is excellent. Judging from its chemical composition, it will not produce a chemical reaction when it meets water, which means that wearing a Yu Pei to take a bath will do little harm to Yu Pei.

However, Yu Pei should not be allowed to approach the strong acid and alkali solution at ordinary times, which will corrode Yu Pei.

Strong acids will corrode Yu Pei.

Therefore, it is no problem to wear jade in the bath, but jade is also afraid of the corrosion of strong acid and alkali, so it is necessary to avoid contact with these two substances.

The chemical composition of jadeite is sodium aluminosilicate with hardness of 6.5-7. It will not react with water, but it will damage jade with strong acid and alkali.

Jade is not only beautiful to wear, but also has a good health care function.

First, according to Compendium of Materia Medica, "Jade pieces are made of jade. It smells sweet and nontoxic. Indications for removing stomach heat, dyspnea, thirst quenching, beans and other debris. If you take it for a long time, you will be healthy for many years. It can moisten the heart and lungs, help the voice moisten the throat and nourish the hair. Nourish the five internal organs and stop fidgety. Gold, silver and Ophiopogon japonicus are beneficial together. " It can be seen that jade was not only used for viewing in ancient times, but also played a very good role in medical care.
