Can I wear a pearl necklace to take a bath?
You can't wear a pearl necklace to take a shower.
The main mineral components of pearls are aragonite and calcite, of which aragonite is the most, and both mineral components are calcium carbonate (CaCO3). Aragonite has a specific gravity of 2.95, hardness of 3.5-4.0, calcite has a specific gravity of 2.7 1 and hardness of 3. When pearls come into contact with heat sources or fire sources, they tend to dry slowly, gradually lose moisture, and their physical properties are unstable. aragonite is transformed into calcite, which makes pearls gradually lose their original beautiful luster.
Why can't I wear a pearl necklace in the shower?
1. When taking a bath, pearls will encounter detergents such as shampoo, shower gel and soap. These cleaning products are often acid-base and easy to corrode the pearl surface.
2. When taking a bath, pearls will touch tap water, which contains chlorine and belongs to weak acid. Generally, when the PH value of tap water is about 4 and the pH value is less than 7.8, calcium carbonate will dissolve and pearls will be invisibly corroded. Of course, this time is longer. Generally, you may not find any obvious changes after washing pearls several times, but if the washing time is long, the "life cycle" of pearls will be shortened.
3. Except for the pearl part, the beads in the pearl necklace are difficult to dry after washing, and long-term use will cause the beads to be moldy and easy to loosen.
