First, try to avoid contact with perfume.
Seeds jade and ancient jade have a process of transformation, which requires human body temperature assistance. Sweat can make them more translucent. Therefore, seeds jade and ancient jade can be in more contact with sweat. Because human sweat contains salt, volatile fatty acids, and urea, etc., which can make the surface of seeds jade and ancient jade undergo a complete transformation, becoming increasingly smooth and glossy. However, new jade articles in contact with too much sweat may cause damage to the outer layer, affecting their original brightness, especially objects carved from mutton-fat white jade, which are particularly averse to sweat and grease. Many people think that Hetian jade is better when it has more contact with the human body, but this is actually a misunderstanding. If mutton-fat white jade comes into excessive contact with sweat, it is likely to turn light yellow.
