Jade is very jealous of oily greasy. If it is a high-end goods that preserves value, it is not good to wear it into the kitchen to cook. Jade is also not suitable for close to high temperatures, but not for a long time. Because of this long-term, it is easy to produce physical changes and lose luster, not so fresh. Jadeite should not be exposed to strong acid solutions, which would destroy the structure and color of the jadeite.
