Abstract

The invention discloses a technology for polishing pearl, which comprises the following steps that: (1) in sufficient sunshine, pearls to be processed are selected, cleaned and dried in the air; (2) expansion treatment: the pearls obtained in Step (1) are put into an expansion agent prepared by benzene and ammonia and soaked for 40 to 50 hours at the temperature ranging from 14 to 17 DEG C, rinsed and dried; (3) dehydration: the pearls after the expansion are soaked in methanol added with a restoration auxiliary agent at a the temperature ranging from 20 to 25 DEG C for 48 hours, rinsed and dried; Step (2) and Step (3) are repeated alternatively for at least one time to complete the polishing technology. In the invention, the expansion technology and the dehydration technology are repeated alternatively so as to realize the ideal polishing effect at a lower temperature on the condition of the minimum damage to the pearls under lower concentrations of expansion solution and dehydration.

Description

technical field [0001] The invention relates to a pearl processing technique, in particular to a pearl enhancement technique. Background technique [0002] Cultured pearls are not born intact. During their growth, organic impurities such as free cells of the mother oyster, secreted mucus, and necrotic parts of the mantle are wrapped between the nacre and the bead nucleus or between the thin layer of the pearl and the thin layer of the pearl. Among them, more than 90% of the pearls directly obtained from the mother-of-pearl are dirty beads with different degrees of black spots, which seriously affect the luster of the pearls. Therefore, the pearls must be treated before they can be used for decoration. [0003] The structure of the pearl is relatively dense, and the structure of the ring layer is obvious. Under normal circumstances, it is difficult for the bleaching solution and dyeing solution to enter the inner layer of the pearl. It needs to be puffed with a puffing agent ...
