Problems solved by technology

The epidermis of nucleated pearls is delicate, and the existing conventional chemical methods cannot avoid damage to the epidermis of pearls. This damage has little effect on non-nucleated pearls, but compared to nucleated pearls with only a 1-2mm nacre layer , the damage is relatively large, and it is easy to damage the structure of the pearl

Abstract

The invention discloses a technology for processing a nuclear pearl. The nuclear pearl in sufficient light is subject to intensifying treatment, cream bleaching treatment and water bleaching treatment, wherein, in the cream bleaching treatment, oxydol in a bleaching solution has a lower content, so the damage to the pearl surface is reduced; the water bleaching treatment is performed based on thecream bleaching treatment, and a catalyst is simultaneously used to accelerate the reaction speed and reduce the reaction time, so the pearl can be bleached completely, and the damage to the pearl during the bleaching process can be minimized. The treatment process is reasonable and effective.

Description

technical field [0001] The invention relates to a pearl processing technology, in particular to a nucleated pearl processing technology. Background technique [0002] Freshwater pearls are divided into non-nucleated pearls and nucleated pearls. Freshwater nucleated pearls are usually round beads with a diameter of 4-5mm taken from mussel shell materials or other materials forcibly planted on the connective tissue of pearl oysters. Long-term wrapping (generally more than one year, and the thickness of the pearl wrapping layer is about 1-2mm), resulting in its appearance being the same as that of natural pearls. The epidermis of nucleated pearls is delicate, and the existing conventional chemical methods cannot avoid damage to the epidermis of pearls. This damage has little effect on non-nucleated pearls, but compared to nucleated pearls with only a 1-2mm nacre layer , the damage is relatively large, and it is easy to damage the pearl structure. [0003] The existing pearl p...
