Публикувано на от Кингджи

Because jadeite is hot in the jewelry market, the beautification of jadeite is also varied.

Glue filling treatment for cargo B is the so-called cargo B. Here we use glue instead of filling to distinguish the bottom digging and filling, because the glue for cargo B injects glue into jade for consolidation. The structure of jadeite, and the bottom digging and filling glue attaches the glue substance to the back of the jadeite without injecting it; the glue substance is poured into the jadeite, mainly to bond the jadeite structure loosely eroded by strong acid. Следователно, it needs to be filled with a strong coagulating glue. Common filling materials include epoxy resin 0pticon, AB glue, и т.н.. These glue-like substances can be detected by infrared scanning. През последните години, it has also been heard that processing companies are preventing infrared rays. Scanning to detect the filling material and using glass filling material can also improve the transparency of emerald. Обаче, it is understood that the commonly called “water glass” filling material still needs to have a resin component, otherwise there is no adhesion, so consumers do not have to worry too much, and under the gem microscope observation, it can still be seen that the processed jade structure has been damaged. , As long as you buy a gem appraisal issued by a credible appraisal office, you can avoid buying B jadeite; some jadeite is poured with resin to fill the cracks in the jade itself to strengthen the durability of the jade, so the appraiser is in During the appraisal, each part of the jade will be identified.

Heat treatment, the jadeite will become red after heating. Обикновено, the probability of heating it into red jadeite is higher with yellow jadeite. The principle of this effect is to heat the iron oxide molecules originally in the jade to evaporate the water molecules to make the red color. The color of the iron oxide molecules appears. The heat-treated red jade generally looks dry due to the evaporation of water molecules, and small cracks caused by heating may be seen when viewed with a magnifying glass.
