Pearl powder is a powder made by grinding pearls.

Pearl powder:

Refers to the powder made from the innermost part of pearl oyster, which is similar in composition and efficacy to pearl powder. In order to obtain nacre, it is necessary to remove the cuticle outside the shell and the prismatic layer in the middle (* * * calcium carbonate is calcite structure), and the best one is to physically grind off the outer layer and the middle layer as raw materials. But the reality is that many factories only use NaOH and other strong alkaline substances to remove the cuticle outside, crush it, and claim to be pearl powder. This category is the most difficult to distinguish.

(4) How to distinguish? Is pearl powder necessarily better than pearl powder?

Actually, the ingredients of pearl powder and pearl powder are basically the same.

Seawater pearls are basically a layer of powder.

Seawater beads are nucleated and cannot be ground.

Therefore, the inner layer of pearl shell is selected for grinding, and its substance and composition are the same as those on the surface of seawater pearl, because the substance on the surface of seawater pearl is the substance that pearl shell spits out the inner layer of shell.

Many people don't know. Why is this? What's the difference between them? In terms of effect and function?

Pearl layer powder is the powder scraped by the gray film inside the pearl shell, and pearl powder is the powder made by grinding pearls.

The film on the surface of the pearl is actually the layer in the pearl shell. Because the pearl culture time is different, the film thickness on the pearl surface is also different, and the film thickness on the pearl surface is thin when the time is short.

Due to many reasons during cultivation, the inner layer of pearl shells is generally thick, so pearl breeders put pearl cores into pearl shells and then put them into sea water for cultivation.

After a period of cultivation, the pearl oyster continuously spits out a layer of liquid into the inserted nucleus to wrap the pearl nucleus, thus forming a pearl, and the composition of this liquid is actually the same as the membrane inside the pearl oyster, so the surface substance of the pearl is the same as the inner layer of the pearl oyster, so it is powder after grinding.

However, due to the different growth conditions of tens of millions of pearls, some pearls are not very long and round enough. . . . Therefore, to be eliminated, these cannot be wasted (it has been close to farming for a long time)

So grind these pearls into powder to make pearl powder. Pearl powder is made of pearls that cannot be practiced as pearls. Think about it. If a round or better pearl is made into a necklace, it costs more than 100, and it costs only a few grams to buy a few dollars to grind it. Therefore, the pearls ground are generally inferior pearls. Don't think that nacre powder is worse than pearl powder.

Because the seawater pearl is generally 1 pearl, Baker keeps a pearl, and the pearl shell is large in volume and thick in layer. After taking out the pearls, ask the baker to grind the inner powder.

The period of pearl layer powder is generally the same as that of pearl powder, but in some periods, the seawater temperature is very suitable, and the pearl shell is cultured for a long time and the inner layer is thick, which makes the content of trace elements in the inner layer of the pearl higher. However, if some pearls die after three months, they will be taken out, so that the surface of the pearl will be thin, the thin powder will be less, and the content of trace elements in the components will be less, so the pearl is not necessarily better than that after pulverization.

By comparing the two materials, we can know that there are many pearl powder materials, so the production cost is low, but the components are basically the same, and the key to judge its quality is fineness.

1: One of the differences between seawater pearls and freshwater pearls: the presence or absence of nuclei and the level of nutritional value. The value of seawater pearls is many times higher than that of freshwater pearls.

2. Seawater beads are nucleated, so they can't be completely ground.

2. The cost of polishing after core removal is extremely high, and it is impossible to produce on a large scale.

3. Layer powder is similar to pearl powder in composition, with the same efficacy and wide sources of materials.

4. Seawater pearl powder has high medicinal and cosmetic value.

5. Because the surface substance of seawater pearl powder is the same as that of seawater pearl, the key of seawater pearl powder is the manufacturing process and fineness. This is the difference in price.
