Turquoise disk play experience:
[TOP1] Turquoise distinction: 1. raw ore, 2. waxing 3. dipping, 4. injection, these are true. The ore is not optimized during the processing, it is the most natural, depending on which level you are. 5. Synthetic turquoise, which is the fake turquoise that we all say, can be distinguished by a lighter.
[TOP2] True and false identification of turquoise: 1. Soak, put the water into the original mineral with the color gradually deepening with time, the discoloration is not obvious, the original ore is high porcelain or micro-dipped. 2. According to the purple light, it is irradiated with ultraviolet light, and the fluorescent one is dipped or glued. 3. Fire, optimized is not to see the fire, use a lighter to burn the original shape.
[TOP3] Gelatinized turquoise & microscopic resolution: Injection molding is to put the lower density turquoise into the pigmented glue, warming and pressing, so that the colored glue is completely immersed in the pores of the turquoise. To make the density higher and the color look better; the micro sputum is to put the loose stone with higher density but poor porcelain into the transparent curing glue, but the surface has a layer of glue, and the others have not changed. It is easy to distinguish from the color, the color is natural, and the glue color looks good but looks dull. I hope to help the turquoise lovers.
The specific operation method of soaking water identification: First, the turquoise has iron wire. The iron wire we see is actually a cross-section. If you open it along the iron wire, you will see a layer of black sandwiched between the turquoise. Because there is an iron wire, it makes the turquoise more fragile, and you should pay attention to try not to bump it.
The hardness of turquoise is relatively large, and the hardness can easily leave scratches on the glass. The fingernails with low hardness can be pulled, and some even break with a hand. Turquoise has tiny pores that absorb and break into moisture. Because of this characteristic, the high hardness yield is small, and it is a pity to throw away the low hardness. Then there will be enamel glue and glue injection, which will make the production rate of pine stone higher and the finished product more beautiful.
The identification of turquoise, the experience is very important, and the theoretical practice is carried out together, which is more helpful to understand the turquoise.
The main points of turquoise identification are: 1. Identification of soaking water; 2. Photograph of purple light; 3. Burning.....etc. I am keen on the identification of soaking water. Soaking water does not damage the turquoise itself. I personally think it is more accurate. Specific operation method: waterline identification: half of the turquoise is soaked in water, half of which is exposed to the water surface. As time goes by, the part that is soaked in water will absorb water and the color will gradually become darker. This method is suitable for loose rock with low hardness.
Bubble identification: Put the turquoise into the water completely. Do not touch the turquoise after the water is discharged. Do not shake the container. In short, do not move the test article. It is best to do it at night and see the effect the next day. There will be small bubbles in the ore, and there is no bubble in the rubber and glue.
