Why are there black spots on the silver cup?
The black spots on the silver gilt cup might be due to the chemical reaction between the coloring matter, tea oil, scale, and other substances in the tea with the silver, causing black spots on the surface of the silver cup. At the same time, if it was not cleaned for a long time or used incorrectly, it might cause the silver cup to turn black. Although the silver-plated cup had good anti-oxidization properties, it might be eroded by air, light, moisture, and other substances during daily use, causing partial oxidization on the surface, resulting in a slight blackening.

Hetian jade is full of silver spots
Based on context alone Hetian jade is full of silver spots flashing may be due to the following circumstances. From the structure and composition of Hetian jade, some Hetian jade contained mineral impurities. If the fluid was a mica-like mineral or other small crystals with a metallic luster, it might appear like a silver dot. For example, when Hetian jade contained tiny pieces of mica, the crystal structure and optical properties of the mica would cause it to reflect light at a specific angle of light, looking like a silver dot. Another possibility was that it was a substance introduced during the processing of Hetian jade. For example, during the polishing process, if extremely fine metal particles were accidentally left and attached to the surface of the jade, it could also cause the visual effect of this silver flash, but this situation was relatively rare. In addition, from some situations in the market, there may be similar phenomena in artificially processed Hetian jade. For example, some Hetian jade that had been dyed or filled might react with the chemical substances or filling materials used in the process, forming a special optical effect. However, this kind of processed Hetian jade did not meet the quality standards of natural Hetian jade. " Fairy Dream of Tang Shi: Fate of Peony " is equally wonderful.

There are black spots inside the jade
The black spots inside the jade were caused by the free color-causing metal elements that seeped into it during the long process of its formation. To be precise, the black spots were the remnants and illusions of chromite after it was replaced by jadeite. They could be regarded as residual coloring elements. They were often green under strong light transmission and black under reflected light. They were usually isolated and scattered. According to the size and shape of the black spots, there were different names for them. The black substance was small and the spots were far apart. It was called a black spot. The larger one was called " fly feces ". The one with shining characteristics was called a black star. The one with a package was called a sand nail. The fewer the number of black spots and the smaller the size, the smaller the effect on the jade. Under the same texture conditions, the value of jade without black spots would be higher than that with black spots, but jade with black spots was not inferior. Some merchants claimed that it was impossible for the black spots to disappear with time, because the formation process of jade could be as short as thousands of years or as long as hundreds of millions of years. People only wore jade for two or three hundred years, and the changes could be minimal. Some finished jades would be waxed to cover up small flaws such as black spots, but as the wax fell off, the black spots would be revealed again. Moreover, some jades might have more black spots after being worn for many years because the wax fell off to reveal more black spots. The denser the green, the more transparent the texture of the old jade, the more likely it was to have black spots. Some small black spots would be covered by the dense green.

Using a cup of water to distinguish between real and fake silver
Here are some ways to identify real and fake silver with a cup of water: 1. ** Determination of thermal conductivity **: Pour a little boiling water into the bottom of the silver cup and touch the silver-containing part of the cup. If you feel hot immediately, it means that the purity of the silver in the cup is above 80%. It is not a silver-plated product. 2. ** Observe the reaction after contact with water **: Drop a drop of bleacher on the silver cup liner and carefully observe the changes on the surface of the silver liner. If the silver lining immediately darkened or blackened, the silverware would be purer. 3. [Check if it is magnetic. Take a magnet and place it on the inner wall of the silver cup. The magnetic one is fake, and the non-magnetic one is real.] Pure silver did not form a magnetic field. On the contrary, most of the fake cups were made of stainless steel + plating, so they were magnetic. 4. [Listen to the sound: Put a one-yuan coin into the cup and listen to the sound. If the sound is low and not loud, you can basically judge that it is pure silver. On the contrary, if it is clear and loud, it is a silver-plated cup.] It should be noted that these methods are only some simple identification methods, and there may be some errors. If more accurate identification is needed, it is recommended to seek the help of professional institutions or personnel.
