    Identification Of Luxury: Key Points For Identification Of Red Coral

    Identification Of Luxury Goods And Identification Of Red Coral

      

     

    Key points for identification of Red Coral

    Look at

    texture

    Red coral has vertical lines parallel to the direction of coral growth and is arranged more closely.

    In addition, there are rings on the cross section of red coral like tree rings, and we should pay attention to these two textures when we identify the naked eye.

    Look at the color: the color of red coral is a vivid red. No matter it is shallow or deep, it is alive, immortal and not gloomy.

    Red coral has bright waxy luster, while the dyed red coral has no luster, and its color is also depressed.

    Listen to

    voice

    True coral looks tender, but it has a crisp and tough voice when it collides with each other. Generally, plastic or other imitation coral does not produce this hard and crisp sound.

    This sound is particularly evident on the coral like branches.

    Weight: coral has a good sense of weight. A heavy feeling which is usually placed in the palm of your hand will give people a sense of indifference. This component is also one of the bases for identifying red coral and some inferior counterfeit products.

    Identification of natural corals and coloured corals: dyed coral is usually dyed with organic dyes to dye Bai Shanhu red and other colors.

    The distinguishing feature is that the dye is enriched in the cracks, and the outer color is deep and the inner color is shallow.

    Wipe the cotton bar with acetone, and the cotton will be dyed.

    Exergy

    natural

    Identification of coral and imitation: Coral imitation products are commonly stained marble, red glass, red plastic, calcite powder and dye "Jill Coral".

    These imitation products do not have the internal structure of natural red coral. They can be discernible by careful observation of the texture. The marble is grainy, and the dye is enriched in mineral particles. The acetone test can be used to obtain the answer. Red glass can be made very similar, and occasionally bubbles can be seen. From hardness, glass is larger than coral and does not react with hydrochloric acid.
