The measurement of jade could be done in terms of weight and specific gravity: 1. ** Weight measurement ** - ** Direct measurement method **: Use an electronic scale or balance to directly measure the weight of the jade. Place the jade on the scale plate and read the displayed value. The units are usually grams (g), kilograms (kg), or tons (t). - ** Volume measurement method ** - Volume measurement: Use a measuring cylinder or the drainage method to measure the volume of the jade. He placed the jade into a measuring cylinder filled with water and observed the rising scale of the water surface to calculate the volume. - Calculating the weight: According to the density of the jade (usually 2.95 - 3.00 g/cm 3), multiply the volume by the density to obtain the weight of the jade. - ** Formula Calculation Method ** - Confirm shape: Judge the geometric shape of the jade, such as a sphere, a cuboid, etc. - Calculating the volume: Use the corresponding volume formula according to the shape. For example, the volume formula of a sphere is <V =<frac{4}{3}><pi r ^3>> - Calculating weight: Multiply by the volume density. 2. ** Gravity measurement ** - It can be measured using tools such as densimeters and buoyancy methods. The specific gravity referred to the ratio of the quality of the jade to the water in the same body. It was a key indicator to measure the authenticity of the jade and the quality of the jade. The measurement could be done according to the principle of Archmedes. The specific gravity could be calculated by the ratio of the weight of the jade in the air to the weight in the water, and then the quality of the jade could be evaluated. In addition, the identification of jade can also be judged by appearance (such as the environment in which the jade is produced, the characteristics of the shell, etc.), the water drop method (to see if the water droplets spread on the surface of the jade), the lamp method (to see the jade's light transmission and halo), and to check the origin (a specific jade has a specific origin). However, these methods can only be used for preliminary judgment. To accurately identify jade, the most reliable way is to issue a professional National Inspection Certificate (NTCT). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
