  1. A total of 5 o'clock, take a closer look!
    1. The removal of dust should be cleaned to the dust and dirt of gold jewelry. The easiest way is to brush gently with a soft brush dipped in hot water. Scrubbing, but cutting should not be scrubbed with wear -oriented particles (such as toothpaste, polishing paste, fine sandpaper, or fine sand cloth, etc.) to avoid reducing the weight of the gold and causing losses.

    2. When washing the pure gold necklace of the pure gold necklace, the pure gold necklace should be placed in the container, and then water is added to the container, and a small amount of ammonia water is added. Then the mouth is tightly covered, shaken back and forth, and then removed. When wearing a golden necklace, it should also be maintained with a buckle switch, and regularly drops a sewing machine oil to the switch to prevent the miniature spring in the switch rust.

    3. The removal of gold jewelry white spots contains micro -mercury (mercury) in the commercially available cosmetics. For example, there are often phenyl hydroxyl mercury and skeleton meal chloride in the freckle cream. White spots or whiteness will appear after the gold jewelry is contacted. At this time, do not scrape or sandpaper with a small knife. As long as the white spots or white jewelry appear to bake in the fire, and then wipe it with a soft cloth, the gold jewelry will restore the original luster.

    4. The surface dirt cleaning gold jewelry on the surface will be dull. At this time, you can use the flushing photos of the photo of the photo to flush it with the warm water from 30-40 ~ C, and dilute it with double the water. After soaking the dirt's gold jewelry for 4 to 6 minutes, use soft hair to use soft hair, then use soft hair. Wash the dirt and rinse with water several times. If you use fine woolen to dip the nail polish, the jewelry will be brighter.

    5. Take warm water (40 ~ C) 1000 ml of warm water (40 ~ C), add 200 ml of methamphetamine to make a water solution, then put the gold jewelry into this cleaning solution for 10 minutes, then brush it with a brush, and then rinse it with water.

    . If you take it to the gold shop, you must pay attention to the following three points:

    . To choose a regular jewelry store, it is best to go to some large -scale and credible places, or check the qualification certification and business license of the jewelry store;

    . It is best to understand the exact weight of your jewelry before cleaning, and record the weight. After processing, you must go to other departments in time and then call meter. When cleaning the jewelry, if the pungent smell is emitted in the solution, it is "Wang Shui". Remember to be careful to avoid losses;

    three. It must ask for bills after paying the fee.

    In the brief introduction of "Wang Shui" is what "Wang Shui" is

    Wang Shui is also called "king acid", which is a very corrosive, yellow smoke The liquid, it is a mixture of nitric acid and hydrochloric acid, where the mixed ratio is 1: 3. It is one of the few substances that can dissolve gold and platinum. This is also the source of its name. However, some very inert metals, such as, are not corroded by king water. Wang Shui is used in the etching process and some analysis. Wang Shui quickly decomposed, so it must be made directly before use.

    One of the king water

    The king water is a mixture of thick HNO3 and thick HCL. The volume ratio of thick HNO3 to hydrochloric acid in the laboratory is 1: 3 formula

    HNO3 3HCL = 2H2O CL2 NOCL
    n A series of strong oxidants such as isl, as well as high concentrations of chloride ions. The oxidation capacity of Wang Shui is stronger than nitric acid. "The King of China. The reaction equation of Wang Shui dissolved gold and platinum is as follows:

    auo3 4HCl = H [AUCL4] NO 2H2O
    n3pt 4HNO3 18HCl = 3H2 [PTCL6] 4NO 8H2O

    The colorless liquid of the two of the king water

    Because it can dissolve other precious metals such as gold and platinum, the alchemy warlock is named Wang Shui. It is extremely corrosive, has a smell of chlorine gas, and is unstable in nature. It is prepared before use.

    Min and platinum are not soluble in a separate concentrated nitric acid and dissolved in the king water, mainly because the king water not only contains nitric acid, new ecosystem chlorine and chloride nitride:

    HNO3 3HCL = NOCL 2CL 2H2O

    The high concentration of chloride ions, which form a stable coordinate ion with metal ions, such as [AUCL4]-

    is performed in the direction of dissolving. Gold and it forms [AUCL4] -The standard electrode potential after the control ion:

    Wang Shui and other similar mixture are used to dissolve certain iron ore, phosphate rock stone, and phosphate rocks in chemical analysis. Slag, nickel chromium alloys, nickel and selenium, and sulfide of mercury, arsenic, cobalt and lead that is not easily dissolved.

    . As for the specific price
    I don’t know where your city is
    So I can’t tell you the accurate price
