Prepare the mold, mix the imported gypsum powder with water, use the instrument to extract air, increase the density, pour the mixed gypsum into the mold to avoid air in the gypsum, and then take measures. Remove the yellow belt, heat it at high temperature, prepare the gold, melt the gold into a liquid, pour the gold liquid into the Gold Smelter Furnace, remove it after a while, put it in water to cool, and clean the semi-finished product with a high-pressure water gun. Then use the Jewelry Wax Injector to heat the wax mold and quartz crucible to 850 ~ 1200 ° C, and pour the molten gold into the mold, showing single-piece ingredients suitable for processing gold jewelry, such as rings and bracelets. Cut all the arm and bracelet arms apart and make them separately because all the arm and bracelet arms are the places with the most stress and the most wear. After casting, the density of gold is not enough. We need advanced technicians to change the density of gold through manual forging to make it more durable and durable. Advanced hammering and filing technology make gold jewelry more delicate and smooth. Then check the interior of the decoration, sand all dead corners with sandpaper, and further polish with fine tools such as needles, wheels, flat wheels. During the forging and grinding process, a large amount of gold cannot be recovered, which also increases the cost. In the gold production, due to the large loss, it is usually impossible to fine-grind tools such as surface grinding, needles, wheels, and wheels. It is very difficult to recover gold. Only 2g-10g can be recovered. Hydrochloric acid immersion is dangerous for craftsmen. After polishing, dip in dilute hydrochloric acid. After soaking in hydrochloric acid, soak the crude parabola in water and carefully polish it by hand. After repeated grinding, the color should be blasted, and pure water is used to clean the acid solution on the jewelry. The purpose of the color explosion is to remove all metals on the gold surface, such as trace metals such as iron and zinc, so as to permanently maintain the reddish color of gold and not fade in the future. Pure water is used in the forging process to avoid trace metals containing tap water from penetrating into the gold. After the color is fried, it is cleaned and polished by hand again. Attentions in daily cleaning of the jewelry.

Pearl jewelry is best washed with a special cleaning solution or mild detergent and soaked for a few minutes. Some difficult to clean areas can be gently brushed with a soft bristle brush, then rinse with water, and finally dry with a soft cotton cloth or silk. Remember, you must use a gentle motion when using a brush, otherwise it may leave scratches on the metal, or even damage the setting, affecting the safety of the gem.
General jewelry stores have free cleaning services. Sending it to a jewelry store for professional cleaning is a wise choice. Jewelry shops often use professional Digital Ultrasonic Cleaner Jewelry to clean their jewelry. As long as your gems have no visible cracks, you can safely use this method. If there are cracks, it is best to avoid using ultrasonic cleaners, because vibration during cleaning will increase cracks and cause serious consequences. In addition, some dense micro-mosaic styles are not recommended for ultrasonic cleaning to avoid stone dropping during the cleaning process.
