Many collectors are chasing after gold for its dazzling gloss.\nHowever, it is technically impossible to achieve 100% purification of gold.\nEven pure gold with a maximum purity of 999.0\u2030 will have\n“impurities”. This also makes a small part of pure gold appear\n“rust spots”, which brings wearer trouble. In fact, as long as more\nattention is paid to some maintenance details, the occurrence of “rust\nspots” can be largely avoided.<\/p>\n\n\n\n
To avoid “rust spots”, we must know the cause of\n“rust spots”. The impurities in pure gold personalized necklaces cheap<\/strong> are mainly water-insoluble inorganics,\norganics, and water-soluble inorganic salts. These impurities cause pure gold\nto “rust” due to factors such as the environment, climate, and\nimproper human operation. Collectors can try to choose some large precious\nmetal manufacturers with endorsements of brands and technical capabilities.\nEven if they produce “rust spots”, they can get more friendly\nsolution.<\/p>\n\n\n\n Understanding the cause of “rust spots”, we can take care\nof this and maintain gold from a scientific perspective. This can be roughly\ndivided into two categories of protection and conservation, which can be\nsummarized as “avoid and necessary”:<\/p>\n\n\n\n \u201cAvoid\u201d is mainly about good collecting habits and protecting your\n“gold” (gold coins, medals, gold bars, etc.):<\/p>\n\n\n\n 1. Avoid direct\ncontacting with “gold”, especially gold and silver commemorative\ncoins. Once the transparent plastic bag that comes with the factory is opened,\nthe coin surface will be in contact with the air. At the same time, the sweat\nin your hand contains moisture, which may cause oxidation of solid gold name necklace <\/strong>gold products.\nWhen touching, wear thin gloves as much as possible, and use your thumb and\nindex finger to pinch the edges of the product to prevent sweat stains from\ncontaminating the surface of the collection.<\/p>\n\n\n\n 2. Avoid gold\nproducts come into contact with saliva. Especially when appreciating the\ncollection, don’t talk to the collection to avoid splashing droplets that cause\nchemical changes on the surface of gold and silver bars and medals.<\/p>\n\n\n\n 33. Avoid placing\ngold products in a special climate and environment, but keep them in a\nventilated, dry, and moisture-proof place, and the ambient temperature should\nnot be too high.<\/p>\n\n\n\n In addition to the three avoidances in preservation, as collectors,\nyou can also create a relatively healthy collection environment for gold\nproducts customizable best friend\nnecklaces <\/strong>through simple “necessary”:<\/p>\n\n\n\n One is that it is necessary to put a natural camphor block in the\nplace where gold is placed: to prevent mold from breeding on the box of gold\nand silver coins and prevent the box from getting worms. Because mold plaques\nand insect bodies are acidic, metabolite such as liquid or gas is acidic or\nalkaline, it is easy to cause oxidation reaction on the surface of gold\nproducts best friend rings<\/strong>.<\/p>\n\n\n\n The second is that it is necessary to place the color-changing\nsilica gel at the four corners of the gold and silver coin storage place: the\nwater absorption rate of the silica gel is about 25%, and the color-changing\nsilica gel has extremely strong moisture absorption. When dry, the\ncolor-changing silica gel is blue and turns red after absorbing moisture. The\nweight is about 3 kilograms per cubic meter in the northern region and 5\nkilograms of color-changing silica gel in the southern region, which can ensure\na month of dryness. When all the color-changing silica gel becomes red, it will\nlose the function of absorbing water and moisture. At this time, it can be\nplaced in an oven and dried at 80 \u00b0 C for 3 hours, wait until the water vapor\nhas risen to disappear and the silica gel has all turned blue. Then put it back\ninto the gold and silver coin storage place to keep the gold bracelet for your girlfriend<\/strong> and silver\ncoin surface dry.<\/p>\n\n\n\n Whether it is “avoid” or “necessary”, it is a\nreference experience formed by many collectors in the course of many years of\nconservation. From a scientific point of view, it is to try to prevent impurities\nin gold products from chemical reactions such as oxidation with other\nsubstances, so as to protect the quality of investment collections. Similarly,\nit is also because of the consideration of preventing chemical reactions. At\npresent, the requirements of temperature and humidity in the safes of most\nbanks cannot meet the conditions of gold product collection. Especially for\nconsumers who are new to the gold custom\nfriendship necklace <\/strong>collection, try to avoid putting gold directly in the\nbank for preservation.<\/p>\n\n\n\n The value of gold lies in its own natural attributes on the one\nhand, and on the other hand from human recognition. Perhaps from a certain\nperspective, this recognition should also include the conservation of gold\nproducts. There is no doubt that \u201cavoid and necessary\u201d mentioned below can help\nyour gold investment collection achieve greater value.<\/p>\n","protected":false},"excerpt":{"rendered":" Many collectors are chasing after gold for its dazzling gloss.
