5 thoughts on “Is it pure gold?”

  1. Foot gold is not pure gold, but it is real gold. Foot gold is currently the closest to pure gold in all gold products. Foot gold generally refers to gold with more than 99%of gold. It is the most purity gold in the market.
    The general gold content of jewelry content of more than 99.9%is called thousands of gold, and gold with a gold content of more than 99.99%is called thousands of gold. But today's jewelry processing technology cannot be purified to 99.99%at all. The so -called pure gold is 100%pure gold. However, pure gold only exists in theory, and the current technology cannot be achieved, because the hardness of the jewelry with high gold content will become lower, the texture will become soft, and the jewelry will be easily deformed.
    and from May 4, 2016, my country's national standard has canceled the standards of thousands of feet (99.9%of pure gold) or even 10,000 -foot gold (99.99%of pure gold), and the definition of foot gold (99.0%) to Pure gold, from this perspective, can be defined as pure gold, but the gold content is not 100%.
    The gold is a kind of high -colored gold. The appearance of this gold is red and yellow. Its texture is very soft. You can use your nails to marked on the surface. Obvious fish scales appear. Foot gold is one of the main raw materials for making gold jewelry. According to the regulations of my country, precious metals such as gold and silver need to be on the surface, and the jewelry produced by the gold generally includes "gold 990", "G990", and "AU990".

  2. No, the gold-the gold content is not less than 990 ‰
    Gold cleaning method
    1. The luster of protecting the gold jewelry can be applied to a layer of nail polish thinly on it.
    2. If there are black silver films on the surface, 2 grams of salt, 7 grams of soda, 8 grams of bleaching powder, 60 ml of clear water, are made into a "golden device cleaning agent", put the gold jewelry in a bowl, and the golden jewelry is in a bowl. Pour in the cleaning agent. After 2 hours, remove the golden jewelry, rinse with water (preferably not hard water), buried in the wood chips to dry, and then wipe it with a soft cloth.
    3, the ring inlaid with a cotton roll with a popsicle or match stick, wet the gemstone and its frame in the mixed fluid of the dew and glycerin, and then use the velvet cloth to brighten the ring. Do not scrape it with a kind of sharp objects.
    4, salt and vinegar mixed synthetic cleaning agent, using it to wipe the pure gold jewelry, which can make a long time.
    5, wipe or scrub with hot rice soup with hot rice, can also restore gloss.
    6, scrubbing with ammonia water

  3. Foot gold is not pure gold. The gold content of foot gold is more than 90%, while pure gold refers to gold with gold content of more than 99.9%. Foot gold is a kind of high -colored gold. Its appearance is red and yellow, with the characteristics of soft texture and strong ductility. After several bending of this golden gold, there will be obvious fish scales. Foot gold is not pure gold, and the gold is gold with more than 90%of gold. Pure gold theoretically refers to the gold content of 100%of gold, but due to the gold purifying process, it is generally referred to as pure gold with gold content of more than 99.9%. Foot gold is a kind of high -colored gold. The appearance of this gold is red yellow. Its texture is very soft, and it can be traced on the surface with nails. And after several bending of the foot gold, obvious fish scales will appear on the bending part.
    Femin is used to make one of the main raw materials for gold jewelry. my country stipulates that precious metals such as gold and silver need to marked ingredients and color on the surface. G990 "" "AU990" and other imprints.

  4. Starting on May 4, 2016, my country's national standards abolished the standards of thousands of feet (99.9%of pure gold) or even 10,000 -foot gold (99.99%of pure gold), and the definition of foot gold (99.0%) as the definition of pure gold was changed. From this point of view, Foot gold is pure gold, but not the content of gold or 100%. Let ’s follow the editor to learn about some of the knowledge of gold!

    1. The ingredients and calculation methods of gold
    The gold is a yellow precious metal (chemical symbol AU) with high density, soft, and corrosion. Its ductility is the highest among known metals. Calculating the goldenness is based on karat (abbreviated as K), and is divided into 24 levels (that is, 1K ~ 24K) according to the gold ratio, so 1K is equal to 4.1666%of the gold content in terms of purity. Generally speaking, none of the jewelry materials used in countries around the world will not be lower than 8K, which means that the commonly use K gold components are 17 types (ie 8K ~ 24K gold). In addition, the definition of 24K gold in the world has always been controversial. This is because naturally cannot have a real 100%pure gold, so when defining the purity of "pure gold", there may be different standards in various countries. Therefore Pay attention to related marks when purchasing precious metals.

    The hardness of pure gold is similar to the nails, so gold jewelry is easier to deform than other precious metal accessories. Gold Master needs to synthesize pure gold and other metals to form alloy to increase its hardness in order to make more jewelry changes. Generally speaking, gold will join silver, copper, zinc and other metals Jewelry is inlaid or large accessories, and the metal made in this way is "K gold", which is common in the mainstream of 18K gold (75.0%gold content) and 14k gold (58.5%gold content). Others are relatively rare.
    . Generally speaking, Asians love higher purity such as 22K and 18K gold, and Europeans and Americans love 14K or 10K gold jewelry. However, in recent years, Asians have gradually begun to accept 14K gold jewelry. In terms of production, the proportion of 14K gold users is the same as 18K gold because young people accept 14K gold more. Although the lower the price, the lower the price, but the 14K gold is more suitable for creating complex jewelry due to increased hardness, more durable and at the same time.

    2. The interesting relationship between gold and color
    When K gold meets the content standards, in order to enrich the changes of K gold, you can synthesize the color richness by adjusting the proportion of other alloys The changeable K gold, this is where K gold is welcomed. The famous Japanese jewelry magazine "Gem Four Seasons" mentioned that there are 450 kinds of K gold, but the most commonly used is about 20 kinds. Today I will introduce you to the more mainstream yellow, red, and white K gold recipes.
    yellow k gold: It is a yellow precious metal alloy, which is made of gold, silver and brass. The different proportion of silver and brass adjusts the depth of yellow color; red K gold: It is a pink precious metal alloy, which is made of gold and silver and red copper. Red copper is the main cause of K gold red. Red K gold is also known as rose gold. Rose gold is bright and high than pure gold and strong ductility. It is used for jewelry manufacturing and is also called powder gold, red gold and purple gold. Because of its wide use in Russia in the early 19th century, it was also known as Russia or Zijin of Russia. White K gold: For white precious metal alloys, it is made from gold and silver. Because white K gold is white, it is the white metal that is the easiest to confuse with platinum (platinum), but it is completely different from platinum. Moreover, because white K gold's main material is still gold, you must know that "the color of white K gold will still be yellow", which must not be compared with platinum and silver. And why the white K gold jewelry sold in the workshop is white, which is actually the reason why it has been re -plated. If the white K gold jewelry you bought feels yellow a few years later, this is a normal phenomenon. After the electroplating layer becomes thinner, the real white K gold is exposed. Consider and pay attention.
