The reasons for 18K gold discoloration are as follows: 18k gold is a gold content of at least 75%of the gold content, that is, alloys with 18/24 in gold, and the remaining 25%are other precious metals, including platinum, nickel, silver, etc. Through contact with cosmetics, skin care products or hand -toilets with chemical ingredients, the plating layer of 18K gold will be corroded and damaged, so we show the phenomenon of discoloration and fading we see.
In addition to chemicals such as cosmetics, it will affect the appearance of 18K gold, and the sweat on the human body will also change 18K gold. 99%of human sweats are water, and about 1%are waste and harmful substances in the human body, such as: chloride, lactic acid, ammonia, etc. After contacting the silver and copper in the K gold jewelry, chemical reactions will also produce silver chloride and copper sulfide, and show dark black chemical salt. This of these chemical salt is the main reason for changing K gold color. It can be found that when this chemical salt contacts the human skin through 18K gold jewelry, it will also leave the wearer's skin to leave black stains ~ 18k how to remedy after changing color? The 18K gold after discoloration and discoloration has lost its former luster, no longer exquisite eye -catching, and the value is also a grade. But it does not mean that the TA is not here ~ It can be remedied according to the discoloration. If it is due to a lot of dust on it, the gloss is reduced, then it can be cleaned by 18K gold emerald jewelry, and gently wipe it with soft hair gently with soft hair. , Especially at the gap, be careful when cleaning to prevent the emerald from falling. But if it is caused by the corrosion of the chemicals, it is necessary to polish and polish the 18K gold surface coating part, and then re -plated. This is a technical job, and it is recommended to send it to a professional jewelry institution for treatment. The cost of gold plating is very low. Although the 铑 itself is very expensive, the coating only requires a small amount of crickets. Usually, the cost of plating in the processing layer is low, so there is no need to worry about the cost of cost. After re -plating, 18K gold can restore the beautiful and bright luster of the past. On how to maintain 18K gold emerald? 1. Avoid contact with chemicals 18k gold. The primary color of gold is golden yellow. The color of 18 gold we often see is the color after electroplating. However, if 18K gold and the substances of chemical ingredients (such as: skin care products, hand washing solution, vinegar, etc.) are contacted, the plating layer will be corroded and expose the primary color of 18K gold. Therefore, when we use cosmetics, we can first remove the 18K gold emerald jewelry. Do not wear cooking, wash, or chemical experiments. 2. Avoid collision or friction with hard objects such as metal. although 18K gold has a certain hardness, it will also leave scratches when crashing with precious metals such as platinum, or it will be squeezed and deformed, becoming unsightly. Therefore, when wearing 18K gold emerald jewelry, it is not advisable to do severe physical or sports. 3. Avoid long -term heat or cold environment The metal has the properties of thermal expansion and contraction. Therefore, 18K gold will be affected by temperature. Putting 18K gold in a cold or overheated environment will affect the firmness of 18K gold inlaid, and may even cause 18K gold to loosen off, causing unnecessary losses. Therefore, try to avoid wearing 18K gold emerald jewelry to go in and out of hot and cold temperature differences, such as cold storage and bathrooms. 4. Avoid cleaning with hand -toilet with chemical ingredients When cleaning 18K gold emeralds, do not use the hand -toiler with chemical ingredients to avoid corroding valuable metals. web links
