K gold
K is the abbreviation of the English word Karat, which is a symbol used internationally to indicate the purity of gold (that is, the gold content). K-gold is an alloy whose main component is gold. It is made by adding a certain proportion of other metals (such as copper, silver, zinc, nickel, etc.), and different gold contents can be matched according to demand.
Gold-covered: The domestic standard QB/T 1131-2005 "Regulations on the Thickness of Gold Covering Layers for Jewelry" defines "gold-covering covering layers" as follows: "Gold coverings obtained by firmly wrapping gold foil on the base of jewelry products by mechanical processing methods layer, called the gold cladding layer", while requiring "the thickness of the gold cladding layer is not less than 0.5μm (micron)".
Tip: The gold overlay thickness here is defined in terms of pure gold.
Gold wrapping is a method of wrapping gold or K gold foil on the surface of a silver or other metal carcass by mechanical rolling or high temperature welding. The inner material is not precious metals such as gold and platinum, but some alloy materials such as aluminum, copper, and zinc (there are also silver-coated gold). Material is wrapped. Gold-clad jewelry has the luster and texture of gold jewelry, as well as high wear resistance and antioxidant capacity.
gold plated
Gold-plated, the English name is Gold-Plated. The domestic standard QB/T 1131-2005 "Regulations on the Thickness of Gold Covering Layers for Jewelry" defines "gold-plated covering layers" as follows: "A gold covering layer obtained by processing methods such as electroplating or chemical plating is called a gold-plated covering layer", and at the same time It is required that the "gold cover layer thickness is not less than 0.5μm (micrometer)". It should be noted that the gold-plated overlay with a thickness of 0.05μm-0.5μm is defined as "thin-layer gold-plated overlay" in the national standard.
Brass Gold Plated Jewelry
Gold plating is to use electroplating or chemical plating to coat a layer of gold on the base metal, but the coating is generally relatively thin. Gold plating is divided into two categories: one is gold plating of homogeneous materials, and the surface of gold jewelry is plated with gold to improve the brightness and color of the jewelry; the other is gold plating of heterogeneous materials: the surface of non-gold materials is plated with gold. Gold plating (such as silver copper gold plating), improves the color of the material, thereby improving the viewing effect of the item.

The difference between gold-clad and gold-plated
01
Different processing methods
Gold-cladding adopts mechanical processing methods, and gold-plating adopts processing methods such as electroplating or chemical plating.
02
The purity of the overlay varies
In the domestic standard, the gold content of the gold-clad coating shall not be less than 375‰, and the gold content of the gold-plated coating shall not be less than 585‰.
03
Covering layers (alloys) vary in thickness
In domestic standards, the gold-clad and gold-plated overlays require the same thickness of pure gold, which is no less than 0.5 μm. However, the common coatings on the market are generally not pure gold. To meet the above-mentioned requirements of "the gold content of the gold-clad coating is not less than 375‰, and the gold content of the gold-plated coating is not less than 585‰", it is necessary to Satisfy that the thickness of pure gold is not less than 0.5μm, so the common gold-clad cover layer (alloy) on the market is thicker than the gold-plated cover layer (alloy).
Gold sticking: Gold sticking is a craft with a long history. "Tian Gong Kai Wu" records high praise for the gold sticking process: "As for gold, it is beautiful and precious in the world, so it is artificially made into foil and then applied." Gold requires gold foil as a raw material, and has the characteristics of being thin as cicada wings, soft as satin, and light as a feather. Gold foil can be pasted into a lubricating appearance, and can also be processed into exquisite pictures. In ancient times, the carved beams and other internal structures of many imperial palaces and temples were often gilded, making the buildings extremely brilliant.
Gold sticking, in simple terms, is to make high-quality gold into gold foil as thin as cicada wings, and then paste the gold foil on various objects. Before the modern gold-clad technology was born, gilding and cladding had the same meaning, that is, a very thin gold foil was attached to the surface of the utensils for protection. Thanks to the modern gold cladding process, the gilding process has become a unique process. Gold paste has high application value for some products that cannot be processed by gold plating and gold coating technology.
Gilt: Gilt is an ancient traditional craft, which is to evenly coat a layer of thick paste of gold and mercury on jewelry with low value such as copper and silver, and then bake it at low temperature. Evaporated, and the gold adhered to the copper surface, which was then flattened and polished. Currently, this method is rarely used.
Gold jewelry has been popular since ancient times, and it also plays a pivotal role in my country's jewelry market. Distinguish the terms related to gold jewelry, and choose a gold jewelry that you like.
