Products description

1) Tarnish protection - When chains tarnish, one speaks in metal processing industries about the change in the metal surface. This is caused by the deposition of a thin layer of foreign material on the respective metal. The metal usually changes its color to a dark shade, which can be caused by various environmental influences, such as temperatures, light or chemical compounds. The type of tarnishing itself varies between the different types of metal. Silver tarnishes due to the influence of sulfur, which is in the air. An oxide layer is created. This oxide layer also forms on steel, but due to the very high temperatures to which the jewelry material is exposed. During the tarnishing process, steel loses its metallic luster and changes color to slightly red, yellow or blue shades. The metals zinc and lead also tarnish when exposed to particularly high levels of humidity. This is countered by the precious metal gold. Gold does not tarnish and retains its stylish shine in the long term if the proportion of fine gold is sufficiently high. However, the higher the metal content of a gold alloy, the more likely it is tarnishing, as metals also react within alloys. With this fusion of gold and a metal, such as copper or silver, gold can also change its metal surface.
Our tarnish protection offers long-lasting protection against oxidation and discoloration of silver surfaces and low-carat gold alloys. The anti-tarnish layer is completely invisible and has no changes in terms of gloss or color. The start-up protection behavior is improved by applying voltage. It is used in decorative and technical applications.

2) Rhodium plating - Rhodium plating is the further processing of metals and precious metals through a thin layer of rhodium. During this process, known as electroplating, the surface is coated. Here, metal ions are deposited, which adhere to the object to be coated via an electrolytic bath and harden there. This gives a piece of jewelry its resistant corrosion protection. The main advantages of using rhodium lie in the chemical properties of the precious metal. This has a high degree of hardness, but also good formability and toughness, which means that it can be mechanically processed without any problems. This makes rhodium a popular means in the further refinement of pieces of jewelry. The abrasion-resistant tarnish protection creates a smooth and more scratch-resistant surface than is the case with non-rhodium-plated silver. Constant cleaning and polishing is no longer necessary. The latter in particular should be avoided, as the use of a polishing cloth can damage the rhodium layer. Visually, rhodium-plated jewelry is characterized by a slightly grayish sheen compared to light silver jewelry made of silver.

3) Gold plating - Gold plating can fulfill several aspects at the same time. On the one hand, this allows the corrosion-resistant properties of gold to be transferred to other materials and, on the other hand, the visual attractiveness of gold is used. When gilding objects are coated with a thin layer of gold. To manufacture the respective item entirely from gold would be too expensive due to the rarity of gold, which is why it makes sense to coat it with a fine layer of gold. Gold plating can be applied to a wide variety of materials; metals such as zinc, stainless steel, brass, bronze, silver or copper are particularly suitable. But textiles, paper, wood, plastic or ceramics can also be refined with this process. Pure gold can be used for gilding, but gold alloys are more common, e.g. 333 or 585 gold. These alloys with silver, copper, cadmium, zinc or nickel components give the gold more hardness, make it more resistant and also ensure a wide range of colors for the precious metal coating. So gold plating in red gold, yellow gold and white gold is possible, even blue tones and green colors of the precious metal are conceivable. The gilding can be done mechanically with flattened gold sheet or chemically using electroplating technology.
