What is gilding and gilding. History of the art of gilding - a hot way from antiquity<\/h2>\n\n\n\n
Gilding is a subtle gold layer<\/a>The thickness varies from 1 to 25 microns, which is used to coat a variety of surfaces to give an object a resemblance to the precious metal. The thickness varies from 1 to 25 microns. <\/p>\n\n\n\n The technology allows the use of gilding in jewelry design, interior design, architecture, cosmetology and the food industry.<\/p><\/blockquote>\n\n\n\n The art of gilding has been known for many thousands of years. Previously, two methods were used: cold and hot. The cold method was based on attaching gold plates to the surface. The hot method involved the use of fire: gold and mercury were applied to objects. The surface was burned, the mercury evaporated and the gold adhered firmly to the base. Knowledge of the toxic effects and severe poisoning of workers in the workplace forced the method to be abandoned.<\/p>\n\n\n\n The first gilded costume jewelry and household items were discovered back in ancient times. The ancient Egyptians were among the first to cover the sarcophagi of the pharaohs with gilding. Then gilding was mastered by China and ancient Russia. Since then, there have been many techniques on how to coat different objects with gold. <\/p>\n\n\n\n The electroplating technique of gilding has been known since the 19th century and is considered safe for use by jewelers. Electroplating was a new stage of development in the gilding era.<\/p>\n\n\n\n The active study of the properties of gold made it possible to use gilding techniques in painting, icon painting, forging or casting to decorate furniture, and building architecture from the decoration of ancient Egyptian tombs to the pompous Baroque style of Bartolomeo Rastrelli.<\/p><\/blockquote>\n\n\n\n Jewelry gold plating has a number of valuable properties that define its main functions:<\/p>\n\n\n\n - ennoble the appearance of an inexpensive product;<\/strong><\/p>\n\n\n\n - protect surfaces from corrosion and oxidation.<\/strong><\/p>\n\n\n\n Properties in turn depend on the thickness of the layer of gilding, precious metal.<\/p>\n\n\n\n The gilding of the metal is done in different shades, thanks to the addition of impurities. The white color is the result of mixing gold and silver elements. A pink hue is obtained by adding copper. <\/p>\n\n\n\n It is important to remember that the original color of the precious metal depends on the original grade of gold.<\/p><\/blockquote>\n\n\n\n The quality of the gilding depends on the application technique chosen. Different methods of application, special reagents, and professional substances can be used. Often when gilding different surfaces, a layer can be used to help even out the color and increase the hardness of the material.<\/p>\n\n\n\n The longevity of objects largely depends on the thickness of the gold layer. To keep the gilding for longer, a layer of at least 0.1 mm thickness is applied. In this way, it is possible to keep the luster of items for several months with proper care.<\/p>\n\n\n\n Jewelry gold plating is divided into types according to thickness:<\/p>\n\n\n\n Nowadays gold plating is used in many fields:<\/p>\n\n\n\n Jewelers quite often use gold plating for silver objects. Gold plating is also available for bronze, copper, cast iron, brass, aluminum, galvanized iron, and other known metals. Certain industries practice the gilding of wooden, clay, plastic and plaster objects. A gold layer can be given to ceramics and cardboard.<\/p>\n\n\n\n The technique of gilding changed, improved and divided into two main methods of application: clay and on mordant glue.<\/p>\n\n\n\n Other types of gilding based on the above:<\/p>\n\n\n\n Several simple, accessible methods of gilding are actively used. Gold leaf or gilding can be used to cover interior elements, household items, and costume jewelry.<\/p>\n\n\n\n The gold leaf method involves the use of 960-gold leaf. The method is used to cover the domes of temples, icons, sculptures, fountains, clocks and other parts of decoration. Recently, the use of food-grade gold has become popular, for decorating cakes, desserts, candies, and even meat dishes. <\/p>\n\n\n\n For such purposes, a wisp with a plate thickness 10 times thinner than the cross-section of human hair is used. <\/p><\/blockquote>\n\n\n\n Potash is now considered a cheaper alternative to gold plates. Due to the absence of precious metals, a gram of such Covers<\/a> Costs dozens of times less. It is produced in the form of gold foil or strips. It is a copper-aluminum or zinc alloy. <\/p>\n\n\n\n By changing the alloy composition it is possible to imitate gold, silver, bronze material. It is possible to apply a pattern to such surfaces. <\/p>\n\n\n\n Rhodium can protect jewelry from damage.<\/p><\/blockquote>\n\n\n\n The gilding in at home<\/a> provides for several ways:<\/p>\n\n\n\n These methods can be used at home, but will require chemicals, tools and special equipment, which is not available to everyone.<\/p><\/blockquote>\n\n\n\n For gold plating at home, chlorine gold is used, which can be made by by melting the precious metal<\/a> in a \"hellish mixture\" consisting of a 1:3 proportion of nitric and hydrochloric acids.<\/p>\n\n\n\n After placing the metal in the solution, the liquid should be evaporated. It is important that the fire is separated from the container in the process. As a result, a dry mass of chloride gold remains at the bottom.<\/p>\n\n\n\n Important: Vaporize acids very carefully so as not to burn your hands or mucous membranes of the respiratory system.<\/p><\/blockquote>\n\n\n\n Immediately prior to use, the mass is mixed with potassium cyanide and the resulting gold until a mass with the consistency of mush is obtained. The prepared mixture is used to stain objects. When finished, allow the material to dry, rinse the surface, then proceed to polishing.<\/p>\n\n\n\n If you add ether during the gilding process, it will allow you to decorate the applied layer of gold with a pattern, make an inscription or a binding. When finished, wait for the ether to evaporate and give a shine by polishing the surface with a cloth. <\/p>\n\n\n\n To obtain a thick layer, gilding at home is done with zinc contact. To prepare the composition for coating silver<\/a> items will be required:<\/p>\n\n\n\n Gild copper and brass with the following mixture:<\/p>\n\n\n\n Before applying the solution, the surface should be well cleaned of dirt. The object is placed in a preheated gilding mass. The last thing to be added is a zinc stick, which is a binder.<\/p><\/blockquote>\n\n\n\n The electrolytic method of electrolytic gilding provides a strong and high-quality coating. The hue of the coating obtained by this technique will directly depend on the constituents of the gold mass, can range from reddish<\/a> to light yellow. <\/p>\n\n\n\n The technology provides for two types of compositions:<\/p>\n\n\n\n Preparation of mixtures:<\/p>\n\n\n\n Carefully mix together the liquid with sodium phosphate and gold chloride. Lastly add the solution from step 3. The liquid is heated to 62\u00b0 C using a platinum anode.<\/p>\n\n\n\n It is used to cover silver<\/a>, steel, tin, copper, brass, other metals.<\/p>\n\n\n\n The preparation of the electrolysis consists in the sequential preparation:<\/p>\n\n\n\n The product is immersed in the solution for 16 hours, after which it acquires an interesting matte color.<\/p>\n\n\n\n Lacquer, olive oil and pinena in a mixture called gulfarba, which is used to treat the surface. One day after application, gold leaf is applied on top. The solvent-based mixture allows you to give the gold a matte finish. <\/p>\n\n\n\n Gilding has been used for centuries in many different applications. Its most popular use is in modern technology in jewelry and food production.<\/p>\n\n\n\n In their jewelry, gilding is used by famous jewelry brands such as:<\/p>\n\n\n\n Turkish gold offered to tourists is also popular. Turkish craftsmen use alloys of gold, copper and silver. Gilding is used to enhance the appearance. Regardless of the amount of noble metal composition, jewelry is considered jewelry, with a corresponding value.<\/p>\n\n\n\n As far back as the Middle Ages, it became popular to use gold as a food additive; it was attributed medicinal properties. This trend has been revived these days. Gold leaf can be found in pastry shops and restaurants. Desserts, pastries and candies are covered with it. Individual gourmets prefer gilding with seafood and meat. For convenience, the food industry uses gold in sheets, powder, flakes and granules. <\/p>\n\n\n\n Such decoration is considered an important accent of the dish, emphasizing the festive atmosphere.<\/p><\/blockquote>\n\n\n\n Any piece of jewelry, even gilded ones, must be hallmarked. In Russia, it is customary for gilding to indicate the metal that has been gilded, so it is more often stamped 925 Sample<\/a> from silver. Imported gold-plated items are always indicated by the carat index. The carat and letter symbol indicate the method of gold plating. <\/p>\n\n\n\n![\"History](\"https:\/\/drago-met.ru\/wp-content\/uploads\/2021\/04\/zolochenie-i-pozolota-1.png\")
