Methods

You can keep the product at home with a chemical or galvanic way. Each of them has its own characteristics.

Galvanic

The coating is applied with gold 925 samples. Gilding allows you to make a product more valuable. The main method of coating is the use of sodium, essential solution and contact with zinc. One galvanic method is the most effective.

It is this method that is better suitable for processing jewelry.

To create a gold coating silver descends into aqueous solution of salts. Then exposure to electric shock. In this case, gold acts as an anode, and silver – cathode.

Consider an exemplary process of galvanic gilding.

  1. Pour the electrolyte into a small container.
  2. Dissolve gold in liquid.
  3. Put a silver decoration in the container and leave for a while. In the process through the liquid, electric current should pass.
  4. On the product will begin to settle oxis. Layer is very thin.
  5. Get decoration and leave to complete drying.
  6. Polish or cover with a special protective layer.

    The layer is really very thin, but it is distinguished by strength, durability. It is worth noting that the gold coating can be made thicker, there are no restrictions. Usually, the jeweler stipulates this moment with the client.

    For gilding, this method uses certain alloys.

    1. Clean gold yellow. There are no additives in the alloy, a metal of 999 samples is used.
    2. Yellow Gold with a small amount of cobalt. The sample is still the same, 999. Additive is needed exclusively for strength, does not affect the appearance.
    3. Red gold is also called Russian. You can also make Pink, Italian. The latter has a little more yellow. Shades range from copper-red to pale pink.
    4. Green Gold. Used alloy with the addition of silver or nickel.
    5. White gold. The process is used.

    The final cost of the product depends on how the alloy is made by the gild.

    It is worth noting that the first two options are the most expensive, but there are nuances. The abrasion of gloss is very distinguished by the finished product of silver from the same of gold.

      The golden middle will be Italian or Russian alloy.

      Chemical

      The process involves applying gold chloride on a silver product. Initially, gold rolled into foil, and then crushed. The particles are then falling into the composition of salt and nitric acid. It is also called royal vodka.

      You can don at home, following step-by-step instructions.

      1. Make a solution of 30 g of salt and 10 g of high concentration nitric acid. On 1 g of gold, 10 ml of liquid will be required.
      2. Dissolution needs to be produced in porcelain tanks. The process takes from a pair of hours to 2-3 days.
      3. After complete dissolution to evaporate the composition on a water bath at a temperature of 70-80 ° C. Resulting in a viscous liquid. Gold should be stirred in the process of evaporation glass stick.
      4. Silver object degrease 10-20% sodium or boil in soda solution. Rinse in a 25 percent solution of hydrochloric acid. Then rinse the decoration with water.
      5. Immerse the product. After some time, the subject will cover the gilder.
      6. Get out of the tank, wash the decoration. Wipe and polish wool cloth.

        Additionally, it is worth noting that there are different ways to prepare a mixture for gilding with a chemical method. Yes, and gold can be used in different samples. The process is longer than when using electroplating gilding. When working with acids, adhere to all safety rules. It is important to carry out gilding in a ventilated room and using remedies.

        How long is the gilding?

        Silver product after the procedure is covered with a thin film. It is decorative and pretty sensitive to the external environment. Adverse factors include the following:

        • Aggressive chemicals+
        • incorrect care+
        • Excessive friction about human skin, contact with then.

        With daily use it is worth paying a lot of attention to the care of the product. Excessive humidity leads to silver oxidation.

        In fairness it is worth noting that corrosion appears on additional metals alloy, on copper and nickel. These components and begin to darken, be covered by a raid, and not silver itself.

        Before cleaning or washing it is worth removing the ring with gilding. Interaction with aggressive and any other household chemicals accelerates the oxidation process. Before washing and hike in the shower, it is also worth removing all the gold-plated items. Strengthened friction felt the layer of gold before its full abrasion.

        3. Products need to be cleaned, but only the right way.
        4. You can not store jewelry in the bathroom or in the kitchen. High humidity will lead to loss of attractive shine.

        Gold plated silver requires adequate care. If the usual ring can be cleaned with a soft toothbrush, then in this case the film will be completely corrupted.

          Major assistants when cleaning decorations with gilding:

          • Suede rag+
          • ethanol+
          • vinegar.

          Suede is designed for polishing. It can be used immediately after cleaning. Also, the suede cloth will come in handy if the decoration is worn every day. Should polish it in the evenings before removing in the box.

          You can not immerse the gold-plated product in soda or soap solution. This will lead to a decorative layer. It is allowed to apply alcohol onto a cotton disk and wipe the decoration. If pollution is significant, you can omit the product into acetic solution for 20 minutes or less.

            Give gilding shine and alcohol. You can also put the product in beer for 15 minutes for the same purpose. Regular cleaning of silver with gilding can be made using light acetic solution and lounge tissue. It is enough to moisten a rag and gently wipe the decoration. It is not necessary to actively clean, how to press.
