The process of applying 18k gold plating to jewellery involves several steps, including the following: Cleaning: Before plating, the jewellery must be cleaned thoroughly to remove any dirt, oil, or other impurities that may affect the plating process. Preparing the Base Metal: Silver is polished and prepared for plating by applying a layer of a special solution to create a smooth surface. Applying the Gold Plating: Once the base metal is prepared, the gold plating solution is applied to the surface of the jewellery using an electroplating process. The jewellery is submerged in the solution, and an electrical current is applied, causing the gold to be deposited onto the surface of the jewellery. The length of time the jewellery is left in the solution and the strength of the electrical current used determine the thickness and quality of the gold plating. Finishing: After the gold plating is applied, the jewellery is rinsed, dried, and polished to give it a smooth and lustrous finish.
