Galvanic Plating is a process that uses electric currents applied to two opposite poles (negative & positive) in a tank of solution which contains the dissolved material of the coating. The product is attached to the negative pole and powered with a negative charge, while the metal dissolved in the solution is powered with a positive charge. The product then attracts the positive-charged metal in the solution, and thus, creating a thin coating of the desired material.
Brushed is a process of using quartz sand to polish a chosen metal (gold, stainless steel, etc.) under high pressure. This finish is an effective method for removing surface imperfections. In addition, it gives a pattern of fine lines parallel to the brushing direction that creates a distinctive look for jewelry.
