In order to achieve a "shiny result", the surface condition of the object, as well as a knowledge of the base material, is of major importance especially for decorative coatings. All precious metal baths are shine-maintaining but not shine-forming. A possibly inconspicuous scratch in a high-gloss surface is not smoothed out but is intensified by finishing. Creative surface effects however, such as matt effects produced by brushing or sand jets are retained.

With materials of organic origin and gemstones, which are frequently processed in connection with decorative utensils or jewellery, it should be noted that these can be destroyed or corroded by acidic or basic electrolytes.

Where may and can the object be affixed to the goods carrier? Small parts are fixed using copper wire and a special threading technique on the plating rack.
The parts must be securely fixed so that they are not lost or damaged in the production process. Eyes, holes and inner threads are especially suitable as contact zones - current flow between goods carrier and workpiece.
Faraday's law - the basic principle of electrolysis .

The bath sequence is obtained from the desired layer structure.

Production sequence using silver plating:  Ultrasound cleaning, degreasing, rinsing, pickling, rinsing, pre-silver  plating,  main silver, sparing rinsing, fresh rinsing, drying

At porous soldered joints between hollow bodies there is the risk of penetration from the degreasing bath and then the electrolyte. The sensitive high-performance electrolyte can be destroyed. Liquid generally diffuses through these pores a long time after the plating and becomes noticeable as a result of unsightly spot formation (sweating)
