Something about silvering process
Firstly, before cutlery is silvered, it´s necessary to get rid of all
grease and small dirt adhesed on the surface of cutlery. In SOLA, we are
paying extra attention to pre-treatment, especially for the sake of eliminating
any possible deficiencies that may result from inconsistent processing.
Therefore, among all available and used degreasing methods, such as degreasing
in organic solvents, or degreasing in alkaline aqueous solutions, we use the
most precise method, namely electrolytic degreasing. Electrolytic degreasing
meets the highest requirements on the surface cleanliness of cutlery.
This process not only accelerates and improves degreasing, but also removes
the last miniature dirt and grease from the surface of cutlery, that could
remain on the surface by using other methods. The principle of electrolytic
decreasing is based on the use of direct electric current. When the current
passes, the electrolytic substance is discharged, removing the adhesive forces
(by which is the dirt bound to the surface) by the action of the gases formed on
the electrodes and are reliably tearing off the dirt from the treated
The remaining process is simple. After electrolytic cleaning, the cutlery is
flushed several times until it finally receives first silver platinum in the
pre-bath and then in the silvering bath itself. After re-rinsing with warm
water and thorough drying, the silvered cutlery remains only to be polished with
the polishing aid and cutlery is ready for use.
