A process of ceramic coatings on silver or silver-plated articles is developed in order to prevent surface tarnish, which is employed as ornaments on bags, garments or accessories such as necklaces, earrings, etc. The process comprises the steps of: forming a beryllium film on the surface of the article by fixing a stainless steel plate to an anode, fixing the silver or silver-plated article to a cathode and plating the surface of the silver or silver-plated article with beryllium in an electrolyte containing beryllium sulfate (BeSO4.4H2O) by an electroplating method; buffing the article coated with the beryllium film; washing and drying the buffed article using a surfactant; forming the resultant ceramic coating by dipping the dried article in ceramic coating solution which includes 20 to 80 cc of glass water No. 1 (liquid sodium silicate), 5 to 60 g of sodium metasilicate, 5 to 30 g of sodium tungstate, 5 to 10 g of molybdic acid in 1 liter of water; and drying the wetted article.
