Surface-decorated articles by noble metals not damaged by electromagnetic waves, method for producing same and liquid gold for insulating over glaze decoration

摘要

A surface-decorated article by noble metal having a decorating matter of noble metal fused to the surface of a ceramic article. The decorating matter has a dual layer structure of a frit layer and an insulating noble metal film layer, which film layer comprising golden components of 60-90 % Au, 3-15 % Si, 2-11 % In and 2-14 % Ca. The noble metal decorating matter is not damaged on exposure to an electronic range, superior in chemical stability and abrasion resistance.
