Artists employ meticulous techniques to ensure the longevity of gold or metallic accents on porcelain sculptures. The process begins with selecting high-quality materials, such as pure gold leaf or lustrous metallic oxides, which are resistant to tarnishing. Before application, the porcelain surface is carefully prepared to enhance adhesion, often through precise glazing or sanding.

Firing plays a crucial role—gold leaf is typically applied after the initial glaze firing and then fired again at lower temperatures (around 700–800°C) to bond the metal without compromising its sheen. For metallic oxides, artists may use overglaze techniques, sealing the accents with a protective clear glaze to prevent wear.

Additionally, proper handling and display are essential. Avoiding direct sunlight, humidity, and abrasive cleaning preserves the metallic luster for decades. Some artists even incorporate modern sealants or resin coatings for added durability. By combining traditional craftsmanship with innovative methods, these delicate details remain radiant for generations.
