YELLOW - Precious metal Ceramics Luster Lustre for overglaze application

Yellow luster for overglaze application in ceramics is a type of decorative finish that can be applied to the surface of already glazed ceramics to add a shimmering, metallic effect, often with a yellowish hue. Luster decoration involves the application of a thin layer of metallic compounds over the surface of a glazed piece, which is then fired at a relatively low temperature compared to the initial glaze firing. This process causes the metallic compounds to form a thin film on the surface, creating the lustrous, iridescent effect.

The compounds used for yellow luster typically contain metals such as gold, silver, platinum, copper, or their oxides, mixed into a medium that allows for easy application. Gold, for example, can produce a range of colors from red to yellow lusters depending on the specific formulation and firing conditions.

The process of applying luster involves several steps:
Preparation of the ceramic piece: The ceramic item should be already glazed and fired. The surface needs to be clean and free of grease or dust.
Application: The luster is applied to the surface of the piece using a brush or by dipping. It's important to apply it evenly and carefully since the thickness of the application can affect the final appearance.
Firing: After application, the piece is fired in a kiln at a lower temperature than used for glazing, typically between 650°C and 750°C (1112°F to 1472°F), although this can vary based on the specific luster composition. This firing process is what creates the metallic sheen.
Cooling: After firing, the piece must cool down gradually to prevent cracking or crazing.
Lusterware, the term for ceramics decorated with such techniques, has a long history, with early examples dating back to the 9th century in the Middle East. It became popular in various cultures, including in Europe, where it saw a resurgence in interest during the 19th century.
Because of the materials involved, particularly when using metals like gold, luster decoration can be relatively expensive. Additionally, the process requires a degree of skill and experience to achieve consistent and beautiful results. Yellow luster pieces are prized for their beauty and unique qualities, often used in decorative arts and fine ceramics collections.
