The ceramic lustres are organic compounds of precious and base metals offered in the form of finished paint which is applied over-glaze on glass, porcelain, ceramic or glazed pottery. They are liquid and sometimes should be diluted with appropriate diluent (thinner). The ceramic luster should be applied with a soft brush on a thoroughly cleaned already glazed product. Try to make a thin layer. If necessary, use Toluene for cleaning. Get unlimited glaze recipes for gold luster ceramics.

Ceramic lustre, also known as metallic lustre or simply lustre, is a type of decorative finish applied to ceramic surfaces. It creates a lustrous, iridescent effect that adds depth, shimmer, and a metallic appearance to the ceramic piece. Here's some information about ceramic lustre:
Composition: Ceramic lustres are made of metallic compounds suspended in a liquid medium, typically a mixture of metal oxides, salts, and sometimes glass or enamel. Common metallic compounds used in lustre include gold, silver, platinum, copper, and iridescent metal oxides like titanium or bismuth.
Application: Lustre is applied to the ceramic surface after the initial firing and glazing of the piece. It is usually brushed, sprayed, or airbrushed onto the surface in a thin, even layer. The lustre is then fired at a relatively low temperature, called a lustre firing, which allows the metallic compounds to bond with the glaze or ceramic surface.
Firing Technique: Lustre firing is a special firing process that requires precise control of temperature and atmosphere. It is typically done in a low-oxygen or reducing atmosphere, such as a saggar (a protective container) or a specially designed kiln with controlled gas flows. The firing process enables the metallic compounds to undergo a chemical transformation, resulting in the formation of a thin metallic film or nanoparticles on the surface of the ceramic.
Iridescence and Effects: Ceramic lustres create a range of effects, including a metallic sheen, iridescence, and a play of colors. The appearance can vary depending on the type of metallic compounds used and the firing conditions. Lustres can produce gold, silver, or copper-like finishes, as well as vibrant iridescent colors that change when viewed from different angles.
Historical Significance: Lustre techniques have been employed for centuries, dating back to ancient civilizations such as the Egyptians and Persians. It gained prominence during the Islamic Golden Age and continued to be used in subsequent periods. Lustre ceramics are renowned for their exquisite craftsmanship and luxurious appearance, often found in fine art objects, pottery, and decorative items.
Ceramic lustre requires specialized knowledge and skill to achieve consistent and desired results. Due to the use of metallic compounds, safety precautions should be taken when handling lustres, as some compounds may be toxic or pose health risks if mishandled.
