Oil gilding is a decorative technique that involves applying thin layers of gold leaf or metal leaf to a surface using an oil-based adhesive. This method allows for a rich, luminous finish that enhances the appearance of various objects, such as frames, sculptures, and furniture. The process begins with preparing the surface and applying a layer of oil size, which remains tacky for a period. Once the size is ready, the gold leaf is carefully laid onto the surface, adhering to the oil. Afterward, the gilded area can be burnished or left matte, depending on the desired effect.
