Gilding techniques involve applying a thin layer of gold or gold-like material to a surface, enhancing its appearance and value. Common methods include gold leaf, where delicate sheets of gold are adhered to surfaces using an adhesive, and gold paint, which provides a more durable finish. These techniques are often used in art, architecture, and decorative objects. Historically, gilding has been employed in various cultures, from ancient Egyptian artifacts to Renaissance paintings. The process can also include water gilding, which requires a polished surface for a reflective finish, and oil gilding, which is more forgiving and suitable for outdoor applications.
