Gilding is a decorative technique that involves applying a thin layer of gold or a gold-like substance to a surface. This process can enhance the appearance of various materials, including wood, metal, and paper. Gilding is often used in art, architecture, and furniture to create a luxurious and eye-catching effect. There are several methods of gilding, such as water gilding, oil gilding, and transfer gilding. Each method has its own unique application process and finish. Gilding has been used for centuries, dating back to ancient civilizations, and continues to be popular in modern design and restoration projects.
