Gold leaf is a thin foil of nearly pure gold often used in aesthetic applications. A foil is a very thin sheet of metal, usually made by hammering or rolling a piece of metal. ...

Because gold is highly malleable, it can be worked into sheets just micrometres in thickness without breaking or tearing. Gold leaf is used for the decorative technique called gilding, and has been used for thousands of years in a variety of cultures. Malleability is a physical property of matter, signifying its capability of deformation, especially by hammering or rolling. ... A micrometre (American spelling: micrometer), symbol µm, is an SI unit of length. ... Gilding is the art of spreading gold, either by mechanical or by chemical means, over the surface of a body for the purpose of ornament. ...

Gold leaf can be applied to nearly any non-porous surface. The usual technique involves applying a thin layer of gesso or an adhesive to the surface to be decorated. This adhesive can be applied in any desired pattern, if the entire surface is not to be covered. The sheets of gold are then lifted by static electricity using soft brushes. The gold is so thin that any moving air or excess static electricity can cause unsatifactory results. The decorator then gently lowers the leaf onto the surface, where it is held in place by the adhesive. The goal is to apply the thinnest layer needed, as mistakes with gold are often costly. Gesso is a glue-like paint, most often white, used a base or undercoat when preparing a canvas for painting. ... Static electricity or electrostatics is a field of science and a class of phenomena involving the imbalanced charge present on an object, typically referring to charge with voltage of sufficient magnitude to produce visible attraction, repulsion, and sparks. ...

The sheets often wrinkle when placed, generally the desired appearance. The surface of the gold leaf after application will have many different facets and creases, giving a diffuse luminance rather than a smooth, reflective surface. Facets is a self-published album by American singer/songwriter Jim Croce, released in 1966. ...

Depending on the application, other decorations may be added to enhance the gold. In automotive and motorcycle work, pin striping is painted on where the leafed and non-leafed areas meet. In other decorating, borders of any kind, often wood or paint, are used. Some small items are completely covered in gold leaf. Pin striping describes the application of a pin stripe. ...

The leafed areas can also be worked by brushes of different textures after being applied. This give the surface a pattern, and is a common finishing technique.

Gold leaf has also recently become available pre-glued to a vinyl or paper backing, which can be cut to any desired shape and installed like a sticker.
