Gold leaf

Gold leaf is gold that has been hammered into thin sheets (usually around 0.1 μm thick) by a process known as goldbeating, for use in gilding. Gold leaf is a type of metal leaf, but the term is rarely used when referring to gold leaf. The term metal leaf is normally used for thin sheets of metal of any color that do not contain any real gold. Gold leaf is available in a wide variety of karats and shades. The most commonly used gold is 22-karat yellow gold. Pure gold is 24 karat. Real, yellow gold leaf is approximately 91.7% pure (i.e. 22-karat) gold. Traditional water gilding is the most difficult and highly regarded form of gold leafing. It has remained virtually unchanged for hundreds of years and is still done by hand. 5,000 years ago, Egyptian artisans recognized the extraordinary durability and malleability of gold and became the first goldbeaters and gilders. They pounded gold using a round stone to create the thinnest leaf possible. Except for the introduction of a cast-iron hammer and a few other innovations, the tools and techniques have remained virtually unchanged for thousands of years. Gold-leaf forging is a traditional handicraft in Nanjing (China), produced as early as the Three Kingdoms (220 – 280 AD) and Two Jins (266 – 420) dynasties; it was used in Buddha-statue manufacturing and construction. It was widely used in the gilding of Buddha statues and idols and in the construction industry during the Eastern Wu (222-280) and Eastern Jin (266–420) dynasties. During the Qing dynasty (1640-1912), the technology developed, and Nanjing gold leaf was sold overseas. It retains traditional smelting, hand-beating and other techniques, and the gold leaf is pure, uniform and soft. On May 20, 2006, it was included in the first batch of national intangible cultural heritage representative items. Modern gold-leaf artists combine ancient traditional crafts with modern technology to make traditional gold leaf. Forging skills are more sophisticated. Gold-foil production in Nanjing follows the ancient production process.

Painting
Painting is the practice of applying paint, pigment, color or other medium to a solid surface (called the "matrix" or "support"). The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, can be used. In art, the term "painting" describes both the act and the result of the action (the final work is called "a painting").
Gilding
Gilding is a decorative technique for applying a very thin coating of gold over solid surfaces such as metal (most common), wood, porcelain, or stone. A gilded object is also described as "gilt". Where metal is gilded, the metal below was traditionally silver in the West, to make silver-gilt (or vermeil) objects, but gilt-bronze is commonly used in China, and also called ormolu if it is Western. Methods of gilding include hand application and gluing, typically of gold leaf, chemical gilding, and electroplating, the last also called gold plating.
Roman art
The art of Ancient Rome, and the territories of its Republic and later Empire, includes architecture, painting, sculpture and mosaic work. Luxury objects in metal-work, gem engraving, ivory carvings, and glass are sometimes considered to be minor forms of Roman art, although they were not considered as such at the time. Sculpture was perhaps considered as the highest form of art by Romans, but figure painting was also highly regarded.
