Keum-boo
''Keum-boo'' (also ''Geumbu'', ''Kum-Boo'' or ''Kum-bu''— Korean "attached gold") is an ancient Korean gilding technique used to apply thin sheets of gold to silver, to make silver-gilt. Traditionally, this technique is accomplished by first depleting a surface of sterling silver to bring up a thin layer of fine silver. Then 24 carat gold foil is applied with heat and pressure— mechanical gilding—to produce a permanent diffusion bond. Pure precious metals such as gold and silver have a very similar atomic structure and therefore have a good potential for bonding. Heating these metals to a temperature between 260–370°C increases the movement of the atoms. When pressure is added, this causes an electron exchange at the surface between the two metals, creating a permanent diffusion bond. This diffusion bond occurs far below the soldering temperature for either metal (Dhein, 2004). Examples of this technique have probably been observed, but not positively identified on pi ...

Depletion Gilding
Depletion gilding is a method for producing a layer of nearly pure gold on an object made of gold alloy by removing the other metals from its surface. It is sometimes referred to as a "surface enrichment" process. Process Most gilding methods are additive: they deposit gold that was not there before onto the surface of an object. By contrast, depletion gilding is a subtractive process whereby material is removed to increase the purity of gold that is already present on an object's surface. In depletion gilding, other metals are etched away from the surface of an object composed of a gold alloy by the use of acids or salts, often in combination with heat. Since no gold is added, only an object made of an alloy that already contains gold can be depletion gilded. Depletion gilding relies on the fact that gold is highly resistant to oxidation or corrosion by most common chemicals, whereas many other metals are not. Depletion gilding is most often used to treat alloys of gold with coppe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Parcel-gilt (partial gilt) objects are only gilded over part of their surfaces. This may mean that all of the inside, and none of the outside, of a chalice or similar vessel is gilded, or that patterns or images are made up by using a combination of gilt and ungilted areas. Gilding gives an object a gold appearance at a fraction of the cost of creating a solid gold object. In addition, a solid gold piece would often be too sof ...

Silver-gilt
Silver-gilt or gilded/gilt silver, sometimes known in American English by the French term vermeil, is silver (either pure or sterling) which has been gilded with gold. Most large objects made in goldsmithing that appear to be gold are actually silver-gilt; for example most sporting trophies (including medals such as the gold medals awarded in all Olympic Games after 1912) and many crown jewels are silver-gilt objects. Apart from the raw materials being much less expensive to acquire than solid gold of any karat, large silver-gilt objects are also noticeably lighter if lifted, as well as more durable (gold is much heavier than even lead and is easily scratched and bent). For objects that have intricate detail like monstrances, gilding greatly reduces the need for cleaning and polishing, and so reduces the risk of damage. Ungilded silver would suffer oxidation and need frequent polishing; gold does not oxidize at all. The "gold" threads used in embroidered goldwork are normall ...

Creativity Techniques
Creativity techniques are methods that encourage creative actions, whether in the arts or sciences. They focus on a variety of aspects of creativity, including techniques for idea generation and divergent thinking, methods of re-framing problems, changes in the affective environment and so on. They can be used as part of problem solving, artistic expression, or therapy. Some techniques require groups of two or more people while other techniques can be accomplished alone. These methods include word games, written exercises and different types of improvisation, or algorithms for approaching problems. Aleatory techniques exploiting randomness are also common. Aleatory techniques Aleatoricism is the incorporation of chance (random elements) into the process of creation, especially the creation of art or media. Aleatoricism is commonly found in music, art, and literature, particularly in poetry. In film, Andy Voda made a movie in 1979 called '' Chance Chants'', which he produced by ...

List Of Most Expensive Paintings
This is a list of the highest known prices paid for paintings. The current record price is approximately United States dollar, US$450.3 million (which includes Commission (remuneration), commission), paid for Leonardo da Vinci's Salvator Mundi (Leonardo), ''Salvator Mundi'' (). The painting was sold in November 2017, through the auction house Christie's in New York. Background The most famous paintings, especially old master works done before 1803, are generally owned or held at museums, for viewing by patrons. Since the museums rarely sell them, they are considered priceless. ''Guinness World Records'' lists Leonardo da Vinci's ''Mona Lisa'' as having the highest ever insurance value for a painting. On permanent display at the Louvre in Paris, the ''Mona Lisa'' was assessed at US$100 million on December 14, 1962. Taking inflation into account, the 1962 value would be around US$ million in .
