Fire-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 soft or ...

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 normal ...

Gilt-bronze
Ormolu (; from French ''or moulu'', "ground/pounded gold") is the gilding technique of applying finely ground, high-carat gold– mercury amalgam to an object of bronze, and for objects finished in this way. The mercury is driven off in a kiln leaving behind a gold coating. The French refer to this technique as "''bronze doré''"; in English, it is known as "gilt bronze". Around 1830, legislation in France had outlawed the use of mercury for health reasons, though use continued to the 1900s. Craftsmen principally used ormolu for the decorative mountings of furniture, clocks, lighting devices, and porcelain. Process The manufacture of true ormolu employs a process known as mercury-gilding or fire-gilding, in which a solution of mercuric nitrate is applied to a piece of copper, brass, or bronze; followed by the application of an amalgam of gold and mercury. The item is then exposed to extreme heat until the mercury vaporizes and the gold remains, adhering to the metal o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daoism
Taoism (, ) or Daoism () refers to either a school of philosophical thought (道家; ''daojia'') or to a religion (道教; ''daojiao''), both of which share ideas and concepts of Chinese origin and emphasize living in harmony with the '' Tao'' (, 'Thoroughfare'); the ''Tao'' is generally defined as the source of everything and the ultimate principle underlying reality. The ''Tao Te Ching'', a book containing teachings attributed to Laozi (), together with the later writings of Zhuangzi, are both widely considered the keystone works of Taoism. Taoism teaches about the various disciplines for achieving perfection through self-cultivation. This can be done through the use of Taoist techniques and by becoming one with the unplanned rhythms of the all, called "the way" or "Tao". Taoist ethics vary depending on the particular school, but in general tend to emphasize ''wu wei'' (action without intention), naturalness, simplicity, spontaneity and the Three Treasures: , compassion, ...

Carthage
Carthage was the capital city of Ancient Carthage, on the eastern side of the Lake of Tunis in what is now Tunisia. Carthage was one of the most important trading hubs of the Ancient Mediterranean and one of the most affluent cities of the classical world. The city developed from a Canaanite Phoenician colony into the capital of a Punic empire which dominated large parts of the Southwest Mediterranean during the first millennium BC. The legendary Queen Alyssa or Dido, originally from Tyre, is regarded as the founder of the city, though her historicity has been questioned. According to accounts by Timaeus of Tauromenium, she purchased from a local tribe the amount of land that could be covered by an oxhide. As Carthage prospered at home, the polity sent colonists abroad as well as magistrates to rule the colonies. The ancient city was destroyed in the nearly-three year siege of Carthage by the Roman Republic during the Third Punic War in 146 BC and then re-developed as R ...

Lucius Mummius
Lucius Mummius (2nd century BC), was a Roman statesman and general. He was consul in the year 146 BC along with Scipio Aemilianus. Mummius was the first of his family to rise to the rank of consul thereby making him a novus homo. He received the agnomen Achaicus for his victories over the Achaean League destroying the famous ancient city of Corinth, at that time a leading city of the League, as part of his campaign. Mummius' victory over the Achaean League and the sack of Corinth placed Rome firmly in control of all Greece from a political standpoint - something Rome had avoided doing even though their involvement in the Greek East dated back as far as 226 BC when they confronted Illyrian piracy. Career Almost nothing is known about Lucius Mummius' early career. He won one of the praetorships (for 154 BC) during the elections of 155 BC. Hispania In 154 BC the Senate assigned Mummius the task of restoring order in Hispania Ulterior (Further Spain), which was reeling from a rev ...

Capitoline Hill
The Capitolium or Capitoline Hill ( ; it, Campidoglio ; la, Mons Capitolinus ), between the Forum and the Campus Martius, is one of the Seven Hills of Rome. The hill was earlier known as ''Mons Saturnius'', dedicated to the god Saturn. The word ''Capitolium'' first meant the temple of Jupiter Optimus Maximus later built here, and afterwards it was used for the whole hill (and even other temples of Jupiter on other hills), thus ''Mons Capitolinus'' (the adjective noun of ''Capitolium''). In an etymological myth, ancient sources connect the name to ''caput'' ("head", "summit") and the tale was that, when laying the foundations for the temple, the head of a man was found, some sources even saying it was the head of some ''Tolus'' or ''Olus''. The ''Capitolium'' was regarded by the Romans as indestructible, and was adopted as a symbol of eternity. By the 16th century, ''Capitolinus'' had become ''Capitolino'' in Italian, and ''Capitolium'' ''Campidoglio''. The Capitoline Hi ...

Mercury (element)
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver and was formerly named hydrargyrum ( ) from the Greek words, ''hydor'' (water) and ''argyros'' (silver). A heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar ( mercuric sulfide). The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide. Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely p ...

Picture Frame
A picture frame is a protective and decorative edging for a picture, such as a painting or photograph. It makes displaying the work safer and easier and both sets the picture apart from its surroundings and aesthetically integrates it with them. Construction A picture frame is a container that borders the perimeter of a picture, and is used for the protection, display, and visual appreciation of objects and imagery such as photographs, canvas paintings, drawings and prints, posters, mirrors, shadow box memorabilia, and textiles. Traditionally picture frames have been made of wood, and it remains very popular because wood frames can provide strength, be shaped in a broad range of profiles, and allow a variety of surface treatments. Other materials include metals, e.g. silver, bronze, aluminum, and stiff plastics such as polystyrene. A frame surface may be of any color or texture. Both genuine gilding and imitation gold remain popular, although many other surfaces are to be found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronze
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as strength, ductility, or machinability. The archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age starting from about 1300 BCE and reaching most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.

Vitruvius
Vitruvius (; c. 80–70 BC – after c. 15 BC) was a Roman architect and engineer during the 1st century BC, known for his multi-volume work entitled '' De architectura''. He originated the idea that all buildings should have three attributes: , , and ("strength", "utility", and "beauty"). These principles were later widely adopted in Roman architecture. His discussion of perfect proportion in architecture and the human body led to the famous Renaissance drawing of the '' Vitruvian Man'' by Leonardo da Vinci. Little is known about Vitruvius' life, but by his own descriptionDe Arch. Book 1, preface. section 2. he served as an artilleryman, the third class of arms in the Roman military offices. He probably served as a senior officer of artillery in charge of ''doctores ballistarum'' (artillery experts) and ''libratores'' who actually operated the machines. As an army engineer he specialized in the construction of ''ballista'' and '' scorpio'' artillery war machines for si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
