Silver

Silver is a chemical element; it has symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

In Greek mythology, Theia (; ) also called Thea, Thia, Euryphaessa, Aethra or Basileia, was one of the Titans, the children of Uranus (Sky) and Gaia (Earth).

Bimetallism, also known as the bimetallic standard, is a monetary standard in which the value of the monetary unit is defined as equivalent to certain quantities of two metals, creating a fixed rate of exchange between them. In all known historical cases, the metals are gold and silver.

Argyria or argyrosis is a condition caused by excessive exposure to chemical compounds of the element silver, or silver dust. The most dramatic symptom of argyria is that the skin turns blue or blue-gray, and is usually most prominent in sun-exposed areas of the skin. It may take the form of generalized argyria or local argyria. Generalized argyria affects large areas over much of the visible surface of the body. Local argyria shows in limited regions of the body, such as patches of skin, parts of the mucous membrane, or the conjunctiva.

It is added as a powder or paste, then fired until it melts or at least softens, and flows or is pushed into engraved lines in the metal. It hardens and blackens when cool, and the niello on the flat surface is

In a more general sense, the term hallmark is used to refer to any standard of quality. Not to be confused with responsibility marks that are the marks of the maker.

Vark (also varak, Waraq, or warq) is a fine filigree foil sheet of pure metal, typically silver but sometimes gold, used to decorate Indian sweets and food. The silver and gold are edible, though flavorless. Vark is made by pounding silver into sheets less than one micrometre (μm) thick, typically 0.2–0.8 μm. The silver sheets are typically packed between layers of paper for support; this paper is peeled away before use. It is fragile and breaks into smaller pieces if handled with direct skin contact. Leaf that is 0.2 μm thick tends to stick to skin if handled directly.
