Silver or metallic gray is a color tone resembling gray that is a representation of the color of polished silver. Silver ingot The visual sensation usually associated with the metal silver is its metallic shine.
Silver sulfide is an inorganic compound with the formula Ag 2 S. A dense black solid, it is the only sulfide of silver. It is useful as a photosensitizer in photography. It constitutes the tarnish that forms over time on silverware and other silver objects. Silver sulfide is insoluble in most solvents, but is degraded by strong acids. Silver ...
Argyria or argyrosis is a condition caused by excessive exposure to chemical compounds of the element silver, or silver dust. [1] 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.
The name derives from Latin argentum, translated as "silver" or "white metal". The word argent had the same meaning in Old French blazon , whence it passed into the English language. In some historical depictions of coats of arms , a kind of silver leaf was applied to those parts of the device that were argent.
Silver chromate is an inorganic compound with formula Ag 2 CrO 4 which appears as distinctively coloured brown-red crystals. The compound is insoluble and its precipitation is indicative of the reaction between soluble chromate and silver precursor salts (commonly potassium/sodium chromate with silver nitrate).
Silver bromide (AgBr), a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light. This property has allowed silver halides to become the basis of modern photographic materials. [ 2 ]
Silver iodide is an inorganic compound with the formula Ag I. The compound is a bright yellow solid, but samples almost always contain impurities of metallic silver that give a grey colouration. The silver contamination arises because some samples of AgI can be highly photosensitive. This property is exploited in silver-based photography.
Archaeopteryx lithographica isolated feather with a black coloration VOA report about the coloration of Psittacosaurus. Dinosaur coloration is generally one of the unknowns in the field of paleontology, as skin pigmentation is nearly always lost during the fossilization process.
