Tin is the 49th most abundant element in Earth's crust, representing 2 ppm compared with 75 ppm for zinc, 50 ppm for copper, and 14 ppm for lead. [56] Tin does not occur as the native element but must be extracted from various ores. Cassiterite (SnO
Evidence of direct tin trade between Europe and the Eastern Mediterranean has been demonstrated through the analysis of tin ingots dated to the 13th-12th centuries BC from sites in Israel, Turkey and modern-day Greece; tin ingots from Israel, for example, have been found to share chemical composition with tin from Cornwall and Devon (Great ...
Tin medal affected by tin pest. Tin pest is an autocatalytic, allotropic transformation of the element tin, which causes deterioration of tin objects at low temperatures. Tin pest has also been called tin disease, [1] tin blight, tin plague, [2] or tin leprosy. [3] It is an autocatalytic process, accelerating once it begins.
While there was plenty of the expected elements on the shards (four of which were glass and one of which was ceramic)—including nickel, copper, zin, tin, antimony, gold, mercury, and lead ...
[10] [11] It was recognised as an element by Louis Guyton de Morveau, Antoine Lavoisier, Claude Berthollet, and Antoine-François de Fourcroy in 1787. [6] It is believed that lead smelting began at least 9,000 years ago, and the oldest known artifact of lead is a statuette found at the temple of Osiris on the site of Abydos dated around 3800 BC ...
Tin foil was once a common wrapping material for foods and drugs; replaced in the early 20th century by the use of aluminium foil, which is now commonly referred to as tin foil, hence one use of the slang term "tinnie" or "tinny" for a small aluminium open boat, a small pipe for use of a drug such as cannabis, or for a can of beer. Today, the ...

A study showed that 99.5% of the controlled food cans contain tin in an amount below that level. [4] However, un-lacquered tin cans with food of a low pH, such as fruits and pickled vegetables, can contain elevated concentrations of tin. [2] The toxic effects of tin compounds are based on its interference with iron and copper metabolism.
