In South America, especially among the Andes; the mines of Mexico, and those of Nevada, also, are rich in this metal. The richest and most important silver mines in Europe are those of Königsberg, in Norway, and of Andalusia, in Spain. With the exception of gold, silver is the most ductile of all metals: a single grain may be extended into a plate 126 inches long, and half an inch broad. It is capable of still further extension, but its tenacity is inferior even to that of iron or copper. A silver wire one-tenth of an inch thick will scarcely bear a weight of 290 pounds, whilst a gold wire of the same thickness will support nearly double that weight. Like some other metals, it is unalterable by air or moisture, but by an intense heat may be volatilized, being sometimes found in the soot of chimneys where large quantities are melted.
Volatilized, made to fly off by evaporation.
In what state is Silver usually found?
It is rarely found in a state of purity, being generally mixed with other metals, as gold, lead, &c. Masses of native silver are of no determinate form; being found sometimes in small branches, sometimes in threads, or very frequently in leaves, as in the Siberian mines. Native, or pure silver is chiefly found in the mines of Potosi. Silver was used as money in commerce 1100 years before the foundation of Rome.
Commerce, trade of one nation with another, or different persons, &c. with each other.
What is Tin?
A white metal, softer than any other excepting lead, more elastic, and more sonorous. Though tin is the lightest of all metals, its ore is, when rich, the heaviest of all metallic ores. It has both smell and taste; is less ductile than some harder metals, though it may be beaten into very thin leaves; and it fuses so quickly, that it requires a heat much less than is sufficient to make it red-hot.
Was not the use of Tin very early known?
Tin was found in Britain from the earliest ages; the Phenicians traded to Cornwall for this metal 600 years before Christ.
