Thorium
Thorium is a metal which is very difficult to prepare in a state of purity. Small beads of it have been obtained resembling platinum, and the metal has also been made in the form of a black powder. The metal is resistant to acids, dissolving only in aqua regia (a mixture of nitric and hydrochloric acids). This has been obtained in the form of foil by ramming the powder thorium into copper tubes, beating them flat, and then dissolving away the copper with dilute nitric acid.
Next to uranium, thorium is the heaviest metal known. it is radio-active, although to a much less extent than radium. Thorium alloys with most metals. Its salts are used in the manufacture of gas mantles. At high temperature thorium metal burns in air with the production of a brilliant illumination.
