Brief description: when freshly exposed to air, thallium exhibits a metallic lustre, but soon develops a bluish-grey tinge, resembling lead in appearance. A heavy oxide builds up on thallium if left in air, and in the presence of water the hydroxide is formed.

The Element Thallium - Basic Physical and Historical Information ... There are no uses for metallic thallium since pure thallium quickly combines with oxygen and water vapor from the atmosphere, forming a black, powdery substance. Thallium, used in conjunction with sulfur or selenium and arsenic, forms low melting glass.

There are only a few areas with a naturally very high thallium concentration. Thallium is produced industrially only in small quantities (the worldwide industrial consumption in 1991 was 10-15 tonnes/year). Thallium and its compounds have a wide variety of industrial uses.

(Gr. thallos, a green shoot or twig) Thallium was discovered spectroscopically in 1861 by Crookes. The element was named after the beautiful green spectral line, which identified the element. The metal was isolated both by Crookes and Lamy in 1862 about the same time.
