08 Hutchinsonite
Thallium is the dark twin of lead. This thick, greasy metal is similar in
atomic mass but even more deadly. Thallium is a rare metal that appears in highly toxic compounds
consisting of rather strange combinations of elements. The effects of thallium exposure are even more
peculiar, and include loss of hair, serious illness
through skin contact and in many cases, death.
Hutchinsonite is a hazardous but dramatic mixture of thallium, lead and
arsenic. The three poisonous metals form a lethal mineral cocktail that should
be handled only with great caution. Hutchinsonite was named after John
Hutchinson, a prominent mineralogist from Cambridge University. The mineral is
found in mountainous regions of Europe, most frequently in ore deposits.
