Description
Liquid native mercury in a bottle stamped “Minas de Almaden y Arrayanes, S.A.”.
Mineral from the Almaden mining district in Spain.
Mercury is one of the few native metals to exist in a liquid state at room temperature.
The Almaden mining district has been in operation for over 2,000 years and has probably produced 1/3 of the mercury mined in the world today.
