Rock/Mineral - Galena in Quartz

Description

This listing is for 1 mineral. SOLD INDIVIDUALLY. Galena is a metallic silvery color mineral composed of the elements of lead and sulphur, PbS. Galena is formed by hydrochemical reactions and is found in beds and veins in eruptive rocks such as quartz. Galena is the main ore of lead, which is widely used for making car batteries, ammunition, weights for lifting, weight belts for diving, leaded crystal glass, and protection from radiation. Galena can contain up to 20 % silver and is often mined for its silver content rather than the less valuable lead content. Galena may tarnish and become dull when exposed to the air for a long period of time. The tarnish can be removed by scrubbing with soapy water. WARNING: The lead content of galena is toxic and carcinogenic. Do not ingest galena or breathe galena dust. Not for children under the ages of 14. Origin: Morocco
