Metallic lead beads dating back to 6400 BC have been found in Çatalhöyük in modern-day Turkey.

The Romans also used lead in molten form to secure iron pins that held together large limestone blocks in certain monumental buildings.

In alchemy, lead was thought to be the oldest metal and was associated with the planet Saturn. From the Latin word plumbum 99 1952 Workers at Argonne, Los Alamos, USA, and the University of California at Berkeley, USA. USA Named after "Albert Einstein"

Lead and its compounds are poisonous
Pencil leads in wooden pencils have never been made from lead
Large quantities of lead, both as the metal and as the dioxide, are used in storage batteries.

Lead is used as electrodes in the process of electrolysis.

It is added to brass to reduce machine tool wear.

Lead, in either pure form or alloyed with tin, or antimony is the traditional material for bullets and shot in firearms use.
