The extraction of lead is easy and relative cheap when compared to most metals. Below are 6 facts you may have not known about lead.

1. Lead Characteristics

Lead is extracted from galena or lead sulfide, again very easy to extract. The melting point of lead is 621.4 degrees F. The melting point for STEEL is 2500-2800 and pure iron 1535 degrees C. Melting lead is as easy as starting a fire and throwing the lead in the hot ashes. In comparison to other metals, lead has a significantly lower melting point. Making lead easy to manipulate.

2. The use of lead since prehistory

Researchers believe lead was used in the late 4000 BC days, tracing lead ores in the mountains of Turkey. The oldest artifact was discovered in Israel in 2012.

3. Lead is Poisonous to the Human Body
