Lead is a soft, malleable poor metal. It is also counted as one of the heavy metals. Metallic lead has a bluish-white color after being freshly cut, but it soon tarnishes to a dull grayish color when exposed to air. Lead has a shiny chrome-silver luster when it is melted into a liquid. Melting point is 327.46 °C, which can be easily achieved on a cooking stove.
Melted lead accumulates a lot of energy as heat, so it is very dangerous (a lot more dangerous than boiling water) since it can cause serious burns.
