Lead (Galena) Facts - rocksandminerals.com
Galena is lead sulfide with a hardness of 2.5 on the Mohs scale – actually quite soft – but it is VERY heavy with a specific gravity of 7.4 to 7.6. To put that in perspective, it weighs about 700 pounds per cubic foot! Although lead is by far the most reclaimed industrial metal in the world, demand for it continues to outstrip the supply.

Kohl (cosmetics) - Wikipedia
A group of researchers in China tried to find some scientific basis of this claimed property of lead sulphide (galena) relating to absorption of sun rays when applied into the eyes in the form of kohl. The authors reported the ultraviolet (UV) absorption spectra of a thin film of lead sulphide prepared on "Indium Tin Oxide" (ITO) substrate.
