Pb stands for Lead and Lead (II) Oxide can be written as PbO in its shortened form. Some people also refer to this as monoxide. There was a time when this was used together with glycerine sets in order to create the hard bottoms of the aquariums that may be seen in restaurants and even in various houses.
