Paint pigment - although we are trying to do away with that as its rather toxic.

No, lead oxide and lead monoxide are not the same. Lead oxide typically refers to a combination of lead with oxygen in various oxidation states, such as PbO, PbO2, or Pb3O4. Lead monoxide specifically refers to the compound PbO, where lead is in a +2 oxidation state. Lead monoxide is also known as litharge or lead(II) oxide.
The formula for lead monoxide is PbO
The chemical formula for lead monoxide is PbO. It is composed of one lead (Pb) atom and one oxygen (O) atom.
Lead monoxide has an ionic bond. Lead, being a metal, tends to lose electrons to form a cation, while oxygen, being a non-metal, tends to gain electrons to form an anion. This electrostatic attraction between the cation (lead) and the anion (oxygen) results in an ionic bond in lead monoxide.
Monoxide is 6' 2".
Carbon monoxide is a toxic gas; an intoxication can lead to death.
