Anotations

Scope note:

A mineral composed of lead tetroxide that has the same composition as red lead, an orange-red pigment used since ancient times. Minium deposits have been found in Egypt, however, most sources indicate that Egyptian red lead pigment was manufactured from lead metal and litharge rather than ground from minium.
