Minium

Description

A mineral composed of Lead tetroxide that has the same composition as Red lead, an orange-red pigment. Minium deposits have been found in Egypt, however, most sources indicate that red lead pigment was manufactured from lead metal and litharge rather than ground from minium. Even so, the mineral name minium has been used to refer to the red lead pigment. From Pliny's time to the 17th century, the name minium was also used to refer to Vermilion and Cinnabar.
