| posted by Suzie Chhouk Learn about the history of the word 'miniature'. 'Miniature' was derived from the Latin word, minium which means 'red lead'--or more specifically, lead(II,IV) oxide. |
The molecular formula of 'red lead' is Pb3O4.
A unit cell (on left) of the lead(II,IV) oxide crystal is tetragonal; lead(II,IV) is shown in grey and oxygen is shown in red. Part of the tetragonal crystal structure is shown on the right.
