What does minium mean?
Minium is a historic red pigment made from lead compounds, particularly lead tetroxide. It was valued for the vivid, warm red color it produced and was used by painters, manuscript illuminators, ceramic workers, and craftspeople. In modern discussion, the term often appears in art conservation and historical pigment analysis, where its composition and presence can help identify how an object was made. Although once widely used, minium fell out of favor as safer synthetic pigments became available and because lead-based materials are toxic. The word is also connected etymologically with miniature: the Latin word minium referred to a red pigment traditionally used in making very small paintings, and the development of “miniature” reflects that historical association. Today, minium is mainly encountered in specialized historical and technical contexts.

Where does minium come from?
The English word minium comes from Latin minium, the ancient name for red lead or a red lead-based pigment. The same Latin term was associated with the art of painting very small objects, and through French it contributed to the word miniature. Later English forms such as miniate and miniation developed from the idea of decorating or coloring something with minium.
