What colour is Minium?
Minium is a pigment with a strong orange-red colour, more orange than its name suggests. It stands out for its brightness and density, making it useful for covering surfaces completely. The shade can shift depending on how long it is heated and the size of its particles. Minium is often confused with other red pigments like cinnabar and vermilion, but it is distinct for being made from lead and for its tendency to darken over time.
Where does Minium come from?
The name minium comes from the river Minius, now called Miño or Minho, on the border between Spain and Portugal, near ancient cinnabar mines. In Roman times, the word referred to both red lead and ground cinnabar, which led to confusion. Minium made from lead was cheaper and easier to produce than cinnabar, so it became the most used bright red pigment in medieval Europe. It was known in China as early as 300 BC and described in Chinese texts by the 5th century.
How is Minium made?
Minium is produced by heating white lead pigment in air. As it is roasted, the white lead first turns yellow, then becomes orange as it changes into lead tetroxide. The final colour depends on how long it is heated and the conditions during roasting. The pigment is a fine powder with high density, giving it strong covering power in oil paints.
Where Minium is used
This pigment was a favourite for decorating medieval manuscripts, especially for drawing capitals, headings, and small illustrations called miniatures. It was also used in Persian and Indian miniature paintings, and in Japanese Ukiyo-e paintings, where it has often stayed bright because the scrolls were kept rolled up. Minium was applied as a cosmetic in ancient cultures and used for inscriptions on gold and marble. In modern times, it has been used in protective paints for metal surfaces, especially in Russia, Norway, India, and China.

Minium is sometimes mistaken for cinnabar or vermilion, which are also red pigments but made from mercury rather than lead. Its colour can range from orange to red depending on how it is prepared. In some cases, it can darken to brown or black, especially in watercolour or on walls, due to chemical changes.
