Contrairement aux pigments organiques, leurs principaux composants sont d\u00e9riv\u00e9s de substances inorganiques, ce qui d\u00e9termine leurs propri\u00e9t\u00e9s physiques et chimiques uniques.

Au d\u00e9but, le noir de fum\u00e9e \u00e9tait le principal pigment inorganique, tandis que son \u00e9quivalent, la craie, \u00e9tait \u00e9galement un pigment courant. La terre color\u00e9e \u00e9tait \u00e9galement largement utilis\u00e9e, et l'oxyde de fer naturel \u00e9tait \u00e9galement un pigment inorganique courant.<\/p>\n\n\n\n<p>- Il y a 5 000 ans, nos anc\u00eatres produisaient d\u00e9j\u00e0 r\u00e9guli\u00e8rement du plomb blanc.<\/p>\n\n\n\n<p>- Il y a environ 2 300 ans, mon pays disposait de la technologie n\u00e9cessaire pour raffiner le vermillon. Cependant, d'autres pays ont \u00e9galement obtenu des succ\u00e8s consid\u00e9rables dans la production de pigments.<\/p>\n\n\n\n<p>- Au d\u00e9but du XVIIIe si\u00e8cle, un Allemand du nom de Diesbach a mis au point une m\u00e9thode de production du bleu de Prusse. Environ un si\u00e8cle plus tard, le Fran\u00e7ais Vauquelin a invent\u00e9 une m\u00e9thode pour produire du jaune de chrome et, une vingtaine d'ann\u00e9es plus tard, le Fran\u00e7ais Guimet a produit de l'outremer.<\/p>\n\n\n\n<p>- Le lithopone a \u00e9t\u00e9 mis au point dans les ann\u00e9es 1870. L'apparition ult\u00e9rieure de pigments composites \u00e0 base de titane et de m\u00e9thodes de production de dioxyde de titane a favoris\u00e9 une avanc\u00e9e significative dans la production de pigments inorganiques.<\/p>\n\n\n\n<p>- \u00c0 ce jour, la gamme des pigments inorganiques est pratiquement compl\u00e8te, l'accent \u00e9tant mis sur l'am\u00e9lioration des performances, la r\u00e9duction de l'impact environnemental et le d\u00e9veloppement de pigments fonctionnels sp\u00e9cialis\u00e9s (tels que ceux destin\u00e9s \u00e0 la protection contre la corrosion, \u00e0 la fluorescence et aux propri\u00e9t\u00e9s sensibles \u00e0 la temp\u00e9rature).
