  1. An indigo-based pigment... from an overlooked recipe in a 13th century Arabic text. Fascinating experiments & scholarship from Joumana - & highlighting the digitised manuscript treasures in our libraries!

  2. Thortveitite is the main ore of scandium.

    Titanite is prized for its beauty, comes in different colours & is a source of titanium and hence titanium dioxide, used as a white pigment since ~1910. So, it gets my art vote.

    Gets physics vote for trichroism- transparent specimens can show 3 colours depending on viewing angle. #MinCup25 #scicomm #artHist #pigment

  3. Both wavellite and dioptase are sometimes made into jewelry but (though a rare pigment) dioptase has been on artwork used since Neolithic times so it wins my art vote!

    See for instance Neolithic sculpture from Jordan, some ancients Asian murals & Russian religious icons.

  4. Kyanite is used in porcelain(more dishware and plumbing than art) but it is used in jewelry. Plus it is an index mineral. But I am going to give the art vote to Dioptase for its unparalleled history as a pigment which stretches back to the Neolithic! For the #MinCup24 semi-finals and the last surviving pigment in competition!
