Red organic pigments

This is posted on behalf of Livia Marini and Fiammetta Jahier

    Hallo, we are Fiammetta and Livia, two Italian students attending
    "Istituto Centrale per il Restauro" of Rome
    <URL:http://www.beniculturali.it/icr/>.

    We're engaged in research about red organic pigments used in
    painting and dyeing, from antiquity to the XVII century. We're
    reading the ancient Manuscripts and treatises, looking for
    recipes of red lakes, because we would produce some old
    pigments, for testing their decay. We've met with many
    difficulties looking for the raw materials, like
    Cochineals(coccus cacti), Kermes (coccus ilicis), brasil wood...

    We'll be thankful to all yours if you give us some information
    about these materials, about their decay  and also (and
    especially) about your restauration experiences on red lakes.
    Thank you very much,
