CHARISMA Expert Meeting on Natural Organic Colorants

The CHARISMA project will organize next year two workshops devoted to natural organic colorants.
Prior to these workshops an expert meeting was organized at the Netherlands Institute for Cultural Heritage (ICN). The expert meeting was dedicated both on dyeing and pigment preparation from natural organic colorants. The main goals of this meeting were; one to serve as a pilot for the workshops to be held next year in Munich and Brussels, two to share knowledge with the European partners working with these subjects and three to create new reference materials, that can be used as study objects.
