Maria Geba, Ana-Maria Vlad, Goina Veronica Manea, Nicoleta Vornicu, Cristina Bibere: Medieval manuscripts in the Romanian Cultural Heritage: Research and preservation.

The museums, libraries and religious institutions of Romania contain a valuable patrimony of documents and old books, many of them written in different kinds of ink and some exhibiting polychrome ornamentation.

The studies performed on the medieval manuscripts aimed at a noninvasive analysis of writing and decoration materials. The research was based on optical microscopy and non destructive X-ray fluorescence.

A great majority of these books and documents needed an extensive restoration and conservation treatment, performed in the Research and Restoration - Conservation Centre from "Moldova" National Complex of Museums of Iasi, in order to return them to their original state.

The results of this study will add greatly to the present-day knowledge about techniques and materials for writing and decoration of medieval manuscripts from Romanian collections.
