Medieval inks for heritage conservation
(PHYSorg.com Archaeology & Fossils)

The fact that historical archives, libraries, museums, writing workshops and even monasteries, currently conserve medieval manuscripts is not only a question of heroes or ordinary people who went through the trouble to save them, passing them down from one generation to the next, or who hid them so they would not be destroyed. The materials used to write and draw upon paper were crucial so that surviving written texts can be read, translated and interpreted nowadays.
