TY - CONF A1 - Rabin, Ira T1 - Studies of the black writing inks N2 - In recent years, the interest in the composition of the inks in papyri documents grew exponentially. Different types of inks were found in the period 4th century BCE to 7th century CE. The paper will demonstrate a simple protocol based on comparison of the ink transparency in the near infrared light and X-ray fluorescence spectroscopy. The importance of including ink composition into new catalogues and possible formats of such data will be also presented and discussed.
