Gregory Bearman, Mark S. Anderson & Kenneth Aitchison. 2011. New Imaging Methods to Improve Text Legibility of Ostraca – PalArch’s Journal of Archaeology of Egypt/Egyptology, 8(2) (2011)

Abstract We report on experiments on three new methods to improve text contrast for carbon ink ostraca. These are (1) Raman imaging, (2) Micro-focus XRF scanning and (3) exogenous contrast agents either to enhance the X-ray signal or create an optical fluorescence signal. We tested all three methods with modern ‘stunt’ ostraca, made using a […]

Gregory Bearman & William A. Christens-Barry. 2009. Spectral Imaging of Ostraca. – PalArch’s Journal of Archaeology of Egypt/Egyptology, 6(7) (2009)

Abstract By analogy with ancient texts, infrared imaging of ostraca has long been employed to help improve readings. We report on extensive spectral imaging of ostraca over the visible and near infrared. Spectral imaging acquires the complete spectrum for each pixel in an image; the data can be used with an extensive set of software […]
