6. On the formation of hörnesite in a Fatimid manuscript folio

Author

Dyke, Yana, Centeno, Silvia, Carò, Federico, Frantz, James, and Wypyski, Mark

Abstract

A folio fragment attributed to the Fatimid period in Egypt was found to bear tufts of white crystals associated with the orange-brown and yellow paints. Raman spectroscopy identified a mixture of arsenic sulfide-based pigments in the orange-brown and yellow areas, along with vermilion in the outlines of the figures. X-ray microdiffraction, Raman spectroscopy, and energy-dispersive X-ray spectrometry identified the white crystals as hörnesite [Mg3(AsO4)2·8H2O]. Synthesis of this compound at ambient temperature and elevated relative humidity over a period of 3 years, on paper painted with arsenic sulfide pigments and treated with magnesium carbonate, suggests the possibility that a magnesium-based deacidification treatment may have contributed to the formation of this phase on the folio fragment. This work highlights the potential damage that may be sustained by arsenic sulfide-based media through exposure to deacidifying suspensions such as the ones often used in the past to treat works of art on paper and historic documents.

8. Casting Light on the Surface, Scientific Exactitude Meets Poetic Inspiration: A Close Look at Six Objects from the Islamic Collection of The Metropolitan Museum of Art.

Author

VAN DYKE, YANA

Abstract

The article looks at six objects from the collections of the Metropolitan Museum of Art in New York City related to Islamic papermaking and book arts. These include two folios from a manuscript of the Qu'ran, a page of calligraphy from a book of poetry by Sa'di and Hafiz, and the frontispiece to an album of calligraphies. Particular focus is given to papermaking technology and techniques. Topics discussed include paper sizing, negative space, and manuscript illumination.
