The aim of this research is to study the deterioration resulting from burial
context on archaeological glass. Investigations were performed on a series of
Islamic glass fragments coming from different excavation sites (Deir El-Ghannam
and Deir El-Banat) in Fayoum which was a major manufacturing place for
archaeological glass during Islamic periods. The mineralogical and elemental
compositions of glass fragments and soil were determined by Energy dispersive
X-ray (EDX) methods, while glass fragments’ surfaces were examined by Scanning
Electron Microscope (SEM) and USB Digital Microscope. Deterioration aspects
resulting from being buried varied among excavations in the Fayoum, according to
chemical composition and soil moisture’s proportion which increase in Deir
El-Ghannam and decrease in Deir El-Banat. The study shows that different kinds
of salts “Chloride and Sulphate”, dirty layers, soil deposits affect the
thickness and colour of glass, on top of glass corrosion layers. This study
resulted in the conception of a methodology to treat the deterioration aspects.
