Alabaster is an ornamental stone that was widely used in ancient Egypt and it had a lot of
deterioration factors. The present paper deals with two types of alabaster that located at Wadi
Sannur and Wadi El Assuity, and their durability and geotechnical characteristics. These
characteristics were examined before and after artificial ageing using simple analytical methods.
Physical and mechanical properties were carried out on samples from quarries providing each
type and the same samples were then exposed to artificial ageing with sodium chloride and
heat which effectively produced deterioration comparable with that in Luxor and Karnak
temples. The results were tested on different alabaster objects from Luxor and Karnak temples
where the use of alabaster. The study was also aimed to evaluate the efficiency of the various
commercial silane-based and acrylic products in laboratory in order to recommend the
protective treatment for the conservative treatment of the alabaster. To fulfill this goal a soaking
characterization and accelerated ageing tests were performed. Quite satisfying results have
been observed, except for the original color of the alabaster samples and for particular condition
of application.
