Research of flint patina from the Eastern Desert of Egypt

Abstract

The subject of patination of flint has been discussed in many scientific publications. The majority of research concentrates on the applicability of the criterion of patina thickness on determining the age of flint artefacts, as well as for studying the correlation of archaeological profiles. Detailed knowledge of the mechanisms of patination, both in terms of physical and chemical, as well as mineralogical processes, is necessary for the correct interpretation carried out for each archaeological site. The large number of factors affecting patination greatly complicates any analysis of these conditions. This publication presents the research results of desert patina developed on flint artefacts in the conditions of the Eastern Desert of Egypt. Studies indicate mineralogical and chemical variability of patina in different types of flint.
