Study of Various Deterioration Phenomena in Archaeological Stone Minbar, Its Causes and Treatment Methods Applied on a selected object

Abstract

The present work deals with the study on various deterioration factors and novel materials used for conservation of stone minbar. the results of the present study are summarized in five chapters that are given as following: - Chapter one: Archaeological and Technical Study of Archaeological Stone Minbars This chapter recognizes historical background of minbar, definitions and its importance as ritual furniture, symbolism and features. On the other hand, the second section of this chapter introduces the used technical and decoration techniques. It also sheds light on the most important samples of stone minbar in Egypt and all-over Islamic world. Chapter Two: Physiochemical, Mechanical Properties of construction Materials of Archaeological Stone Minbars. This chapter deals with the physical, chemical and mechanical properties of construction materials of stone minbar. the methods of the investigations and analyses such as (XRF – XRD – PLM – DLM – SM – SEM – TEM) used to determine the composition of construction materials of stone minbar also for characterization of deterioration aspects. Chapter Three: Factors and Mechanisms of Deterioration of Archaeological Stone Minbars This chapter presents the most important factors and its mechanisms of deterioration on stone minbar. The wrong conservation interventions are the most obviously factor. Chapter Four: The Experimental Study of Archaeological Stone Minbars Materials In this chapter recognize the laboratory studies, as several experiments have been carried out to evaluate the efficiency of treatment materials. Many novel consolidants enhanced with nano materials proposed according to previous studies, before and after consolidation processes of aged specimens physical and mechanical properties characterized to choose the best and the most effective consolidant. Chapter Five: Conservation of Sariet Al-Gabal Stone Minbar Stone minbar of Sariet Al-Gabal selected to apply the most effective enhanced consolidant with nano materials. the conservation intervention like cleaning, completion, insulation. we reduce the intervention to achieve good maintenance. Seleted area of minbar cleanied physically and chemically and consolidated to be approved to apply to all minbar.
