A lecture on the system of using one of the crystallization inhibitors “sodium ferrosanide” to remove salts off the stones

‘The Sharjah Archaeology Authority (SAA) organized a seminar entitled “The use of salt crystallization inhibitors – sodium ferrocyanide – to remove salts from rocks”, which was presented remotely through the zoom program by Dr. Yazan Abu al Hassan, specialist in archaeological restoration at Sharjah Archaeology Authority (SAA). The lecturer presented the system of using one of the crystallization inhibitors “sodium ferrosanide” that he used in the Jordanian city of Petra, explaining that the mechanism of salt damage represents a strong and widespread threat to cultural heritage, and talked about the impact of a wide range of surrounding environmental conditions, which include complex processes and mechanisms as a result of the dynamic interaction of salts with rocks, and then lead to their damage and collapse. The search for new ways to reduce salt damage to cultural heritage and improve the methods used is an urgent need to protect our cultural heritage, of which the lecturer mentioned the method of using crystallization inhibitors, which represents a practical method to protect the stone from damage and extinction, the lecturer found that the ideal solution to reduce the risk of salts to cultural heritage and protect it from loss and extinction is to introduce a solution of inhibitors in certain concentrations inside stones that contain salts and suffer damage and destruction , which in turn interact with the salts and changes its crystalline form, resulting in it emerging from the inside of the stone and crystallizing on the outside in a fragile, incoherent and easy to remove form without any effect on the stone itself. The lecturer stated that this procedure can be applied to cultural heritage stone, which suffers from the same conditions of damage due to salt.

A lecture on “The Documentary value of images of Islamic manuscripts in the fields of Architecture, Art and history”

‘The Sharjah Archaeology Authority (SAA) organized today 15/6/2020 a virtual lecture via Zoom program, entitled: “”The Documentary value of images of Islamic manuscripts in the fields of Architecture, Art and history”” presented by : archaeologist Dr. Hayam Zakaria al-Saeed, in which she mentioned examples of manuscripts that she observed within her field of study, focusing on Islamic architecture, city planning, and engineering designs of war castles. Dr. Sabah Abboud Jassim, director general of Sharjah Antiquities Authority, said: “the dominant trend now is tele-lectures, in which a large number of followers participate, and the current pandemic is charting a technical development of indirect lecture systems presented by professionals in their respective sciences.”

Lecture on physical techniques in Archeology

‘ Sharjah Archaeology Authority (SAA), organized a new lecture via “Zoom” system, presented by Dr. Atta Al Manan Ja’far, head of the Department of Applied Physics and Astronomy, Faculty of Science, University of Sharjah, under the title “physical techniques in archaeology”. The lecture sheds light on the techniques available for archaeological history, from radiocarbon to electronic resonance, as well as the analysis techniques represented by X-ray, isotope analysis, and other techniques in the science of analysis, The lecturer said: a real breakthrough in archaeology occurred in the mid-twentieth century when geophysical survey techniques were used in the discovery of several archaeological sites buried underground. The lecturer considered that these techniques are one of the most important means of studying antiquities for the purpose of discovering, preserving, restoring, or rooting them, and the objectives of studying them, and taking note of everything related to this science, the lecturer touched on the value of monuments historically, tourism, cultural, religious, economic, and aesthetic, and he presented a number of archaeological assets and finds which are available in archaeological sites in the emirate of Sharjah. The number of attendees reached 100 including specialists, scholars and observers, and their questions and inquiries varied. They learnt from this lecture precious knowledge on archeology and its outputs.
