Salt Analysis Of Deliquesence And Drillings From Ea 1476 And Ea 1613
EA 1476 and EA 1613 were consolidated using Dow Corning T40149and Raccanello Acrylic Silane. A period was allowed for curingto take place before further work was commenced. During July1984, deliquesence appeared on the surface of both sculptures.Prior to treatment a drilling from EA 1476 had been analysedand a chloride content of 0.08% and acid insoluble matter contentof 0.1% determined. EA 1613 was not analysed prior totreatment.Samples of deliquesence for analysis were collected on filterpaper. The filter paper was then soaked in distilled water andthe extract analysed for the presence of chloride, nitrate andsulphate. Drillings were taken from both sculptures for quantitativemeasurements of chloride and nitrate levels.The difference in chloride content determined on EA 1476before treatment and after deliquesence may be due to concentrationof chloride by moisture movements in the stoneleading to the appearance of moisture droplets on thesurface.The results are particularly interesting because it is thefirst time that the presence of nitrate has been detectedin Egyptian stones in the BM and these levels are quitehigh.
