内容記述 |
At the end of the last century, many of the monumental objects of Alexandria Lighthouse were lifted out from underwater and stored or exhibited at different places in Alexandria City. Although these objects had been desalinated and cleaned after being lifted from underwater, they still suffering from the presence of a large amount of white marine encrustations and concretions deposited on their surfaces. The main aim of the present work is to define and introduce an appropriate cleaning method to remove these deposits that are still disfiguring the surface of most (if not all) of these objects. Visual examinations, polarizing microscope and XRD methods are used to define the nature and the composition of these insoluble deposits. These deposits range from white to yellowish white in color, are relatively hard (about 3-4 by the Mohs scale) and their thicknesses range from millimeters to about 1 centimeter. Microscopic examination shows the impregnation of these deposits inside the exfoliation of the stone minerals (biotite) of the granitiods monumental objects. The XRD analysis indicated that the main components of these incrustations are the calcium carbonate minerals; mainly aragonite with calcite, in addition to quartz. The Physical-chemical method of cleaning processes has been applied in our work. For the present cleaning processes, poultices formed of EDTA +CMC alone or with other mixtures were tested for removing the considered insoluble deposits. Using EDTA 20% in the form of a poultice with the help of brushes and/or fiberglass is a safe and successful method to remove the insoluble white marine deposits disfiguring the granitic monumental objects. |
