SCIENTIFIC EVALUATION OF SOME CONSOLIDATION MATERIALS OF EXCAVATED ARCHAEOLOGICAL POTTERY FROM THE REGION OF TEL PASTA AT SHARQIA IN THE EAST OF DELTA

Abstract

Many of the archaeological pottery objects excavated from the archaeological sites have sufferedfrom different phenomena of deterioration. This kind of pottery needs a consolidation process forimproving the physical and mechanical properties. Some archaeological pottery samples wereobtained from the region of Tel pasta at Sharqia in the East of Delta, dating back to the Ptolemaicage. The pottery samples used in the study represent different models from the site for their use inLaboratory study. Scientific laboratory evaluation of some acrylic and silicon consolidationmaterials were done such as Monomer Poly Methyl Methacrylate, Paraloid B- 82, Ethyl SilicateCopolymer AS 21, a mixture of Ethyl Silicate Copolymer AS 21 and Paraloid B-82 and Tegovakon.Many experiments, tests and different examinations were done on The treated pottery samplessuch as determination of physical and mechanical properties, the examination of scanning electronmicroscope and thermal, light artificial ageing processes. Tests and experiments have all provedthat one of two consolidants (First, a mixture of ethyl silicate copolymer AS21 and Paraloid B-82 ata rate of 1:1. Second, ethyl silicate copolymer AS21) must be used to consolidate archaeologicalpottery discovered from damp soil.
