İzmir’de bir Osmanlı dönemi konağının tavan ve duvar resimlerinin yapım tekniği ve malzeme özellikleri

Abstract

 19 th century oil based wall paintings  Materials of historic wall paints  Pigment characterization Figure A. Stratigraphy of ceiling and wall paintings and mineralogical composition of pigments Purpose: The aim of this study was the determination of execution technique and materials characteristics of wall paintings of an almost disappearing cultural asset by documenting the authentic execution technique and material characteristics of the ornaments and provide data for the restoration work of the building. Theory and Methods:Analyses of the study were conducted on the samples that were taken from the building before the devastating fire. Microstructural characteristics, mineralogical and chemical compositions of plasters, priming layer, binding material and paints that were used in wall paintings have been determined by using optical microscopy, infrared spectroscopy (FTIR), X-Ray diffraction analysis (XRD) and scanning electron microscopy (SEM equipped with EDS). Results:Yahya Hayati Paşa Mansion in Bayraklı, which was built by Architect Andon Gavano in 1873, is one of the outstanding examples of 19 th century İzmir mansions. The building was heavily damaged due to devastating fire in 2010 and floors, ceilings and the roof of the building were completely destroyed. The study revealed that the paintings of Yahya Hayati Paşa Mansion were executed on lime plasters by using oil painting technique. Four preparatory layers on wall paintings and a single priming layer on ceiling paintings were determined by SEM and optical microscopy analyses. Organic binder, chalk, gypsum, zinc oxide, lead white and barium white were the ingredients determined in preparatory layers. Pigments of the paintings, in which brown, green, red and blue colors were dominantly used, were determined by SEM, XRD and FTIR analyses. Pigments used in paintings were determined as vermillion (HgS) for red, ultramarine (Na6-10Al6Si6O24S2-4) for blue, emerald green (3Cu(AsO2)2.Cu(CH3COO)2) for green and red ochre (Fe2O3+Clay minerals) for reddish brown. Beside these main pigments the use of barium white (BaSO4) as an extender in green paints and anglesite (PbSO4) as an alteration product of red lead (Pb3O4) in red paints were determined. Conclusion:The study documents the characteristics of painted decorations of a late Ottoman mansion by determining the stratigraphy, painting technique and pigments that make up the color palette and reveals the similarities with contemporaries in Europe.
