SUYA DOYMUŞ AHŞABIN ANALİZİ: YENİKAPI BATIKLARI ÖRNEĞİ

Bu çalışmada Yenikapı Batıklarına ait ahşaplar üzerinde konservasyon çalışmalarını yönetebilmek amacıyla konservasyon öncesinde ve konservasyon esnasında gerçekleştirilen analiz çalışmaları değerlendirilmiştir1. Bu analizler maksimum su miktarı (Umax)-yoğunluk, SEM (Taramalı elektron mikroskobu), SEM-EDX (Taramalı elektron mikroskobu-enerji dağılım spektrometresi), FTIR (Fourier transform infrared spektroskopisi), XPS (X ışını fotoelektron spektroskopi) ve XRF (X Işını floresan spektroskopisi) analizlerinden oluşmaktadır. Söz konusu analizler batık ahşaplarının konservasyon işlemlerinin gerçekleştirilebilmesi amacıyla koruma işlemlerinin öncesinde ahşaplardan alınan örneklerle başlamakta kimyasal emdirme çalışmalarının tamamlandığı son aşamaya kadar devam etmektedir.

ANALYSIS OF WATERLOGGED WOODS: EXAMPLE OF YENİKAPI SHIPWRECKS

In this study, the analyses carried out before and during the conservation were evaluatedto manage the conservation works on the woods of Yenikapı Shipwrecks. The analysescomprise the maximum water content (Umax)-density, SEM (Scanning Electron Microscopy),SEM-EDX (Scanning Electron Microscopy- Energy dispersive X-ray spectroscopy), FTIR(Fourier Transform Infrared Spectroscopy), XPS (X-ray Photoelectron Spectroscopy) andXRF (X-ray Fluorescence Spectroscopy) analyses. To carry out the conservation works onthe woods of Yenikapı shipwrecks, the analyses start with the samples obtained from thewoods before the conservation works and continue until the last phase in which chemicalimpregnation processes are completed.
