Cam örnekler öncelikle form özelliklerini yansıtacak şekilde görsel olarak tanımlanmış, fotoğraflanarak belgelenmiş ve kodlanmıştır. Cam örneklerinin yapım teknikleri hem görsel hem de taramalı mikroskop altında habbe şekillerine göre belirlenmeye çalışılmıştır. Örneklerin element ve mineralojik içerikleri taşınabilir Enerji dağılımlı X-ışınları floresans spektroskopi (P-EDXRF) ve Taramalı Elektron Mikroskobu-Enerji Dağılımlı Spektroskopi (SEM-EDS) yöntemleri ile analiz edilmiştir. Analiz sonuçları cam örneklerin 7 tanesi soda camı iken diğer 7 si potasyum kireç camı olduğu anlaşılmıştır. Örneklerin yüksek Si içerikleri, camların hem mekanik direnç ve dayanıklılığın, hem de ergime sıcaklığının yüksek oluşuna işaret etmektedir. Cam örneklerin üretiminde bir örnek hariç bitki külü (K ve/veya Mg) kullanılmamıştır. Cam örneklerin Al içeriklerindeki farklılık örneklerin hammadde adresini ayrı kaynaklara dayandırmaktadır. Sr ve Zr’nin tespit edilmemiş veya düşük oranlarda olması karasal hammadde kullanılmış olduğunu göstermektedir. Camlarda renk veren elementler; Fe, Co, Mn ve Cu’durÖğe New perspective in authenticity, restoration and characterization of cultural heritage by using new archaeometric techniques(ICOMOS, 2014) Karadağ, Recep; Akyol, Ali Akın; Aydın, MahmutÖğe UNESCO - Cultural Heritage Protection Handbook: CorePrinciples for Preventive Conservation Risk Management(UNESCO, 2017) Aydın, Mahmut; Güner, SaadetÖğe Determining the authenticity of coins by using non destructive archaeometric techniques(Interpol, 2012) Aydın, MahmutÖğe Identification by SEM EDX analyses of ceramics found in the Roma Theatre excavation in Ankara Turkey(METU, 2014-06-03,05) Aydın, Mahmut; Torgan, Emine; Karadağ, RecepSüleymaniye Mosque (1550-1557) is an inspirational edifıce for many fıelds such as architectural acoııstics and materials Science. In its original state. thc mastery of acoııstics vvithin the Mosque is a coınmon belief. Due to the scarcity of knovvledge on its authentic acoustical features, comprehensive studies are needed to assess the acoııstical conditions of the Mosque in relation to its architectural elements and interior fmishing materials contributing to those features. In the context of this study acoustical simulation that relies on recent field tests are carried on. The combined interpretation of the overall architectural and acoustical data exhibited the presence of very high reverberation time values, especially at low frequencies, for the cıırrent state. As the previous fıeld tests presented the unoccupied condition of the Mosque, the acoustical simulations are performed initially to discuss sonıe activity patterns for the occupied state, and later to experiment the effects of historical lime-based plasters on the acoııstics of the Mosque. Considerable improvement in the sound field of the main prayer zone are observed due to the replacement of cıırrent cement-based plasters with the historical lime-based ones, collected from some other structures of the same era. The results pointed out the necessity of further investigations on historical lime-based plasters in terms of their acoustical performances and raw materials characteristics in order to scientifıcally prove their contribution to the acoustical features of Süleymaniye Mosque and to re-achieve its original acoustical comfort conditions.Öğe Fighting against illicit traffic and forgeries of metal objects: The situation in Turkey(MCSER Publishing, 2016-03-08) Aydın, MahmutProtection of collection items belonging to museum or private collectors against fakes, forgeries and illicit traffic of cultural heritage is mostly done by archaeologists using visual inspection. Because of advanced technologies used in imitations of 20- 21st century made the task of archaeologists more difficult resulting in increased need for the employment of scientific techniques. In this respect, we need archaeometry laboratories that are fully armed with sophisticated archaeometric tools and technical knowledge. Moreover, there is also an obvious need for detailed legislation and relevant laws to be amended for fight against forgery and illicit traffic of the cultural objects at national and international level. Turkey is rich in historical monuments, antiques and ruins resulting in abundant museums and ancient objects. Being a geographical bridge between the western and the eastern world, she is also a bridge for international illicit, cultural heritage traffic and forgers. On the other hand, it is not able to build enough necessary archaeometrical infrastructures to support archaeological ones for determining authenticity and preventing misconduct regarding cultural heritage objects for museums, customs houses and so on. This study will discuss novel archaeometric techniques on authenticity determination of metal artefacts and preventing replacement of them with fake objects. Beside this, usage of non-destructive archaeometric techniques will be discussed for fighting with illicit traffic of cultural heritage, proving ownership and returning of objects. Moreover the application of methodology is explained on an international illicit traffic and forgery example of Golden Winged Sea Horse that was solved by the author.Öğe Using technology against theft and forgery of cultural heritage goods(MCSER-Mediterranean Center of Social and Educational Research, 2014-09-01) Aydın, MahmutThe aim of this study is to evaluate problems of museums and collectors that buy cultural heritage objects from individuals without asking a certificate of authenticity. Keeping collection of museums authentic is going to be more difficult because of developed replication technologies used by forgers who want to sell fake objects to museums and collectors. Moreover because of ill intended museum personnel who want to replace authentic objects with fake. In order to overcome such problems, it is necessary to get chemical composition of cultural heritage objects. Cultural heritage objects are sensitive and unique so the technique that is going to be used in analysis of such objects must be non-invasive. Portable Energy Dispersive X-Ray Florescence (P-EDXRF) lets scientists analyze cultural heritage in a non-destructive way. Determination of chemical composition of objects in quite short times such as 30 seconds per analysis) and seeing qualitative and quantitative results simultaneously is possible. Results of P-EDXRF can be used in determination of authenticity, provenance studies, getting information about production technology of analyzed objects and for restoration purposes. Moreover, P-EDXRF lets scientist make multiple analyzes, especially from big objects as it is non-invasive, fast and cheap. Besides, due to spectrometers being as light as 2 kg, it is portable and enables in situ analyses in museums or wherever objects are being kept. Characterization of cultural objects let museums keep chemical composition of objects in the inventory books. Chemical composition of object would act as the fingerprint of the objects. Therefore P-EDXRF results can be used to determine if an authentic object in the collection was changed with a fake one or not. These can be done by comparing new chemical composition of suspected existing cultural heritage objects and chemical composition that record in inventory book. Moreover in case of a museum robbery, recorded analysis results of stolen objects can be used to prove authenticity of recovered items. Majority of the time, after museum robberies fakes of stolen objects are made by forgers and are tried to be sold to collectors or museums. PEDXRF also used for restoration with the aim of detecting the chemical composition of the artifact. In authenticity studies SEMEDX also is widely used to determine chemical composition and matrix morphology of the objects.Öğe Animals at Burgaz in the clasical and hellenistic period from the evidence of faunal remains(Batman Üniversitesi, 2015) Aydın, MahmutBu çalışmada antik Burgaz yerleşkesinden arkeolojik kazılar sonucunda ele geçen kemikler incelenmiştir. Kemiklerin incelenmesi sonucunda hayvan kullanımı, insanların beslenmesi, sosyal farklılaşma, Burgaz ve Datça’nın Klasik Dönem çevre ve bitki örtüsü hakkında bilgi edinildi. Bunun yanı sıra diğer merkezlerden farklı olarak hayvan kullanımının bölgesel bir özellik gösterip göstermediği tartışılmıştır. Bu tür araştırmalar klasik arkeoloji eğitimi alan arkeologlar arasında pek yaygın değildir bundan dolayı kemik araştırma metodolojisi ve laboratuar çalışmasının her safhasını yazdım. Burgaz bir deniz kıyı yerleşmesi olmasına rağmen deniz ürünleri Burgaz sakinlerinin diyetlerinde önemli bir yer tutmamaktadır. Burgaz kemiklerinin analiz sonuçlarına göre şu hayvan türleri tespit edilmiştir: sığır, koyun/keçi, domuz, at, eşek, kopek, yabani keçi, yabani domuz, kızıl geyik, kuş deniz ürünlerinde ise balık ve deniz hayvanı kabuğudur.
