TECHNART 2017. Non-destructive and microanalytical techniques in art and cultural heritage. Book of abstracts
440 p.TECHNART2017 is the international biannual congress on the application of Analytical Techniques in Art and Cultural Heritage. The aim of this European conference is to provide a scientific forum to present and promote the use of analytical spectroscopic techniques in cultural heritage on a worldwide scale to stimulate contacts and exchange experiences, making a bridge between science and art.
This conference builds on the momentum of the previous TECHNART editions of Lisbon, Athens, Berlin, Amsterdam and Catania, offering an outstanding and unique opportunity for exchanging knowledge on leading edge developments.
Cultural heritage studies are interpreted in a broad sense, including pigments, stones, metal, glass, ceramics, chemometrics on artwork studies, resins, fibers, forensic applications in art, history, archaeology and conservation science.
The meeting is focused in different aspects:
- X-ray analysis (XRF, PIXE, XRD, SEM-EDX).
- Confocal X-ray microscopy (3D Micro-XRF, 3D Micro-PIXE).
- Synchrotron, ion beam and neutron based techniques/instrumentation.
- FT-IR and Raman spectroscopy.
- UV-Vis and NIR absorption/reflectance and fluorescence.
- Laser-based analytical techniques (LIBS, etc.).
- Magnetic resonance techniques.
- Chromatography (GC, HPLC) and mass spectrometry.
- Optical imaging and coherence techniques.
- Mobile spectrometry and remote sensing
Um estudo comparativo interdisciplinar das técnicas e materiais de douramento em dois conjuntos de talha dourada barrocos portugueses
The gilded polychrome carved wood in Portugal, (talha dourada) gained its most rich expression during the Baroque epoch with the development of production techniques and the use of of gold leaf. The present paper proposes a complementary and comparative study of two important complexes of talha: one from St. Alberto’s church, integrating the visiting circuit of the Museu Nacional de Arte Antiga (Lisbon), and the other from church of Vale de Figueira (Santarém district). Both complexes house talha dourada’s decoration from the 18th century, that were studied through an inter-disciplinary approach, in which analytical data (optical microscopy, fluorescent stain, XRF, SEM-EDX, micro-computerized tomography, FTIR, Matrix-Assisted Laser Desorption/Ionisation-Time of Flight Mass Spectrometry) complement historical data.El arte de la talla dorada en Portugal ganó su más rica expresión durante el período barroco a través del desarrollo de técnicas de producción y el uso de pan de oro. Este trabajo propone un estudio complementario y comparativo de dos grandes complejos de talla, el de la Iglesia de San Alberto, integra el circuito de visita del Museu Nacional de Arte Antiga en Lisboa, y el de la Iglesia de Vale Figueira, en Santarém. Los dos complejos albergan retablos dorados del siglo XVIII, que han sido estudiados a través de una metodología interdisciplinar, en la que los datos analíticos (microscopia óptica, tinción fluorescente, fluorescencia de rayos X, SEM-EDX, micro-tomografía computerizada, FTIR, MALDI-TOF-MS) complementan los datos históricos.A arte da talha dourada em Portugal ganhou a sua mais rica expressão durante a época barroca devido ao desenvolvimento das técnicas de produção e ao uso do ouro em folha.

X-ray fluorescence applied to yellow pigments based on lead, tin and antimony: comparison of laboratory and portable instrumentation
X-ray fluorescence is a diagnostic approach particularly suited to be utilized in cultural
heritage sector since it falls in the non-destructive and non-invasive analytical tools. However
there are big differences between portable and laboratory instrumentation that make difficult
to perform a comparison in terms of quality and reliability of the results. The present study is
specifically addressed to investigate these differences in respect of the same analytical
sample-set. To reach this goal a comparison was thus carried out between portable and bench
top devices X-ray fluorescence devices and techniques were used on different type of yellow
pigments based on lead, tin and antimony obtained in laboratory, reproducing the instructions
described in “old” recipes, that is: i) mortar of lead and tin produced on the basis of the recipe
13 /c V of the “Manuscript of Danzica” and “ Li tre libri dell’arte del Vasaio” by Cipriano
Piccolpasso; ii) two types of lead and tin yellow (Pb2SnO4 and PbSnO3) produced starting
from the indications of the 272 and 273 recipes of the “Bolognese Manuscript”; iii) lead
antimonate (Pb2Sb2O7) obtained by following the instructions of the Piccolpasso’s treatise
and those contained on the “Istoria delle pitture in maiolica fatte in Pesaro e ne’ luoghi
circonvicini di Giambattista Passeri” and finally iv) lead, tin and antimony yellow
(Pb2SnSbO6,5) obtained starting from the information contained in the paper 30 R of
“Manuscript of Danzica” [1].
The XRF analysis were performed using a laboratory instrumentation (Bruker M4 Tornado)
and a handset analytical device (Assing Surface Monitor). In order to perform a significant
statistical comparison among acquired and processed data, all the analyses have been carried
out utilizing the same sample, the same acquisition set up and operative conditions.
A chemometric approach, based on the utilization of Principal Component Analysis (PCA)
and multivariate analytical based tools [2], was utilized in order to verify the spectral
differences, and related informative content, among the different produced yellow pigments.
The multivariate approach on the results revealed instrumental differences between the two
systems and allowed to compare the common characteristics of the set of pigments analyzed
The Elemental Analysis of Glass Beads
Ancient glass beads as a window to the ancient world
Glass beads, both beautiful and portable, have been produced and traded globally for thousands of years. Modern archaeologists study these artifacts through sophisticated methods that analyze the glass composition, a process which can be utilized to trace bead usage through time and across regions. This book publishes open-access compositional data obtained from laser ablation – inductively coupled plasma – mass spectrometry, from a single analytical laboratory, providing a uniquely comparative data set. The geographic range includes studies of beads produced in Europe and traded widely across North America and beads from South and Southeast Asia traded around the Indian Ocean and beyond. The contributors provide new insight on the timing of interregional interactions, technologies of bead production and patterns of trade and exchange, using glass beads as a window to the past.
This volume will be a key reference for glass researchers, archaeologists, and any scholars interested in material culture and exchange; it provides a wide range of case studies in the investigation and interpretation of glass bead composition, production and exchange since ancient times.

A History of Materials and Technologies Development
The purpose of the book is to provide the students with the text that presents an introductory knowledge about the development of materials and technologies and includes the most commonly available information on human development. The idea of the publication has been generated referring to the materials taken from the organic and non-organic evolution of nature. The suggested texts might be found a purposeful tool for the University students proceeding with studying engineering due to the fact that all subjects in this particular field more or less have to cover the history and development of the studied object. It is expected that studying different materials and technologies will help the students with a better understanding of driving forces, positive and negative consequences of technological development, etc
