ABOUT

TecnArt, established in 2012 as academic Spin off of the University of Torino, works in the field of diagnostics applied to Cultural Heritage.
The founder members – Conservations Scientists – have specific university education and experience focused on the application of scientific techniques to Cultural Heritage.
The professional aim is constantly oriented to respond as best as possible to the questions and problems from the clients. This is feasible also thanks to the consolidated network of partnerships established with other laboratories and experts from different fields.

SERVICES

TecnArt provides a set of services dedicated to the authentication and dating of ancient findings, to the analysis of materials constituting artworks and to the study of their conservation conditions, in addition to providing scientific advice flanking several professionals in the field.
For the execution of the scientific investigations we mainly make use of the laboratories and instruments of the University of Turin.
All services are aimed at both public institutions and private clients.

DATING

THERMOLUMINESCENCE – Authenticity testing and dating

Thermoluminescence (TL) is an absolute dating technique that allows to date (or authenticate) the ceramic material. Therefore, the applications can be useful for simple authenticity testing in case of decontextualized artefacts or complete dating in case of archaeological sites and structures.

Authenticity testing

It is applied to decontextualized artefacts, so it is sufficient to verify their compatibility with the stylistic attribution (and therefore exclude or confirm it can be a forgery).
The materials that can be analysed, taking a sample from the artefact, are pottery/earthenware, porcelain and casting cores of bronzes.

Dating

TL dating is carried out on structures or ceramic elements in which the context is known (e.g. an archaeological excavation). It requires some grams of material, as well as numerous experimental measurements, also including in situ environmental radioactivity measurement. The margin of error achievable on the final dating ranges from 5% to 10%, depending on several factors.

RADIOCARBON DATING (14C)

Radiocarbon method allows the dating of organic artefacts such as wood, charcoal, seeds, bones, textiles.
Thanks to the AMS technique (Accelerator Mass Spectrometry), which requires the use of a particle accelerator and a few milligrams of material (it varies according to the type of material), it is possible to date finds until about 50 thousand years, with a precision ranging approximately ±40 years for ancient finds. Furthermore, for recent periods, after 1950, interesting applications can be obtained by using the so-called “bomb peak”.
For this service TecnArt provides the scientific advice, the sampling and the delivery of the final report with the results, whereas the preparation and measurement of the sample are entrusted to the main Italian laboratories carring out this type of analysis.

LABORATORY ANALYSIS

Facing finds or artworks, the questions can be various, aimed at the general understanding of the artefact and its state of conservation or focused on specific aspects, integrating larger studies.
In addition to providing the analyses listed below, TecnArt, thanks to the consolidated network of partnerships with qualified experts, commits to integrate its services to fully respond to the needs that presents the specific case.

  • ANALYSIS WITH OPTICAL MICROSCOPY AND SCANNING ELECTRON MICROSCOPY (SEM-EDX) – microstratigraphic study, sample characterisation such as textile fibre, paper, etc…
  • X-RAY FLUORESCENCE (XRF)
  • DIGITAL RADIOGRAPHY AND TOMOGRAPHY
  • RAMAN SPECTROSCOPY
  • INFRARED SPECTROSCOPY
  • GAS CROMATOGRAPHY (PY-GC/MS)
  • BIOLOGICAL ANALYSES

SCIENTIFIC ADVICE

Scientific advice are provided, also at international level, to the several professionals in the field (such as archaeologists, restorers, experts, etc.) on the scientific planning of diagnostic interventions and in general on the technical approach to be adopted to better respond to the needs and to the problems of the case study.

Furthermore, TecnArt provides technical advice on the laboratories set up for thermoluminescence dating, also guaranteeing the staff training to launch the laboratory up to make it independent.

PROJECTS

BE-ARCHAEO


BEyond ARCHAEOlogy: an advanced approach linking East to West through science, field archaeology, interactive museum experiences

European project funded in the work program Horizon 2020 – Marie Skłodowska-Curie Actions.

ANIMAL MUMMIES PROJECT

Study and conservation of the collection of animal mummies, promoted and financed by the Egyptian Museum, with the protection of the Soprintendenza Archeologia, Belle Arti, Paesaggio per la Città Metropolitana di Torino.
The realisation of the project has been entrusted to the temporary cluster of which TecnArt is part -dealing with the diagnostic phase- together with the restorer Cinzia Oliva and Consorzio Croma.

MYANMAR

International cooperation project for setting up a thermoluminescence dating laboratory and the training of local staff.

The involved partners are: Ministry of Culture of Myanmar, Physics Department of the University of Turin, Italian National Institute of Nuclear Physics (INFN), IPSES S.r.l. and Fondazione Lerici.
