Diagnostics of Materials of Artistic and Archaeological Interest

Structure: Department of Chemistry
Person in charge: Prof. Silvia Bruni

At the Department of Chemistry, analyses can be carried out on different materials of historical, artistic or archaeological relevance, such as inks, mortars, metallurgical slags, leather artifacts etc. The analysis can also affect deterioration products.

Below are some examples of the services available.

Analysis of pigments and binders in paintings

Non-invasive analysis in-situ and laboratory analysis (microanalysis)

Techniques and tools:

  • Portable equipment: micro-FTIR and micro-Raman techniques, micro-spectrofluorimetry and reflection in the visible spectrum
  • Laboratory tools: micro-FTIR, micro-Raman and micro-FT-Raman techniques, SEM-EDX, micro-spectrofluorimetry

Analysis of organic dyes both natural and synthetic

In-situ and laboratory analysis

Techniques and tools:

  • Portable equipment for fluorescence and reflection in the visible spectrum measurements
  • laboratory techniques for HPLC and SERS (Raman spectroscopy intensified by surface effect) possibly coupled to the TLC technique

Studies on archaeological pottery

The analysis may be aimed at identifying the provenance, firing technology and decoration

Techniques and tools:

  • spectroscopy techniques for elemental (FAAS, ICP-AES, SEM-EDX) and mineralogical (FTIR, XRD) analysis

Identification of archaeological organic residues

The analysis can be carried out on different materials such as resins, balms, oils and fats, waxes, food remains

Techniques and tools:

  • chromatographic (GC-MS) and spectroscopic (FTIR, NMR FT-Raman) techniques
