• •192 FTIR spectra were collected and made available as “data-point-table” format.•A wide set of different Cultural Heritage materials were analyzed.•This dataset represents an advantageous tool for qualitative mineralogical analysis. The use of vibrational spectroscopy is gaining more and more relevance in the field of the identification and characterization of Cultural Heritage materials. In this frame we propose and discuss a copious collection of Fourier Transform Infrared (FTIR) spectra acquired in external reflectance (ER) mode (4000–400 cm−1), which is a non-destructive and inexpensive analytical technique. Up to 192 spectra were collected, processed and made free-available to the scientists and professionals working in the Cultural Heritage sector. Color and inclusions, optical anisotropy, polymorphism and isomorphism, water content, crystallinity index, polyphasicity are some properties that have driven to rationale of the paper for discriminating groups of geomaterials usually found in studies aimed at the valorization and conservation of Cultural Heritage. Finally, this study offers a robust opportunity to beginners who intend to use ERFTIR as a tool in the field of qualitative and non-destructive mineralogical analysis.
