Materials identification in works of art is a fundamental step for understanding an object’s history or an artist’s technique. Comprehensive characterization and diagnosis of the various constituent materials in artworks can provide valuable information on the artist’s working methods, as well as significant evidence for dating, provenance attribution, or forgery detection. The development of 𝐝𝐚𝐭𝐚𝐛𝐚𝐬𝐞𝐬 with high-quality data on the pure substances used as artists’ materials is of utmost importance for the identification and characterization of unknown samples. However, there are relatively few open-access spectra libraries dedicated exclusively to the cultural heritage field.
The 𝐈𝐍𝐅𝐑𝐀-𝐀𝐑𝐓 𝐒𝐩𝐞𝐜𝐭𝐫𝐚𝐥 𝐋𝐢𝐛𝐫𝐚𝐫𝐲 is an open access integrated spectral library, of art-related materials, that was designed by CERTO – INOE 2000 as a digital support tool for research specialists and other heritage-related professionals that work with non- or minimally invasive spectroscopic techniques. https://infraart.inoe.ro
The INFRA-ART database contains at this moment over 680 𝐫𝐞𝐟𝐞𝐫𝐞𝐧𝐜𝐞 𝐦𝐚𝐭𝐞𝐫𝐢𝐚𝐥𝐬 specifically used by artists – from natural mineral pigments used since prehistoric times, to modern synthetic organic pigments and dyes introduced starting with the 20th century.
The database integrates at this moment primary 𝐀𝐓𝐑-𝐅𝐓𝐈𝐑 and 𝐗𝐑𝐅 spectra, and a preliminary dataset of 𝐑𝐚𝐦𝐚𝐧 spectra. The implementation of a bottom-up architecture allows further extensions of the database with other types of analysis, 𝐋𝐈𝐅 (Laser Induced Fluorescence) and 𝐡𝐲𝐩𝐞𝐫𝐬𝐩𝐞𝐜𝐭𝐫𝐚𝐥 data, registered on well know historical pigments as well as on paint mockups, being among the new uploads planned to be carried out by the end of this year.

To support universal access and the reuse of scientific data, the database follows the European Commission’s recommendation on access to scientific information as well as the 𝐅𝐀𝐈𝐑 (Findable, Accessible, Interoperable, Reusable) Guiding Principles on research data that result from publicly funded research. The INFRA-ART Spectral Library is registered as a resource within the 𝐎𝐩𝐞𝐧 𝐒𝐜𝐢𝐞𝐧𝐜𝐞 𝐂𝐥𝐨𝐮𝐝 (𝐄𝐎𝐒𝐂) 𝐏𝐨𝐫𝐭𝐚𝐥, and 𝐫𝐞𝟑𝐝𝐚𝐭𝐚.𝐨𝐫𝐠, and is currently part of the services offered by the 𝐑𝐨𝐦𝐚𝐧𝐢𝐚𝐧 𝐡𝐮𝐛 within 𝐄-𝐑𝐈𝐇𝐒 (European Research Infrastructure for Heritage Science) 𝐃𝐈𝐆𝐈𝐋𝐀𝐁.
