Painting Materials Analysis To recognize the made use of pigments and to study the complicated structure of painting materials, an method according to non-invasive and micro-invasive techniques approach inside a two-step sequence was applied as offered in standard protocols for conservation purposes [15], starting from non-invasive multispectral analysis around the entire object, and subsequently, on chosen samples. For the characterization of painting supplies 3 typologies of non-invasive analysis tactics have been employed: Aztreonam manufacturer visible fluorescence induced by ultraviolet radiation (UVF), infrared reflectography (IRR) and visible-induced infrared luminescence (VIL). UVF is useful for the identification of diverse supplies around the surface that are not quickly discerned employing visible light, like earlier conservation treatments. IRR uses the close to infrared to investigate below the paint EGF Protein Description layers and to highlight the prospective presence of preparatory drawings or other pictorial components. In addition, it might be combined with visible light photographs to produce false colour (IRFC) photos, which is often employed to tentatively determine pigments. Ultimately, the VIL technique is primarily made use of to identify the presence of Egyptian blue. In each of the instances the Adobe Photoshop (Adobe, San Jose, CA, USA) computer software was made use of for the post-production of photos. UVF pictures had been captured by suggests of a Xnite Nikon D810 camera (Nikon Corporation, Tokyo, Japan) coupled using a PECA 916 digital filter (Peca Goods Inc., Beloit, WI, USA). The illumination was obtained by suggests of two UV Labinospot lamps UV light MPXL and UV FLOODLIGHT (Labino, Stockholm, Sweden) with emission peak at 365 nm. A white standard Spectralon(Labsphere Inc., NH, USA, nominal reflectante: 99 in the field of imaging) was utilized for the white balance. To carry out IRR pictures, the sculpture was illuminated by m.
