For those who take the 5 days train­ing course it is pro­vided a free Pig­ments checker. This is a col­lec­tion of swatches of 54 his­tor­i­cal pig­ments that have been applied using gum Ara­bic as a binder on a cel­lu­lose and cot­ton water­color paper, acids and lignin free, com­mer­cial­ized by “Fab­ri­ano”, 270gr/m2. This paper is not treated with opti­cal bright­en­ers, it’s slightlyUV Flu­o­res­cent, and it reflects IR. Two cross-hair lines, 0,2 mm (ver­ti­cal) and 0.4 mm (hor­i­zon­tal), were printed on each swatch of paper before the appli­ca­tion of paint, in order to have a means to eval­u­ate the pig­ment trans­parency in the IR and IRR imag­ing. The pig­ments were mulled into the binder which was added as needed for each pig­ment and applied with brush. The table below shows the list of pig­ments used. Among all the pig­ments and their vari­eties ever used in art these pig­ments col­lec­tion is not exhaus­tive but it attempts, at least, to be a selec­tion of the most used ones from antiq­uity to early 1950’. A swatch of just gum Ara­bic is added as a ref­er­ence for the binder. This Pig­ments checker was pub­lished on: A. Cosentino “Iden­ti­fi­ca­tion of pig­ments by mul­ti­spec­tral imag­ing a flow­chart method” Her­itage Sci­ence, 2:8, 2014.

Mini checker

Mini Pig­ments Checker. This is a free­bie for train­ing course lesser than 5 days. It con­tains a smaller num­ber of pig­ments cho­sen in order to show­case the work­flow for the iden­ti­fi­ca­tion of pig­ments by mul­ti­spec­tral imaging.
