Reactivity of earth and synthetic pigments with linseed oil

Conclusions

In clear contradiction to the data in the bibliography, 12 out of the 30 pigments studied react with linseed oil to form soaps which act as driers and accelerate the drying of linseed oil.

This work has proved this reactivity (with metallic soap formation). Furthemore, the extraction method eliminated the interference produced by pigments when the IR spectrum is carried out directly on the binder-pigment mixture sample.

This technique can be very useful in pigment identification, as well as in the study of the techniques used by artists throughout the history.
