On the Use of Isotope Mass Spectrometry in the Identification of Artists' Pigments

Studies in Conservation, 1970
AbstractThe principles of isotope mass spectrometry are described as a means of identifying sources of artists’ materials. Four elements are considered: lead, sulfur, carbon and oxygen. For the first two of these, preliminary results show promise in dating samples of lead white and discerning between artificial ultramarine and natural ultramarine from ...

Computer-assisted Pigment Identification in Artworks

2007
False-color infrared represents a well known method for non-invasive pigment identification in artworks. This is particularly useful in the field of conservation of cultural heritage as it provides useful information about painting materials, techniques, retouches.

Identification of pigmented gram negative bacilli.

Health laboratory science, 1978
Identification of chromogenic gram-negative bacilli on the basis of pigment production as a taxonomic criterion is unreliable. Because of this, a wide range of morphological, cultural and biochemical characteristics of bacteria in this category was examined.

Infrared Spectra in Identification of Painting Pigments

2009
Spektroskopski podaci u svijetu nalaze široku primjenu u identifikaciji pigmenata na predmetima različitog podrijetla i sastava, primjerice na manuskriptima, umjetničkim slikama, arheološkim ostatcima keramike i slično. Time se doprinosi rješavanju problema restauriranja, konzerviranja, datiranja i autentificiranja istraživanih predmeta. Analizirana su
