Cobalt cerulean blue

This page presents the spectroscopic analysis of cobalt cerulean blue.
The pigment has been examined using XRF spectroscopy, Raman spectroscopy, FTIR spectroscopy, and reflectance spectroscopy. These complementary techniques provide valuable insights into the pigment’s composition and structure.
This page aims to show which analytical methods are most effective for identifying this pigment in artworks and historical materials. By comparing results across different techniques, it serves as a practical reference for heritage science, conservation, and pigment analysis.

Introduced in the 1860s, cobalt cerulean blue was extensively used by the impressionists for its fairly true blue. It is still in use.
