Abstract
The aim of this work is to investigate the methods used for producing
artificial yellow pigments (‘type I’ and ‘type II’ lead-tin yellow, lead antimonate yellow or Naples yellow, and lead-tin-antimony yellow), starting from
various recipes and the more recent literature, and to characterize the materials
produced by utilising different analytical techniques. The artificial yellow pigments were obtained from pure chemicals (PbO, Pb3O4, SnO2, Sb3O4). The effects produced were tested by varying the stoichiometric ratios,
melting temperatures and times, and crucible typologies. The powders obtained were characterized by means of SEM-EDS, XRD, XRF and DTA analyses. In order to evaluate the colour changes due to different
melting temperatures and stoichiometric ratios, the colour measurements
were taken using CIExy 1931 and CIE 1976Lab coordinates.
