%X Artificial yellow pigments (lead-tin yellow type I and type II,lead antimonate yellow and lead-tin-antimony yellow) havebeen produced, starting from various recipes and from purechemicals, in different experimental conditions. The productswere analysed using micro-Raman spectroscopy.Differences in stoichiometric ratios, in melting temperaturesand in crucible typologies were examined. Other analyticaltechniques were required to characterize the stoichiometricratios of the obtained products (X-ray diffraction,scanning electron microscopy with energy dispersivespectroscopy and differential thermal analysis).The resultsare analysed and discussed in terms of correlations amongchemical composition, melting conditions and colour hue.
