Le but de ce travail est l'étude de la provenance des colorants bleus au cobalt utilisés par les verriers, de l'Age du Bronze jusqu'au XVIIIe siècle. Les premiers résultats que nous présentons ici concernent essentiellement les verres médiévaux d'ateliers du sud et de l'est de la France. Ces résultats nous permettent à la fois de mettre en évidence l'existence de quatre principaux types de minerais de cobalt parmi les verres étudiés et de préciser les périodes d'utilisation et l'origine de certains d'entre eux.
A non‐destructive bulk analytical method based on instrumental neutron activation techniques was developed to study Islamic glass weights and stamps. Three different successive irradiations are necessary. A calibration method and a calculation program have been developed in order to correct both the different observed interferences and geometrical factors. A good relationship was formed between the chronological classification of the objects and the compositional groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
