Sumario:[EN] An archaeometric study of a set of glass beads found in the Veton hillfort of Ulaca –Solosancho, Ávila– has been undertaken. The samples are associated to two contexts, the necropolis and the Torreón, dated etween the 2nd and 1st centuries bc. The main goal has been determining their chemical composition, their technological characteristics including chromophores responsible for their coloration, as well as their possible geographical provenance and state of conservation. For this purpose, the ensemble was analyzed through conventional techniques such as optical stereo microscope, field emission scanning electron microscopy –fesem– coupled with energy dispersive X-ray –eds– microanalysis, and UV-Vis spectrophotometry. The results indicate that all the beads were made with a natron-based soda lime silicate glass with a low content of magnesium oxide known as lmg–low magnesium glass–. The comparison of their chemical composition with the composition of other glass beads also found in Iron Age contexts demonstrates their possible origin from the Eastern Mediterranean. In addition, it was identified a highly altered bead which is not made of glass but most likely of faience. The presence of non-local glass in both the necropolis and the Torreón suggests that this material must have been a precious good for the Veton communities that inhabited Ulaca.
