Cuatro cerámicas con epigrafía árabe del Museu de Borriana
En este trabajo se da a conocer una muestra de las más destacadas cerámicas de época almohade que se conservan en el Museo Arqueológico de Borriana y que proceden de excavaciones arqueológicas realizadas en la ciudad y su entorno. Se presta especial atención a la decoración epigráfica pintada o incisa sobre la arcilla fresca y la estampillada. Del análisis de su decoración epigráfica se ha extraído información de notable interés que complementa aquella directamente derivada del análisis tipológico. This paper will present a sample of the most outstanding Almohad ceramics that are preserved in the Archaeological Museum of Borriana. These pieces have been found during the archaeological excav…
Dating of Archaeological Gold by Means of Solid State Electrochemistry
[EN] In archaeology and history of art, age determination is a fundamental analytical problem. While several techniques for age determination of various materials, like radiocarbon dating, are established, these methods cannot be applied for metals, for which new techniques have to be developed. For the first time a dating method for archaeological gold objects is described which is based on a corrosion clock and electrochemical measurements, using the voltammetry of immobilized particles. Samples are prepared by one touch' with a graphite pencil, only transferring a few nanograms of the archaeological gold. The method has been calibrated with the help of a series of well-documented gold sp…
