title: Elemental mapping of Moroccan enameled terracotta tile works (Zellij) based on X-ray micro-analyses.
abstract: The purpose of this work is the elemental mapping of enameled terracotta samples (Zellij), produced between the 13th and 20th centuries in Morocco, collected from five different monuments from Marrakech. These pieces were analyzed by two non-destructive micro X-Ray Fluorescence (XRF) spectrometers, aiming to obtain elemental distribution and elemental composition. From the obtained spectra we have identified the main elements present in the tin-opacified lead glaze. The identification of the decoration colors is based on the different ratios between the fluorescence lines of the main component of the glaze (Pb-Lα line) and the fluorescence lines of the main components of the pigment (Co-Kα, Mn-Kα, Ni-Kα,… lines). The semi-quantitative calculations based on these ratios revealed significant differences between modern and ancient samples.
