Cathodoluminescence applied to the microcharacterization of mineral materials : a present status in experimentation and interpretation
Experimentation and interpretation of cathodoluminescence (CL) microscopy and spectroscopy applied to the microcharacterization of material minerals are reviewed. The origins of the intrinsic (host…
CUERDA SECA CERAMICS FROM AL‐ANDALUS, ISLAMIC SPAIN AND PORTUGAL (10TH−12TH CENTURIES AD): INVESTIGATION WITH SEM–EDX AND CATHODOLUMINESCENCE*
Since little is known about the cuerda seca technique, our aim has been to complete an initial analysis of 11th-century cuerda seca by studying fragments from the 10th century (Pechina, Almeria) and…
Gold leaf decoration on medieval islamic glazed ceramics - in search of technological features with XRD
Considered as luxury earthenware, haft-rangi ceramics are sometimes enlightened with gold leaves. This type of decoration appears on vessels in the Iranian world in the 12th-13th centuries and is…
The Potential of EBSD and EDS for Ceramics Investigations—Case Studies on Sherds of Pre‐Columbian Pottery
The work focuses on the potential of structural and chemical examinations by scanning electron microscopy based methods for archaeometric studies on ceramics. Achieved by a single preparation…

CL and EPR data confirm that lasers — with highly controlled parameters — only get rid of the black crust and, thus, reveal the underneath layer, the so-called patina, which indicates CL to be a fast and easy way to provide a high quality control for the restoration of polluted ancient stones.
