Studio colorimetrico di un repertorio di ceramiche provenienti dal sito archeologico di Tell Barri (Siria)

In the framework of the TEMART project (Tecniche avanzate per la conoscenza materica e la conservazione del patrimonio storico-artistico), a colorimetric study was undertaken on 36 sherds of archaelogical pottery coming from the site of Tell Barri (Syria). Samples consisted in a very heterogeneous group of sherds datable between the first half of the third and the beginning of the first millennium B.C.. Many kinds of North-Syrian ceramic categories like stone ware, fine and luxury wares, Khabur ware and Ninivite V are represented. Colour measurements was used as a means of evaluating maximum firing temperatures and other technological issues of every sample. Powders taken from each sherds were submitted to six refiring steps reaching different maximum temperature (from 600°C to 1100°C). CIE L*a*b* and CIE L*C*h colour coordinates were used also to create colour curves used to discriminate between products made up from different kinds of clay.
