The specimens studied in the present work consist of five terracotta fragments from an archaeological dig on the Libyan Tadrart Acacus massif, dating back to about 5000-8000 B. C. The specimens were analysed using thermogravimetric analysis (TG, DTG), differential thermal analysis (DTA), thermomechanical analysis (TMA), X-ray diffractometry, IR spectrophotometry and inductively coupled plasma spectroscopy (ICP). Analyses were aimed in particular to determine the most striking aspect of the finds, the difference in colour between the outer surface ( reddish) and the darker inner portion of several of the specimens. The other main points investigated and discussed are related to the firing temperature and chemical and mineralogical composition, of terracotta specimens.

Abstract
The specimens studied in the present work consist of five terracotta fragments from an archaeological dig on the Libyan Tadrart Acacus massif, dating back to about 5000-8000 B. C. The specimens were analysed using thermogravimetric analysis (TG, DTG), differential thermal analysis (DTA), thermomechanical analysis (TMA), X-ray diffractometry, IR spectrophotometry and inductively coupled plasma spectroscopy (ICP). Analyses were aimed in particular to determine the most striking aspect of the finds, the difference in colour between the outer surface ( reddish) and the darker inner portion of several of the specimens. The other main points investigated and discussed are related to the firing temperature and chemical and mineralogical composition, of terracotta specimens.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
