| dc.description.abstractEn | The aim of this research is to investigate the influence of NaCl on the colours and chemical composition of Carich ceramic bodies. The addition of salt to ceramics is a practice that has been observed in several potter communities where the addition of salt is explicitly intended to whiten ceramics. In order to conduct this research and characterize the physico-chemical properties induced by the presence of salt, raw clay material and pot sherds were collected from the modern production at Hebron. Experimental bricks were made using two clayed sediments: one with a low CaO content (<10%) and one with a higher CaO content (20–25%). Different proportions of NaCl were added (up to 5%) to clay pastes which were fired at different temperatures. Mineralogy (petrography, XRD), chemistry (SEM-EDX) and colour analyses were carried out on raw clay materials, pot sherds and experimental (lab-made) bricks. SEM imagery offered the possibility to monitor the evolution of the mineralogical transformations, the pore system with increasing firing temperature and salt content. Results confirm the role of salt as a catalyst in the transformation reaction of calcium silicates during the firing process and its influence on the colour of the finished object. | |
