The site of Caltagirone is one of the major production center of pottery in Sicily and southern Italy, and its activity is attested since Neolithic period and is still a vivid tradition. From the specifics requirements of master craftsman to individuate the relation between the cooking process and the color of their artifacts, a project based on the study of this two parameters correlations is developed. In order to create ceramic specimens with a composition typical of the area of interest, clay were sampled in the quarry of Monte San Giorgio and in the area of Lazzaretto Conadomini furnace.
The sand used as inert was sampled from the Monte Stagno quarry; all the sites were chooses following the indications of the major ceramists of Caltagirone. In this work we present the results from the color specification of two types of mixture that characterize the Calatina production used by ceramicists to obtain, respectively, ceramics commonly used and most valuable artifacts.
The color differences were calculated in reference to the sample before cooking, settled "raw". The results obtained represent a set of objective data on color changes of ceramic specimens due to the different cooking conditions and they gave precise information for the continuation of research. The study also provides to cross the colorimetric results with those obtained by X-ray diffraction techniques. This is useful to identify, for each thermal processes, the mineralogical phases that may be responsible of the color differences measured.
Michael Romano. Thus, many archaeometallurgical studies focus on identifying and characterizing the chemical processes associated with smelting and other production steps. Whilst such studies contribute valuable data to our understandings of past craft practices they tend to focus on production debris rather than production contexts. The implication of such an approach is that contexts associated with production are often ignored in archaeometric analysis.
