Resumo
In this study, chemical and mineralogical analyses were performed on
ceramics and clay samples from Barracão archaeological site located in
Baixo São Francisco River. The chemical and mineral analysis was
performed by INAA and by means differential scanning calorimetry (DSC).
The data set was studied by means of cluster analysis and discriminant
analysis. The results showed that the raw material used in ceramics is not
local. By using DSC it was possible to discover that the principal minerals
in the samples are quartz, feldspars, mica and kaolinite. The existence of
kaolinite denotes that the firing temperature of the pottery analyzed was
lower than 500 °C. The results obtained in this study, in association with
archaeological information, allowed for the identification of the ceramic
groups relative to the ceramists occupations at Xingó area.
