This investigation evaluated the burn process in prehistoric ceramic from the Serra do Evaristo I,\udan archaeological site, located in Baturité, Ceará, in Northeast Brazil. The material analysis shows\udvariation in the material coloration that can indicate different burning processes. However, in a\udprehistoric and ethno-historic context of the groups from the Brazilian northeast, the usual data\udshows only the burning process in an oxidant atmosphere. Therefore, there remains a question\udconcerning whether this variation is related to different production processes of the ceramic\udmaterial or to the different types of the clays. With the objective of clarifying this question, X-Ray\udDiffractometry (RXD) petrographic analysis were performed on the material. It was verified and\udshown that the Serra do Evaristo I ceramists used two types of clays originating from two different\udplaces and that they could mix the two clay minerals according to the type of vessels that were\udproduced
