Were made twentyfive soils-test specimen collection and the study was performed to differentiate the mat laugh materials of variaveis processing of mathing raw materials in the factory The product mica monkeys by extrusion and pressing. The results were obtained ap s as analyzes: grain size, index of plasticity, fluoresce incidence X-ray difration the X-ray, and analyzes thermicals and properties technological. through s of curves gresifica returned to was a comparison between the retro the linear, absorb to water, porosity and bulk density. the results show that the excellent distribution and character acceptable available for the processing of the structure color dark red. needing, therefore, of the mixture of a less plastic clay with thick granulation, that works as plasticity reducer. In spite of the different resignation forms for prensagem and extrusion, the characteristics of absorption of water and rupture tension the flexing was shown inside of the patterns of ABNT / A limita??o de informa??es sobre as caracter?sticas f?sicas, qu?micas, mineral?gicas e mec?nicas da mat?ria-prima usada no processo de fabrica??o dos produtos cer?micos na regi?o do Cariri, mais precisamente na cidade do Crato, estado do Cear?, motivou o desenvolvimento deste trabalho, visto que nesta regi?o existem cer?micas que num contexto geral figuram como cadeias produtivas importantes no estado. Foram confeccionados vinte e cinco corpos-de-prova da amostra coletada para cada m?todo de conforma??o e foi realizado o estudo das vari?veis de processamento das mat?riasprimas na fabrica??o de produtos cer?micos por extrus?o e prensagem. Os resultados foram obtidos ap?s as an?lises de: granulometria, ?ndice de plasticidade, fluoresc?ncia de raios X, difra??o de raios X, an?lises t?rmicas e propriedades tecnol?gicas. Atrav?s das curvas de gresifica??o obteve-se um comparativo entre a retra??o linear de queima, absor??o de ?gua, porosidade e massa espec?fica aparente. Os resultados mostram que a mat?ria-prima tem excelente distribui??o e caracter?sticas aceit?veis para o processamento de pe?as estruturais de cor escura a vermelha, necessitando, pois, da mistura de uma argila menos pl?stica com granula??o grossa, que funciona como redutor de plasticidade. Apesar das diferentes formas de conforma??o por prensagem e extrus?o, as caracter?sticas de absor??o de ?gua e tens?o de ruptura a flex?o mostrou-se dentro dos padr?es da ABNT
