In Juazeiro de Piauí and Castelo do Piauí, two cities in northeast Brazil, mined morisca rock is widely used in civil construction for external coating applications. Aiming at a sustainable practice for its extraction, which includes the economical use of the tailings from its mining, this work presents a solution for the use of discarded materials from processing morisca from Piauí. In this context, an analysis of the results of using morisca as a substitute for clay materials for applications in red ceramics are presented. For the analyses, XRF, XRD, microgranulometry, limits of consistency, TG, DTG, and a set of technological tests inherent to ceramic materials were used. It was concluded that morisca powder is viable as a clay substitute for red ceramic applications. Full article
