The comparison between red ceramic pieces with and without incorporation of ornamental rock residue was evaluated in this work through wetting and drying cycles in up to 175 cycles. The firing temperatures used were up to 950ºC and the residue incorporations were up to 10% (0R, 5R and 10R). The greatest aging observed was for ceramic samples without residue, which characterizes increased durability. The index of loss of flexural strength was higher for samples 0R than for 5R, that is, 59.8% and 39.19% respectively. This is due to the presence of microcline, anortite and biotite in the stone residue, which forms molten flux a liquid phase in sintering.
