This work aims to incorporate gems waste (sludge saw cutting of gems), produced in an amethyst and agate firm cut, in the red ceramic body used for the production of solid bricks. The raw materials were tested by X-ray fluorescence, X-ray diffraction and granulometric distribution analysis, for characterize the mineralogy and physical chemistry of materials. Samples were prepared with 0%, 5%, 9%, 13% and 17% waste added to the ceramic body by mass. The physical properties studied were compressive strength, linear shrinkage, water absorption and density in accordance with current technical standard. The results showed that it is possible to incorporate up to 5% of waste in bulk ceramics.
