The results of research on the use of sludge produced in the process of purification of drinking water (SPDW), which contains about 68% Fe 2 O 3 , as an additive in the production effective ceramic articles are presented. SPDW was added in amounts 40 – 60% into the batch for the production of effective ceramic articles; the firing temperature of the ceramic articles was 900, 1000, and 1050°C. The investigations showed that the addition of SPDW affects the properties of ceramic samples as follows: it lowers the density, strength in compression, and thermal conductivity and increases porosity. SPDW is a natural pigment that imparts a darker red color to the ceramic.
