The object of investigation is the ceramic material taken from the fortress wall in the city of Girona. The chemical composition of the researched material showed a heightened content of carbon (13.1%) in it, attesting the introduction of fuel into the green body. The heightened content of fuel in the green body promotes porosity formation and uniform sintering inside the ceramic sample. The integral and differential programs of the research samples, which were obtained by means of mercury porosimetry, showed that the total volume of the micropores ranging in size from 10 – 4 to 10 – 8 m is equal to 0.155 cm3/g. The differential distribution of micropores as a function of their size is: 10 – 4 – 10– 5 — 27% (reserve – non-hazardous); 10 – 5 – 10– 6m— 19% (hazardous); 10 – 6 – 10– 7 m — 29%; 10 – 7 – 10– 8 m — 25% (non-hazardous).
