After treatment with milk, wine, urine and different phosphate solutions, all the studied ceramics have shown an important phosphorus uptake. The quantity of phosphorus fixed by ceramics depends on the interaction of ceramic characteristics (mineralogical nature, firing temperature, presence or not of calcite) with the pH and the phosphate concentration of burial or use media. The observed phosphorus uptake is best marked where clays are less fired, where they are calcareous, where the time of contact with the medium and its temperature increase. The optimal fixation occurs in slightly acidic medium, less acidic for the calcareous ceramics than for the non-calcareous ones.Après immersion dans le lait, le vin, l'urine et des solutions phosph...
