ABSTRACT:
A process for the functional regeneration of the porosity of the materials used to make molds (2) for moulding ceramic objects, when the pores have been damaged by use of the mold (2), comprises the sequential execution of at least two successive steps of an ordered sequence which includes the steps of: eliminating contamination caused by organic substances form the mold (2); eliminating contamination of biological origin from the mold (2); attacking inorganic encrustations and eliminating inorganic substances which have infiltrated the pores of the mold (2), the initial step of the process being preset according to the nature of a predetermined contaminating agent. A station implementing the process is also an integral part of the present invention.
