The aim is to show the intervention of restoration and preventive conservation for the stabilisation of the saponified textile materials from grave 111 of the cemetery of the town of Paterna (València). Body saponification by hydrolysis has allowed excellent conservation for more than 80 years of the clothes and other elements of the reprisals within the pit itself. When these materials come into contact with oxygen during exhumation, they cause a rapid putrefaction of the biological film that endangers the stability of the tissue. The work has consisted of carrying out the necessary technical processes to eliminate this biological film and stabilise the pieces for their patrimonialisation, later, they have been adapted for their definitive conservation in the reserve room.
