ABSTRACT:
A method of plugging the ends of selected ducts (5) in a ceramic structure (1). A paste (8, 9) is prepared from a powder and a liquid. The powder comprises a glass whose coefficient of expansion is close to that of the ceramic structure. The liquid comprises a solvent, a plasticizer and an additive which reduces the adherence of the paste to a paste applying tool (6, 7). The tool is used to push paste into the ends of the selected ducts and the ceramic structure is subjected to heat treatment to ensure that the paste adheres to the walls of the ducts and then becomes solid.
