Claim 18:
19. A method of plugging channels of a honeycomb body comprising a plurality of channels, the method comprising:
applying a shear force to a plugging mixture to alter the viscosity of the plugging mixture from a first viscosity prior to the applying the shear force to a second viscosity which is less than the first viscosity, wherein the plugging mixture comprises a plurality of inorganic particles, clay, and a liquid vehicle;
placing a honeycomb body into contact with the plugging mixture such that a portion of the plugging mixture having the second viscosity flows into the plurality of channels;
reducing or stopping application of the shear force to increase the viscosity of the portion of the plugging mixture in the plurality of channels to greater than the first viscosity; and then
removing the honeycomb body, along with the portion of the plugging mixture that flowed into the plurality of channels, from contact with a remaining portion of the plugging mixture;
wherein applying the shear force to the plugging mixture comprises vibrating the plugging mixture, and
wherein the plugging mixture is vibrated along at least two axes during the placing of the honeycomb body into contact with the plugging mixture.
