Claim 0:
1. 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 the first viscosity is within a range of from about 25,000 cP to 400,000 cP and the second viscosity is about 15,000 cP or less.
