Abstract
A method of manufacturing a particulate filter includes plugging at least some of the channels of a green cellular ceramic body on a first end with a green plugging material that includes a liquid vehicle to form a partially plugged green cellular ceramic body, firing the partially plugged green cellular ceramic body to form a partially plugged ceramic article, and plugging at least some of the channels on a second end of the partially plugged ceramic article with a plugging material that sets at a temperature of less than 1000° C.
