Abstract
A method of manufacturing porous ceramic articles is provided that includes forming a plurality of extruded green bodies from a ceramic precursor batch composition. The method also includes firing the extruded green bodies in a tunnel kiln to produce porous ceramic articles, periodically determining a shrinkage characteristic of at least one sample passing through the tunnel kiln, and adjusting a top soak temperature in the kiln if the shrinkage characteristic is outside of a predetermined range.
