1. A method of plugging a honeycomb body, the method comprising the steps:
contacting a first end of the honeycomb body comprising a plurality of channels with a light curable sealing mixture disposed in a light transparent container such that an infiltrate of the light curable sealing mixture flows into the plurality of channels proximate the first end;
emitting a light directed at the first end of the honeycomb body to expose a first portion of the infiltrate within the plurality channels to the light, wherein the light is emitted from a light source which is positioned such that the light passes through the container prior to reaching the honeycomb body; and
curing the first portion of the infiltrate within the channels with the light to form a plurality of seals.
