Abstract
Methods of firing ceramic honeycomb bodies are disclosed that include heating the ceramic honeycomb bodies and blocking furnace gases from flowing through the ceramic honeycomb body by placing an aluminum metal layer adjacent an endface of the honeycomb body. Heating removes organic pore-forming material and graphite pore-forming material in the ceramic honeycomb body. The aluminum metal layer oxidizes to form a porous Al2O3 layer after firing to a first temperature, and furnace gases flow through the ceramic honeycomb body.
