<p>A method of manufacturing a porous ceramic article is provided that includes injecting a gas into a precursor batch material. The gas is pressurized to a positive gauge pressure. Exemplary gasses that can be injected into the precursor batch material include at least one of nitrogen, helium, neon, argon, krypton, and xenon. Air can also be injected into the precursor batch material, including air in which at least a portion of CO2 and/or O2 naturally occurring in air has been removed.</p> |
