A process for preparing a porous ceramic body in which a green body containing at least 60 weight percent of ceramic material, at least about 25 weight percent of water, and from 5 to 40 weight percent of gluten is formed. The green body is dried until it contains less than about 0.5 weight percent, and it is then heated to a temperature of from 1,100 to 3,200 degrees Fahrenheit until substantially all of the gluten has been removed. |
