Abstract
An unfired recycled material recovered in the course of the production of a cordierite ceramic body is comminuted to prepare a comminuted material. The comminuted material is then subjected to size separation to remove fine particles with diameters of less than 1 mm from the comminuted material while retaining coarse particles with diameters of not less than 1 mm. Water is added to the comminuted material with particle diameters of not less than 1 mm, and the mixture is kneaded to prepare a reprocessed clay. The reprocessed clay is formed into a shape which is then fired to prepare a cordierite ceramic body.
