Abstract
A clay-pulp mixture is prepared by blending a predetermined ratio of clay and wood pulp (specifically, fiber derived from virgin alpha cellulose) in dry form, moistening the mixture homogeneously by adding water and continuing to blend until a malleable consistency is achieved. Air is extracted from the moist mixture, and solid blocks formed for storage and delivery to end-users.
