Patent ID: 8568649

Claim:
A method of preparing a ceramic article precursor by the sequential alternative application of layers of material as follows: (a) a layer of a ceramic precursor powder comprising; (i) from about 50% to about 80% clay; (ii) from about 5% to about 20% feldspar; (iii) from about 2% to about 10% refractory cement; (iv) from about 2% to about 10% frit; and (v) from about 0.5% to about 4% sodium silicate; and (b) a layer of an aqueous liquid binder solution having at least one water-soluble binder dissolved in water; so as to form a sequential material layer having an original thickness; and (c) compressing each sequential material layer so as to reduce said original thickness thereof, prior to the deposition of any subsequent sequential material layer; so as to form a ceramic precursor article.
