Process for making glazed ceramic ware

Claim 2

A process for making a glazed ceramic ware comprising the steps of: (a) mixing sufficient clay, feldspar, flux and water containing a deflocculant to form a slurry glaze-forming composition, said slurry composition consisting essentially of at least 30%, by weight, of clay, and where the molecular ratio of flux to alumina to silica in said slurry is from 1-0.1-1.15 to 1-1.05-9.2 and wherein said deflocculant is included with said water to minimize the amount of said water necessary to form said slurry; (b) applying the slurry onto the surface of an unfired clay body to form a decorative pattern; (c) firing the combined clay body and decorative pattern so that they are matured in one firing operation.

Claim 3

A process for making a glazed ceramic ware comprising the steps of: (a) mixing sufficient clay, feldspar, flux and water containing a deflocculant to form a slurry glaze-forming composition, said slurry composition consisting essentially of at least 30%, by weight, of clay, and where the molecular ratio of flux to alumina to silica in said slurry is from 1-0.1-1.15 to 1-1.05-9.2 and wherein said deflocculant is included with said water to minimize the amount of said water necessary to form said slurry; (b) placing the slurry on a porous surface in a decorative pattern; (c) allowing said decorative pattern to dry, applying the surface of a green clay ceramic body to said decorative pattern on said porous surface thereby transferring the decorative pattern to the surface of the green ceramic body; (d) firing the combined clay body and decorative pattern so that they are matured in one firing operation.

Claim 4

A process for making a glazed ceramic ware comprising the steps of: (a) mixing sufficient clay, feldspar, flux and water containing a deflocculant to form a slurry glaze-forming composition, said slurry composition consisting essentially of at least 30%, by weight, of clay, and where the molecular ratio of flux to alumina to silica in said slurry is from 1-0.1-1.15 to 1-1.05-9.2 and wherein said deflocculant is included with said water to minimize the amount of said water necessary to form said slurry; (b) placing the slurry on a porous surface in a decorative pattern; (c) allowing said decorative pattern to dry, applying the surface of a green clay ceramic body to said decorative pattern on said porous surface thereby transferring the decorative pattern to the surface of the green ceramic body; (d) firing the combined clay body and decorative pattern so that they are matured in one firing operation.

Claim 5

A process for making a glazed ceramic ware comprising the steps of: (a) mixing sufficient clay, feldspar, flux and water containing a deflocculant to form a slurry glaze-forming composition, said slurry composition consisting essentially of at least 30%, by weight, of clay, and where the molecular ratio of flux to alumina to silica in said slurry is from 1-0.1-1.15 to 1-1.05-9.2 and wherein said deflocculant is included with said water to minimize the amount of water necessary to form said slurry; (b) placing the slurry on a non-porous surface in a decorative pattern; (c) applying the surface of a porous body to the surface of the decorative pattern thereby transferring the decorative pattern to the surface of the porous body; (d) allowing said decorative pattern to dry, applying the surface of a green clay ceramic body to said decorative pattern on said porous surface thereby transferring the decorative pattern to the surface of the green ceramic body; and (e) firing the combined clay body and decorative pattern so that they are matured in one firing operation.

Claim 6

A process for making a glazed ceramic ware comprising the steps of: (a) mixing sufficient clay, feldspar, flux and water containing a deflocculant to form a slurry glaze-forming composition, said slurry composition consisting essentially of at least 30%, by weight, of clay, and where the molecular ratio of flux to alumina to silica in said slurry is from 1-0.1-1.15 to 1-1.05-9.2 and wherein said deflocculant is included with said water to minimize the amount of water necessary to form said slurry; (b) placing the slurry on a non-porous surface in a decorative pattern; (c) applying the surface of a porous body to the surface of the decorative pattern thereby transferring the decorative pattern to the surface of the porous body; (d) allowing said decorative pattern to dry, applying the surface of a green clay ceramic body to said decorative pattern on said porous surface thereby transferring the decorative pattern to the surface of the green ceramic body; and (e) firing the combined clay body and decorative pattern so that they are matured in one firing operation.

Claim 7

The process for making glazed ceramic ware according to claims 1, 2 or 3 wherein the deflocculant is present in said water in an amount between 0.01% and 1% by weight.

Claim 8

A process for making glazed ceramic ware according to claim 2 wherein various slurries of varying colors are applied to said non-porous body to produce a variously colored and highly decorative glazed ceramic body.

Claim 9

A process for making glazed ceramic ware according to claim 3 wherein said porous body is plaster of paris.

Claim 10

A process for making glazed ceramic ware according to claim 3 wherein said deflocculant is sodium silicate, calcium carbonate, or barium carbonate.

Claim 11

A process for making glazed ceramic ware according to claim 3 wherein various slurries of varying colors are applied to said non-porous body to produce a variously colored and highly decorative glazed ceramic body.
