Abstract
Abstract Ceramic color compositions which are moisture or steam settable are described. The compositions are formulated from a dispersion of ceramic pigments or glass colors in certain moisture or steam set type vehicles and can be applied to green or bisque ceramic ware using standard decorating techniques and then set to a coating by exposure to moisture or steam. Over-glazing of the coating provides decoratively glazed ware of excellent quality and durability.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
A ceramic color composition comprising an intimate dispersion of from about 1 to about 6 parts of a ceramic pigment or a glass color in 1 part of a moisture or steam settable, liquid vehicle consisting essentially of a solution of at least one water-insoluble film-forming resin in a water-miscible solvent therefor, said vehicle being volatilizable without leaving objectionable residue thereof at a temperature below the decomposition temperature of the ceramic pigment and below the fusion temperature of the glass color, and the amount of resin in said vehicle ranging from about 15 to about 60% of the weight of said vehicle and being such that when the composition is applied to non-glazed ceramic ware and exposed to moisture or steam, a film of the resin is precipitated from the solvent onto the ware.
Claim 2
Dependent Claim
134 words
A ceramic color composition comprising an intimate dispersion of from about 1 to about 6 parts of a ceramic pigment or a glass color in 1 part of a moisture or steam settable, liquid vehicle consisting essentially of a solution of at least one water-insoluble film-forming resin in a water-miscible solvent therefor, said vehicle being volatilizable without leaving objectionable residue thereof at a temperature below the decomposition temperature of the ceramic pigment and below the fusion temperature of the glass color, and the amount of resin in said vehicle ranging from about 15 to about 60% of the weight of said vehicle and being such that when the composition is applied to non-glazed ceramic ware and exposed to moisture or steam, a film of the resin is precipitated from the solvent onto the ware.
Claim 3
Dependent Claim
30 words
The composition of claim 1 wherein the film-forming resin is a rosin ester having an acid number of at least about 50 and the solvent comprises at least one glycol.
Claim 4
Dependent Claim
13 words
The composition of claim 2 wherein at least one glycol is ethylene glycol.
Claim 5
Dependent Claim
24 words
The composition of claim 1 wherein the film-forming resin is a petroleum hydrocarbon-insoluble resin derived from wood rosin and the solvent is ethylene glycol.
