Abstract
Abstract A decalcomania having a non-wood derived paper backing and a method for incorporating the decalcomania design onto a ceramic substrate. The paper backing can be derived from seaweed. The decalcomania can be applied to greenware without removal of the paper backing. The method requires no heat treating or firing of the ceramic article prior to setting the decalcomania and requires only on firing step following setting of the decalcomania to accomplish glazing.

Claim 15
Dependent Claim
13 words
The decalcomania of claim 11 wherein said paper backing is derived from seaweed.
Claim 16
Independent Claim
76 words
A method for applying a design to non-fired ceramic greenware comprising applying a bonding medium to said greenware, setting a non-wood derived paper-backed decalcomania on said bonding medium without removing said paper backing, applying a glaze over said decalcomania and firing said greenware at a temperature sufficient to both mature the glaze and form a bisque and wherein said non-wood derived paper is of a type which decomposes and gasifies at temperatures below said firing temperature.
Claim 17
Independent Claim
76 words
A method for applying a design to non-fired ceramic greenware comprising applying a bonding medium to said greenware, setting a non-wood derived paper-backed decalcomania on said bonding medium without removing said paper backing, applying a glaze over said decalcomania and firing said greenware at a temperature sufficient to both mature the glaze and form a bisque and wherein said non-wood derived paper is of a type which decomposes and gasifies at temperatures below said firing temperature.
Claim 18
Dependent Claim

Claim 20
Dependent Claim
20 words
The method of claim 13 wherein said firing step is the only firing step to which said greenware is subjected.
Claim 21
Independent Claim
113 words
A method for applying a design to non-fired ceramic greenware comprising applying to said greenware a bonding medium comprising flux suspended in a bonding organic vehicle, setting on said bonding medium, a decalcomania comprising decalcomania flux and pigment suspended in a decalcomania organic vehicle and supported on a non-wood derived paper backing, said paper backing being porous and migration of bonding organic vehicle occurring through said pores, drying said decalcomania near room temperature, applying a glaze over said decalcomania and firing said greenware at a temperature sufficient to both mature the glaze and form a bisque, said paper being of a type which decomposes and gasifies at a temperature below said firing temperature.
Claim 22
Independent Claim
113 words
A method for applying a design to non-fired ceramic greenware comprising applying to said greenware a bonding medium comprising flux suspended in a bonding organic vehicle, setting on said bonding medium, a decalcomania comprising decalcomania flux and pigment suspended in a decalcomania organic vehicle and supported on a non-wood derived paper backing, said paper backing being porous and migration of bonding organic vehicle occurring through said pores, drying said decalcomania near room temperature, applying a glaze over said decalcomania and firing said greenware at a temperature sufficient to both mature the glaze and form a bisque, said paper being of a type which decomposes and gasifies at a temperature below said firing temperature.
