Abstract
A method of decorating a surface of a ceramic body in which a thin uniform film of colorant composition material is carried by a decorating member in a suspended state across an opening of selected area and shape corresponding to the designs to be applied to the surface of said body, the colorant material being deposited thereon by breaking the surface tension of the suspended film by contact with said surface. An apparatus for decorating a surface of a ceramic body including a receptacle for the colorant composition material, decorating members for holding one or more films of colorant composition material in a suspended state across openings configured to the shape of the design to be applied to the ceramic body; said decorating members being movable to immerse said decorating members in said colorant composition material and to deposit under gravitational forces said film on said surface.
