DETAILED DESCRIPTION OF THE INVENTION

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the attached figures illustrate a ceramic bisque product with underglaze outlines, which comprises pieces of ceramic bisque that have been enhanced with underglaze outlines designed by professional artists with years of experience and training who understand the medium. The artists' designs are then painted onto bisque items in the form of basic outlines using underglaze ceramic paints. The bisque pieces are again fired in a kiln causing the painted outlines to become one with the original bisque piece. To produce a professional looking ceramic art piece, the consumer need only paint between the lines. Unlike “paint-by-numbers” techniques used previously on canvas painting projects, the underglaze outlines are not covered up and become an integral part of the finished piece. The initial component is a molded or pressed clay object that has been hardened by kiln firing into what is known as “bisque.” Bisque pieces are enhanced in this invention by the addition of professionally designed underglaze outlines. The outline enhanced bisque piece is then subjected to a second kiln firing that causes the outline to become one with the original piece. The end result is an underglaze outline that is not covered up but rather is an integral part of the finished piece.

The initial component is a molded or pressed clay object that has been hardened by kiln firing into what is known as “bisque.” Bisque is a molded or pressed piece of clay having been hardened by kiln firing. Bisque is commonly available in a variety of shapes and sizes including functional items such as plates, mugs, clock and pictures frames to non-functional decorative items.

Bisque pieces are enhanced in this invention by the addition of professionally designed underglaze outlines. Underglaze outlines are painted onto bisque items. Underglaze outlines are designed by talented artists with years of training and experience that are an integral part of the finished project.

The outline enhanced bisque piece is then subjected a second kiln firing that causes the outline to become one with the original piece. Underglaze outlines become a permanent part of the original bisque piece which results in new product substantially different from the original art. The designs will not wash off and will show through later design efforts by the consumer.

The end result is an underglaze outline that is not covered up but rather an integral part of the finished piece. The end result is a professional looking decorated piece of art. The underglaze outlines become a bold and integral part of the finished piece and the primary focus of an observer causing added decorations by the consumer to become secondary.

Professional designs are painted in outline form onto ceramic bisque, exposed to a second kiln firing so as to cause the outlines to become one with the original bisque piece. Outlines may vary in thickness and color. Underglaze products may be applied by brush, spray or other methods.

Bisque, molded or pressed pieces of clay, are hardened by kiln firing. Ceramic underglazes are added to the piece in the form of outlines. Bisque pieces are subject to a second kiln firing causing them to become one with the original object. The outlines are decorated and not covered and become an integral part of the finished project.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further; since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.

A method for preparing a molded clay object for receiving decorative indicia is provided.

In one embodiment, as shown in FIGS. 1A and 1B, a blank molded clay object 10, 11 is selected for decoration. The molded clay object 10, 11 has been hardened by kiln firing into what is known as bisque. Bisque is commonly available in a variety of shapes and sizes including plates, mugs, clock, pictures, figurines and other decorative items.

An artist designs decorative indicia to be applied to the molded clay object. Ceramic paint is applied to the molded clay object with an applicator to trace a complete outline of the decorative indicia 20 and 21, as shown in FIGS. 2A and 2B, respectively. In one embodiment, the ceramic paint may be composed of a medium including crushed glass, in addition to other products. The decorative indicia 20 and 21 are only representative of decorative indicia that may be used. Decorative indicia of any shape may be used in the present invention. The ceramic paint may be applied by brush, spray, screenprinting, or other methods.

After the ceramic paint is applied, the molded clay object 10, 11 is fired and cooled to room temperature in a kiln, permanently fixing the decorative indicia 20, 21 in a traced outline on the object. The decorative indicia 20, 21 will not wash off and will show through later decoration.

Once the molded clay object 10, 11 is removed from the kiln, it may be decorated by a consumer. The consumer applies ceramic paint to the curved molded clay object in the spaces within regions 30, 31 indicated by the decorative indicia 20, 21, as shown in FIGS. 3A and 3B. The molded clay object 10, 11 is thereafter coated with a glaze. The glazed molded clay object 10, 11 is then fired a second time and cooled to room temperature in a kiln to fix the ceramic paint in a permanent state and create a wear-resistant coating. The decorative indicia outline 20, 21 remain visible in the finished piece.

In another embodiment, the decorative indicia is applied to molded clay object by a screen printing process. The screen printing process may be used to apply the decorative indicia 21 to a flat molded clay object 11. In the screen printing process, ceramic paint is applied to a screen with perforations having an outline of the decorative indicia 21. The flat molded clay object 11 is placed under the screen. An applicator is used to press the ceramic paint through the perforations in the screen to deposit the ceramic paint onto the flat molded clay object 11.

The flat molded clay object 11 is then fired and allowed to cool in a kiln to permanently fix the decorative indicia.

Once the flat molded clay object 11 is removed from the kiln, it may be decorated by a consumer. The consumer applies ceramic paint to the flat molded clay object 11 within regions 31 indicated by the decorative indicia 21, as shown in FIG. 3B. The colored and decorated flat molded clay object 11 is thereafter coated with a glaze. The flat molded clay object 11 is fired and cooled to room temperature in a kiln to fix the ceramic paint in a permanent state and create a wear-resistant coating. The outlines remain visible in the finished piece.

In another embodiment, the decorative indicia is applied to the molded clay object using a transfer process, as shown in FIGS. 4A, 4B, 4C and 4D. The transfer process may be used to apply the decorative indicia 20 to a curved molded clay object 10. A sheet of transfer paper 40, as shown in FIG. 4A, is placed under a screen 48, as shown in FIG. 4B. In the transfer process, ceramic paint is applied to the screen 48 with perforations 47 having an outline of the decorative indicia 20. An applicator 49 is used to press the ceramic paint through the perforations 47 in the screen 48 to deposit the ceramic paint onto the sheet of transfer paper 40 in an outline of the decorative indicia 41. The ceramic paint is transferred to the curved molded clay object 10 by smoothing the side of the sheet of transfer paper 40 with the ceramic paint onto the curved molded clay object 10, as shown by arrows 42 in FIG. 4D. The sheet of transfer paper 40 is removed after a few seconds have passed to allow the ceramic paint to be absorbed into the curved molded clay object 10.

For some decorative indicia, such as large decorative indicia or decorative indicia for multiple surfaces, the transfer process may be repeated with one or more screens. Ceramic paint is applied to the screen previously used or a new screen and an applicator is used to press the ceramic paint through the perforations in the screen onto another sheet of transfer paper. The ceramic paint is transferred to the curved molded clay object 10 by smoothing the side of the transfer paper with the ceramic paint onto the curved molded clay object 10 and the transfer paper is removed after a few seconds. This transfer process may be repeated until all of the desired decorative indicia have been applied to the curved molded clay object 10.

The curved molded clay object 10 is then fired and allowed to cool in a kiln to permanently fix the decorative indicia.

Once the curved molded clay object 10 is removed from the kiln, it may be decorated by a consumer. The consumer applies ceramic paint to the curved molded clay object 10 within regions 30 indicated by the decorative indicia 20, as shown in FIG. 3A. The colored and decorated curved molded clay object 10 is thereafter coated with a glaze. The curved molded clay object 10 is fired and cooled to room temperature in a kiln to fix the ceramic paint in a permanent state and create a wear-resistant coating. The outlines remain visible in the finished piece.

In another embodiment, the ceramic paint used to outline the decorative indicia is a single color.

In another embodiment, the ceramic paint used to outline the decorative indicia is a slow-drying formulation.

In another embodiment, the molded clay object 10, 11 is coated with an acrylic coating after the decorative indicia 20, 21 have been applied and it has been fired and removed from the kiln. Now the consumer may apply indelible ink, such as markings from permanent markers, to the molded clay object 10, 11 within regions 30, 31 indicated by the decorative indicia 20, 21. There is no need for adding a glaze or kiln firing after the indelible ink has been applied to a molded clay object 10, 11 that has an acrylic coating. The indelible ink is permanently fixed to the acrylic coating upon application.

The present invention has been described in preferred and exemplary embodiments and aspects, but is not limited thereto. Persons skilled in the art will appreciate that other modifications and applications can be made without meaningfully departing from the invention. Accordingly, the foregoing description should not be read as limited to the precise embodiments and aspects described, but should be read consistent with and as support for the following claims, which are to have their fullest and fairest scope.
