Description

MEDALLION WITH DECORATED SUBSTRATE CARRIED THEREON

BACKGROUND OF THE INVENTION

1. Field of the Invention:

The present invention relates generally to commemorative coins and medallions. More specifically, the present invention relates to embedding commemorative coins and medallions with substrates for various purposes.

2. Discussion of Background:

Non-monetary coins and medallions are made for a variety of purposes, including commemorating events or special occasions. These items are examples of medallic art, which are decorations worked in relief; that is, the images on them are formed by removing or redistributing a small amount of material, leaving a three-dimensional, contoured surface.

The subjects for medallic art can sometimes be taken from two- dimensional, full color artwork. Translating the two-dimensional, colorful artwork to either high or low relief in metal is in itself an art. Furthermore, the commemorative coin or medallion is usually smaller than the original two-dimensional work. The difference in medium and in size inevitably means a loss of detail and color. Inevitably, the artists are not pleased with the result, regardless of the skill of the sculptor.

There is a technique for making a replica of two-dimensional, full color artwork in the form of a decal that can be fired onto a porcelain surface. This technique has been used to decorate coffee mugs and tiles. It is also known to apply procelain to metal.

The method described in US 5,698,287 issued to the present inventor is also relevant to the subject of making commemorative medallions and keepsakes having artwork embedded within a metal anaglyph.

SUMMARY OF THE INVENTION

According to its major aspects and briefly stated, the present invention is the embedding of two or three-dimensional artwork applied to a wafer, carrying a full-color, miniature reproduction of two-dimensional artwork, onto an anaglyph medallic piece of art, such as a commemorative coin or medallion. The medallic art is formed by striking, molding, cold casting, hot casting, and by the well known "lost wax" method. In the case of a ceramic wafer, the artwork is applied to the porcelain wafer by hand painting or by creating a decal that is a four-color, miniature version of the full-sized, two-dimensional artwork and then firing the decal onto the surface of the wafer. The medallic art can be made of metal, plastic, wood, porcelain, or other ceramic. The medallic art's design preferably corresponds to the reproduction in its ornamentation and text, and embedding protects the wafer. The medallion can then be embedded in clear plastic, mounted in a frame, encased in a display cabinet, or set into a ring connected to a key chain.

The use of four-color reproduction, in miniature, is an important feature of the present invention, because the resulting commemorative coin or medallion will contain a much more acceptable likeness of the original art. In an alternative embodiment, the use of hand-painting of a ceramic or enameled wafer by an artist may may limited edition works more valuable.

The medallic art with a depression formed therein for embedding the wafer is another important feature of the present invention. The medallic art not only can complement the artwork, but it can also protect it, especially when the wafer is made of porcelain and the medallic art is made of metal.

The embedding of a miniature reproduction of art in a commemorative coin or medallion is another feature of the present invention because it adds color and detail to the article.

The use of the technique of firing a decal onto porcelain in combination with the commemorative coin or medallion is still another feature of the present invention. This technique allows all of the color and detail to be reproduced, even in miniature, and does so in a way that will last with minimal fading.

Other features and advantages will be apparent to those skilled in the art from a careful reading of the detailed description of a preferred embodiment accompanied by the following drawings.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

In its preferred embodiment, the present invention is the embedding of a four-color, miniature reproduction of two-dimensional artwork carried by a ceramic substrate into a commemorative coin or medallion. More generally, however, the present invention is a two or three dimensional artwork applied to a ceramic or metal wafer that is adhered within a recess formed in a substrate made of ceramic or metal and which carries its own ornamentation the corresponds in some way to that on the wafer. Clearly, if the original art is small enough, it may not have to be reduced in size. Furthermore, if the original art is a pen and ink drawing, having no color, the present technique will nonetheless still apply. Finally, it will be clear that, rather than using a ceramic or metal wafer to carry the artwork, a small glass or transparent plastic wafer can be placed over artwork that has been placed in a depression formed in the medallic art. The medallion can then be packaged or encased in a shippable container, preferably one that can be used for display. The medallion can be displayed by embedding in clear plastic, mounting it in a frame, encasing it in a display cabinet, or setting into a ring connected to a key chain.

Reference is now made to Figs.1 and 2, which show an exploded perspective view and a cross sectional side view of the article, respectively, generally indicated by reference numeral 10. Article 10 comprises a medallic artwork 20 in the form of a coin or medallion and a substrate 30. Medallic artwork 20 has a front face 40 and a rear face 50 which can be contoured to create any decorative appearance desired by an artist. Formed along front face 40 of medallic artwork 20 is a recess or depression 60, dimensioned to receive substrate 30. Preferably, substrate 30 is also thinner than depression 60 is deep so that substrate 30 is protected by front face 40 of artwork 20. The shape of surface of depression 60 preferably corresponds to the shape of substrate 30 ~ if substrate 30 is convex, then depression 60 should be convex, for example — and most preferably — depression 60 is smooth and flat. Medallic artwork 20 can be made of any metal or metal alloy which has the requisite strength and malleability required of the particular application or of porcelain or other ceramic. Examples of suitable metals for medallic artwork are gold, gold alloys, silver, copper, bronze, aluminum, and pewter. Also, it will be appreciated that although illustrated in the figures as a disk, medallic artwork 20 may be formed to assume any desired shape.

Preferably, substrate 30 is made of any sintered ceramic material, metal, bone, wood, paper or other surface on which an art reproduction can be applied. Most preferably, given considerations of cost, durability and aesthetic characteristics, substrate 30 is vitrified porcelain. Substrate 30 is vitrified in accordance with well-known ceramic processing procedures. Substrate 30 may be decorated by painting, carving, etching or any other decorative technique. In one embodiment, front face 70 of substrate 30 has fired thereon a miniaturized reproduction of a two-dimensional art work. The method used to impart the replica of art onto front face 70 of substrate 30 may be any method commonly employed by those skilled in the ceramic arts that is capable of accurate reproduction. Most preferably, the method is one that lends itself to exact, repeatable, four-color reproduction rather than, for example, hand painting, which is not accurately repeatable. For illustrative purposes, a method for replicating a two-dimensional piece of art onto substrate 30 may be as follows: A two-dimensional artwork, such as a painting, is scanned into a laser scanner having high color resolution. The scanner is in operational connection with a printer equipped to print the scanned image onto decal paper suitable for application to ceramics. This decal paper is impregnated with a glue or adhesive to prevent the migration of pigments imprinted by the printer. The imprinted decal is then covered with clear lacquer and allowed to dry. Thereafter, the lacquered decal is submerged in water, which serves to separate the paper from the lacquered pigment. The lacquered pigment is then placed over front face 70 of substrate 30 and fired. This method serves to produce four- color, high-resolution, miniaturized reproductions of two-dimensional art work onto substrate 30.

Substrate 30 is adhered to medallic artwork 20 by placing a layer of adhesive onto rear face 75 of substrate 30 and thereafter placing substrate 30 within depression 60. The type of adhesive used will depend upon the choice of materials for medallic artwork 20 and substrate 30 and is within the purview of an artisan with ordinary skill in the art; however, silica- based adhesives are preferred.

Turning now to Fig. 3, there is shown a cross sectional side view of an alternative embodiment of the present invention, generally designated by reference numeral 100. Article 100 comprises an medallic artwork 110 and two substrates 120. Formed in first face 130 and second face 140 of medallic artwork 110 are recesses 150 dimensioned to receive substrates 120. Turning now to Fig. 4, there is shown a flow chart depicting a method for forming an article according to a preferred embodiment of the present invention. The method first involves creating a decal from a two- dimensional artwork. This can be accomplished by using any known technique able to replicate the art in a four-color printing. Thereafter, a sintered substrate is manufactured. The decal of the artwork is then fired into the substrate using standard ceramic glazing procedures. Meanwhile, the anaglyph medallic artwork is manufactured with a low or high relief, sculpted surface and a recess for receipt of the substrate. The manufacture of the medallic artwork may be done manually or in accordance with procedures known to the art of metal working. Such procedures include, but are not limited to, striking, cold casting, hot casting, molding, and the lost wax method. The decorated substrate is then attached within the depression in the medallic artwork using a suitable adhesive.

The foregoing article and method serves to produce a collectable piece having a sculpted surface carrying thereon a miniaturized replica of a two- dimensional artwork. The article can be manufactured with any design in any format desired by the artist. Such formats include, but are not limited to, medallions and commemorative coins. Preferably, the design on the medallic artwork is made to correspond to the artwork. For example, if the artwork is of wildlife, the medallic artwork may include text and artwork that identify the wildlife and depict flora characteristic of the wildlife habitat, or it could repeat in three dimensions a portion of the two- dimensional art.

In works requiring a smaller production rate, the wafer can be hand painted or decorated in some other way before insertion into a recess in a medallic work. Hand decorating may result in each work being slightly different, normally a drawback, but if the decoration is applied by an artist, may make each piece more valuable.

The artwork can be applied to a metal or metal alloy wafer and set within a recess formed in a substrate made of ceramic, metal or metal alloy. As examples, an enameled metal wafer can be set within a bronze medallion, a die-stamped gold wafer can be set into a silver medallion. A die-stamped or painted metal campaign button can be placed into a recess in a plastic medallion with a key chain attached. It is important that the wafer contain art that corresponds to the art or text on the medallion holding it and that the wafer be received into a recess formed in the medallion.

It will be apparent to those skilled in the art that many modifications and substitutions can be made to the preferred embodiment just described without departing from the spirit and scope of the invention as defined in the appended claims.
