The present invention generally relates to textured impressions for jewelry components; more particularly, the present invention relates to purpose-designed, pre-formed and shape-specific textured impressions for making jewelry components.
In recent years, both hobbyist and professional jewelry makers have utilized a variety of products, including polymer and metal clays, as a medium for jewelry designs that are readily available and require much less training and investment than conventional bench jewelry making. These materials are relatively soft and malleable; may be easily shaped into a desired form; and may be imparted with a unique and custom appearance by pressing any object (e.g., cookie cutters, coins, stencils, buttons, etc.) with a desired surface texture (e.g., a leaf, rock, wood, burlap clothe, pasta) into the material.
Various textures have become available that offer unique appearance as well as consistency and the ability to be used more than once. These textures may be made in a rubber stamp, metal plate or mold to impart the appearance to the clay. Current textures are typically oversized in a square or rectangular sheet with a repeating pattern.
A limitation of the use of current textures is that patterns, textures and designs imparted a the raw-shaped piece are not shape-specific and, therefore, do not follow or conform to the geometry of the final jewelry piece, resulting in an abstract look as opposed to an integral and professional look. For example, with reference to
Because of the non-shape specific nature of current textures, use of textures makes it difficult to achieve a consistent design throughout all of the components of the final jewelry piece. Additionally, with current textures, edges are not predefined, and final jewelry pieces might not have a professional, jewelry-quality appearance. Further, in cases where consistency in shape and design from one jewelry piece to another is important, given that various portions of the final jewelry piece are made using different textures, formation of the final jewelry piece might require assembly of the individual portions, which might lead to one final jewelry piece being significantly different from another.
Accordingly, there is a need in the art for methods and impressions that are capable of creating jewelry pieces in fewer processing steps than current methods.
The present invention can be used to impart a purpose-designed, specific shape and integral design to any soft and malleable substrate that must resultingly be fired or cured to proper hardness and final form, including precious metal clay, art clay, polymer clay, organic materials, plastics, glass clay, polymer clay, resin, powdered metal or glass, or other clay or malleable materials.
The artist can design jewelry article using manual or computer means. The design will include all of the purpose-designed shapes, integral design textures and borders necessary to convey the desired them and vision. The artists desired negative images are then reproduced on a medium that is selectively etched to form a positive image suitable for the transfer to the various mediums selected by jewelry artists.
In an aspect of the invention, a textured impression for producing components used in jewelry making is provided, comprising a geometric shape for a specific component of an end-item jewelry piece; a texture or design that specifically follows the geometric shape; and a means for applying the impression of specific shape and integral texture into a desired medium.
In another aspect of the invention, a purpose-designed template for forming a jewelry piece is provided, the purpose-designed template comprising a first design that is an inverse image of a second design substantially defining the jewelry piece, the purpose-designed template configured to form the second design in a clay material.
In yet another aspect of the invention, a method for forming a jewelry piece is provided, comprising pressing a clay material having one or more metals onto a template, the template having a first design, wherein pressing the clay material onto the template forms a second design in the clay material, the second design being a negative image of the first design; removing the clay material from the template; and annealing the clay material.
In still another aspect of the invention, a method for forming a template for use in producing a jewelry piece is provided, comprising forming a master template, the master template formed from a metallic material, the master template having a design that is an inverse of or that substantially matches a design of the jewelry piece; and forming a matrix template from the master template, the matrix template formed from a polymeric material, the matrix template having a design that is an inverse of the design of master template.

In an embodiment, a method for forming a metallic jewelry piece is provided. The method comprises pressing a clay material having one or more metals onto a template (or master template), the template having a first design, wherein pressing the clay material onto the template forms a second design in the clay material, the second design being a negative image of the first design. In an embodiment, the clay material is pressed onto the template with the aid of a user's hand pressure. In another embodiment, the clay material is pressed onto the template with the aid of a mechanical device, such as a roller or a press. Next, the clay material is removed from the template. The clay material is then dried and annealed. In an embodiment, the clay material is dried at room temperature before annealing. In an embodiment, the clay material is annealed at a temperature sufficient to remove any solvent (and other non-metallic substances) from the clay material. In an embodiment, the annealing temperature is selected based on the clay material used to form the jewelry piece. In embodiments, the annealing temperature is between about 225° C. and 2800° C. For polymer clays, the annealing temperature can be between about 225° C. and 350° C., and the annealing time can be between about 30 minutes and 2 hours. For metal or ceramic clays (i.e., clay materials comprising metal or ceramic components), the annealing temperature can be between about 700° C. and 2800° C., and the annealing time can be between about 30 minutes and 22 hours. In some embodiments, the clay material can be air dried at room temperature.
In an alternative embodiment, the method described above can be used to form a non-metallic jewelry item, such as a glass jewelry item. The clay material having the second design is annealed to form a second template having one or more metals (e.g., Ag). While the metallic piece can serve as the jewelry item in certain embodiments, in this alternative embodiment the metallic piece will serve as another (second) template. The second template comprises the second design that is an inverse image of the first design. The second template can then be used to imprint the second design in molten glass, the molten glass comprising SiOx, wherein ‘x’ is a number greater than or equal to 1. This forms an inverse image of the second design in the molten glass. In an embodiment, the second template is brought in contact with molten glass to form a third design in the molten glass, the third design being an inverse image of the second design. The third design is substantially similar to the first design of the template. Next, the molten glass is cooled to form the jewelry piece.
In embodiments, the clay material comprises one or more metals selected from the group consisting of silver, platinum, gold, copper, titanium, bronze, magnesium and titanium. In an embodiment, the clay material comprises silver.
As yet another alternative, the template having the first design can be brought in contact with molten glass to form a fourth design in the molten glass, the fourth design being an inverse image of the first design. The molten glass can then be cooled to form a jewelry piece having the fourth design.
In another aspect of the invention, a method for forming a template for use in producing a jewelry piece is provided. The method comprises forming a master template, the master template formed from a metallic material. In an embodiment, the master template has a design that is an inverse (or negative image) of the jewelry piece. In another embodiment, the master template has a design that substantially matches a design of the jewelry piece. Next, a matrix template is formed from the master template. In an embodiment, the matrix template is formed from a polymeric material. The matrix template includes a design that is an inverse (or negative image) of the design of master template. In an embodiment, the matrix template defines the template for use in producing the jewelry piece.
In an embodiment, laser etching is used to form the design of the master template. In another embodiment, the master template is formed by photolithography.
In an embodiment, the metallic material of the master template comprises one or more metals selected from the group consisting of aluminum, nickel, copper, ruthenium, iron, manganese, molybdenum and magnesium. In an embodiment, the metallic material of the master template is formed of stainless steel.
In an embodiment, the polymeric material is formed of rubber. In embodiments, the polymeric material is selected so as to be stable at elevated temperatures. In an embodiment, the polymeric material is stable at a temperature greater than or equal to about 100° C., or greater than or equal to about 200° C., or greater than or equal to about 300° C., or greater than or equal to about 400° C., or greater than or equal to about 500° C., or greater than or equal to about 600° C., or greater than or equal to about 700° C., or greater than or equal to about 800° C., or greater than or equal to about 900° C., or greater than or equal to about 1000° C.
In an embodiment, the design of the master template is an inverse of the design of the jewelry piece.
In an alternative embodiment, a die template is formed from the matrix template. The die template can be formed of a polymeric material. In an embodiment, the die template has a design that is an inverse of the design of the matrix template.
Approximately 18 g of a PMC+ clay (Mitsubishi Materials, 99.9% Ag) was used to form a jewelry item. The clay was initially kneaded. The clay was then shaped in a rough rectangular shape before rolling out. Rolling guides were used to roll the clay to cover a portion of a metallic stamp (template) having a texture defining a design. The rolling guides were approximately 2 millimeters thick. With the clay rolled out, the clay was placed over the lower left hand portion of the stamp. A Teflon sheet was placed over the clay and rolled up and down lengthwise, applying even pressure with each pass. The texture sheet was then rotated about 90 degrees and rolled from side to side, applying even pressure with each pass. After rolling the clay over the stamp, the Teflon and stamp were flipped over. The texture stamp was then peeled off the clay. Excess clay was then removed by cutting around the negative impression of the design in the clay. The clay was then allowed to dry. The dried clay defined a pendant. Next, all sides of the dry pendant were filed (with the aid of sandpaper) to provide smooth edges. A hole was drilled in a top portion of the pendant for hanging the pendant. Next, with the pendant dried completely, the pendant was inspected for cracks. Any cracks were repaired and dried. Next, the pendant was annealed (or fired) in a firing oven at the appropriate temperature and time for the clay product. For PMC+, the pendant was annealed at about 1650° C. for about 2 hours. The fired pendant was then removed from the firing oven and allowed to cool. A brass brush was used to clean away the clay dust from the fired pendant. The fired and cooled pendant was then processed per a desired finishing procedure (e.g., paint finish), dried and polished.
