What Is A Mold Made Of Plaster? Used To Make An Initial Physical Representation For A Gold Coin Or Medal?
A gold coin or medal design is utilized as a reference for design by the artist or designer. This design can be drawn with a pencil or pen, or an image created with graphics design software. Clay or wax can also be used.
Plaster Mixing- Plaster and water are mixed to form an even consistency. It's important to have an even mixture that is free of lumps.
Create the base- The maquette is then sculpted onto a platform or base. This base may be a wooden plank or a flat surface to provide stability.
The Maquette is sculpted by using the gold design as a reference. The process involves creating a shape in the plaster to create a relief or three-dimensional representation of the coin or medal.
Detailing Precision, Refinement, and Accuracy The artist's focus is on making the details more clear and reworking contours. They also guarantee accuracy in the proportions. This requires careful attention to the finer details and accuracy.
Allowing for drying and setting Once the sculpting process is complete, plaster must be allowed to set and dry. The maquette will set and retain its shape.
Following drying, the surface gets refined to remove bumps, imperfections or rough areas.
Sealing and Preserving - To keep and preserve the maquette, and to prepare it for other processes like scanning and molding, apply a protective or sealant layer to the surface.
The resultant maquette is used as a tangible, 3D representation of the gold medal or coin design. It's used as a reference to physical objects for the next steps of the production process including scanning to create digital replicas, creating molds for mass production, or as a model to allow artists to conceptualize and refine the design prior to final production.

How Can The Janvier Machine Transfer A Gold Coin Or Medal Design To The Hub Of The Master?
The Janvier machine, sometimes referred to as a pantograph or reducing device is a device used in the process of minting that transfers a coin or medal design from a master hub to an operational hub. The Master Hub Creation is explained in this video.
The master hub, sometimes referred to as the original die or mould, is the first mold or die that contains the exact layout and design of the coin. It is made through CNC machining, or using other techniques of precision.
Janvier Machine - Installation and Setup
The Janvier machine is comprised of a stylus that trace the design on the master hub and an instrument for cutting that reproduces the design on the working hub.
The Janvier machine is fitted with a master hub that acts as a template to guide the transfer of the design.
Tracing the design-
The Janvier machine's stylus records the shape of the design when it moves across the hub's surface. As the stylus moves across the surface of the hub master, it records the design's profile.
The reduction of design-related
In tandem with the Janvier the cutting tool copies the designs traced onto the hub of the machine which is normally made out of an abrasive material such as steel or Nickel.
The cutting device cuts or transfers the design onto the hub of the working wheel, but at a lower scale or size in comparison to the master hub. This is essential for the process of minting because it allows for the striking of medals or coins at the exact size.
Accuracy and precision
Janvier machines are controlled precisely to ensure the exact transfer of the design from the master hub to the operating hub. It reproduces every aspect and contour accurately.
Quality Control
The resultant hub will be subjected to quality checks and inspection to ensure that the transferred design matches the specifications and precision required for the process of striking.
Further Processing
The Janvier's hub can be utilized as an instrument in the striking of coins and medals. The die or mold is used to create multiple medal or coin blanks using the transferred design.
Janvier machines are essential in the creation of medals and coins. They allow the precise reproduction of intricate coin or badge designs. These hubs then are utilized in the mass production of medals or coins by striking.

What Are The Benefits Of Sandblasting Certain Textures Or Finishes Like Matte Surfaces Or Textured Ones?
Sandblasting can create matte or textured surfaces on gold medals and coins. The technique is employed to achieve a number of different reasons.
Surface preparation - The medal or the medal is put inside a cabinet, chamber or nozzle connected to an air compressor. The chamber is able to be sealed to contain the abrasive substance employed during the process.
The coin or medal is then coated with abrasive substance, which can comprise glass beads, sand silicon carbide, or aluminum oxide.
High-Pressure Propeller: The abrasive particle is propelled onto the surfaces using compressed air. The finish or texture is determined by the force and speed at which the particles strike the surface.
Texture Creation: The impact caused by the abrasive grains the surface creates a matted or textured look by altering the topography the surface. This can be used either to create a smooth surface or to create rough textures in certain regions.
Sandblasting can be controlled in terms of intensity, duration, and angle controlled to produce different textures or finishes. Different abrasives, pressure levels and abrasives result in different outcomes.
Sandblasting is why it is necessary?
Texture variation - Sandblasting can create a variety of textures and finishes such as smooth and grainy, frosted, or surface textures. This adds visual interest to the medals or coins.
Aesthetic enhancement- Sandblasting may alter the surface appearance by diffusing light and decreasing shine. This could enhance the appeal of the coin. Matte finishes can in particular, draw attention to certain design elements as they reduce the glare.
Anti-glare properties - The matte or textured finishes produced by sandblasting reduce reflection and glare, making the medals and coins easier to look at and more attractive.
Sandblasting Creates Contrasting Design Elements - Sandblasting creates a contrast between polished and texture areas of the medal or coin, emphasizing particular design elements or giving visual depth.
Customization and Creativity- Sandblasting provides a variety of customization options, which allows for creative expression as well as the creation of coins or medals with distinctive texture or finish that is customized to meet specific design specifications.
