How Can A Plaster Model Be Used As Physical Representation For The Gold Coin?
It is important to note that the designer or artist will use the gold medal or coin design to guide. The design could be a sketch made with a pencil, or it could be an image created digitally using graphic software. Other materials, like clay or wax, could be used.
Plaster Mixing- Plaster and water mix to create a smooth consistency. It is essential that the mixture be smooth, free of lumps and uniform in order to form the mold.
This base is where the maquettes will be created. The base can be a board of wood or a flat surface that provides stability.
Making a sculpting Maquette The artist makes use of the design of gold to guide him when creating a sculpture of it in the plaster. This involves shaping the plaster to form the relief or three-dimensional representation of the coin or medal.
Detailing and Refinement - The artist creates details that refine the contours of the image and ensures the accuracy of proportions and design elements. This phase requires careful focus on the finer particulars.
Allowing time for drying and Setting- Once the sculpture has been completed, the Plaster needs to be allowed to dry and set. This allows for the maquette's form to be preserved and for its hardening.
Smoothing and finishing - The maquette's surface is further polished and refined after drying to remove imperfections bumps, rough areas and bumps.
Sealing and PreservationIn order to protect the maquette and prepare it for future processes like scanning or molding the maquette, a sealant or protective layer can be sprayed to the surface.
The final model of the maquette is the gold coin or medal design in three-dimensional format. The maquette of plaster is used to create molds to make mass-production production possible as well as to serve as a reference material for the other phases of the production process.

What Is The Process By Which A Janvier Machine Transfer A Gold Coin Or Medal Design To The Hub From The Master?
A Janvier is also known under the name pantograph or reduction machine, is utilized to transfer the design for a coin or medal from a master hub onto an operational hub. The Master Hub Creation is explained in this video.
The master hub is the original die, or mold, that contains the exact design for the coin or medal. It is usually made using CNC machining or other precision methods to guarantee accuracy.
Janvier Machine Setup
The Janvier machine is comprised of a stylus that traces the pattern on the hub master, and a cutting tool that replicates the design onto the hub in operation.
The Janvier machine's master hub, which serves as a template from where the design can be copied, is positioned securely on the machine.
Retracing The Design
The stylus of the Janvier machine follows the contours and details of the design that is on the master hub. As the stylus moves across the surface of the master hub it records the design's profile.
Reduce the Design
The Janvier machine simultaneously copies the drawn-out design onto the hub for work. It is typically made with softer components than the master wheel, for example, steel or nickel.
The cutting tool reduces or replicates the design onto the working hub at the smaller or smaller size compared to the master hub. This allows the cutting tool to create coins and medals of the exact size.
Accuracy and precision
Janvier machines are operated with a high degree of precision to ensure a perfect transfer of designs from the master hub to the working hub. It replicates every detail and contour with accuracy.
Quality Control
The hub that is used for the operation is subject to inspection and quality control to ensure it meets the specifications and accuracy for the strike process.
Further Processing
The Janvier machine creates a working hub for the coin and medal striking process. It can be used to create multiple blanks of the medal or coin with the designs transferred.
Janvier machines are vital for the production of medals and coins. They enable the precise replication of intricate coin or badge designs. The hubs that are working can be used for the production process of mass-produced medals or coins.

What Is The Reason And How Is It Possible To Create Certain Textures Or Finishes Like Matte Or Textured Surfaces?
Sandblasting is a powerful method to create smooth or textured surface on silver or gold coin and medals. This is how and why it's done.
Surface preparation: The coin, medal or other object is put in an enclosed compartment or cabinet with an nozzle connected to compressor. Abrasive materials are usually contained inside this chamber.
Abrasive material selection - High speed propulsion of fine particles of abrasive abrasives, such sand or silicon carbide or glass beads and aluminum oxide on the surface.
High-Pressure Propulsion - Abrasive particles can be delivered to the surface of an object using compressed gas or another high-pressure system. The force and velocity at which the particles strike the surface will create the desired finish or texture.
Texture creation- By altering the surface topography due to the impact of the abrasive particles, the texture is created. It can be used to create an even surface or create rough texture in certain areas.
Controlled Application- Sandblasting may be controlled by intensity, duration, and angle of application to achieve varying textures or finishes. Different abrasives are used to create different effects.

Texture Variation: Sandblasting produces a wide range of textures, which include the grainy, matte and frosted surfaces. These add visual interest as well as unique features to the medals or coins.
Aesthetic Improvement- Sandblasting changes the look of surfaces. It disperses light reflections and decreases the shine. This increases the appearance of a coin or a medal. Matte finishes can be used to highlight certain particular design elements by reducing the reflections.
Anti-Glare - A matte or textured finish that is created through sandblasting can reduce glare or reflections. This makes the coins or medals look attractive and they are much easier to read, without undesirable light interference.
Contrasting Design ElementsSandblasting can create contrast between textured and polished areas of the coin or medal to highlight specific design elements or giving the appearance of depth and dimension.
Customization and Creativity - Sandblasting allows for customization, allowing for artistic expression and the creation of medals or coins with distinctive texture or finish that is customized to meet specific design specifications.
