How Can A Plaster Model Be Used To Create A Physical Representation To The Gold Coin?
A gold coin or medal design can be used to serve as a design reference for the designer or artist. The design could be drawn by hand or a design created using graphics design software. Other materials, such as clay or wax, could also be used.
Plaster Preparation- The plaster is mixed with water to achieve a consistency that can be manipulated. To ensure a clean mold the mixture should be smooth and free of lumps.
Making the Base- Make a base, or platform where the maquette sculpture will be done. This base may be a wooden plank, or an even surface for stability.
Sculpting the MaquetteUtilizing the gold design as a guide The artist starts sculpting the design onto the plaster. It is the process of shaping the plaster to make a relief, or three-dimensional version of the coin or medal.
Detailing & Refinement: The artist will focus on the finer details, changing the shape of the design and ensuring that the proportions of the design are accurate. This process requires precision and a keen eye for detail.
Allowing for drying and setting After the sculpting process has been complete, plaster must be given time to set and dry. This allows the maquette's form to be retained and its hardening.
After drying, it's finished and smoothed to eliminate any bumps, imperfections or rough spots.
Preservation and SealingIn order to protect the maquette and make it ready for future processes like scanning or molding, a sealant or protection layer could be applied to the surface.
The maquette of plaster is an 3D physical illustration of the design for an gold medal or a coin. It serves as an exact reference for the next stage of production. It can be used to scan for digital replication or to create molds for mass production. Or, artists can make use of it as a model to visualize and improve their designs prior to final production.

How Can The Janvier Machine Transfer Gold Coins Or Medals Design To The Hub Of The Master?
A Janvier machine is also called a pantograph or reducing machine. It is employed to transfer the designs of a coin or medal from a master into the working center. Here's a quick overview of this Master Hub Creation.
The master hub is the original mold or die that contains the exact layout of the coin or medal. To ensure precision, it's typically produced using CNC machining and other precision techniques.
Janvier Machine Setup
The Janvier machine is comprised of a stylus that traces the design on the master hub and cutting tools that copy the design on the working hub.
The Janvier machine has a master wheel that is connected to the machine. It is used as a model, from which designs will be transferred.
Tracing the design-
The Janvier stylus in the machine captures the profile of the design as it moves across the hub's surface. When the stylus travels across the surface, it captures the design's outline.
Reduce the Design
The Janvier cutting tool of the machine transfers the design traced on to the working hub. The hub is constructed of a softer metal that the master typically steel or nickel.
The cutting tool reduces or transfers the design onto the hub of the wheel in a smaller scale or size in comparison to the master hub. This reduction allows for striking coins and medals of the desired size.
Precision and Accuracy-
Janvier's machine is operated with precision, ensuring an accurate transfer from the master hub to the working hub. It faithfully recreates the smallest contours and details.
Quality Control
The hub's working part will undergo inspection and quality control to make sure that it is in line with the specifications and is accurate for the striking procedure.
Further Processing
The Janvier's hub can be utilized as an instrument for the making of medals and coins. It is used as a mold or die that is used to make multiple coin or medal blanks with the transfer design.
Janvier machines are crucial in the creation of medals and coins. They enable the precise reproduction of intricate coins or badge designs. These working centers are then utilized to create large amounts of coins and medals through the strike method.

Consistency in the Striking. Hand polished dies produce a consistent striking face, which ensures uniformity throughout the minting procedure. Consistency is vital to ensure the accuracy of the design, its depth and overall quality across several medals or coins.
Longevity and durability of Dies- Well polished dies are less susceptible to damage or wear when struck. They are more durable, and can be used for longer strikes without compromising quality.
Accuracy and Precision - Hand polishing allows the engraver to fine tune specific areas of dies, ensuring that the exact details are reproduced on struck coins or medals. This precision is important for the accuracy of the final product.
Quality Control Polishing is an essential part of quality control. Examining the die in the process of hand polishing will allow the identification and correcting any flaws before striking.
Surface Finishing - Polishing creates specific surface finishes and textures that improve the visual appeal or give unique qualities to struck coins and medals.
