What Is The Process By Which A Mold Of Plaster Is Made To Be Used As An Initial Physical Representation For The Gold Medal Or Coin?
It is important to note that the artist or designer will use the gold coin or medal design to guide. This design may be a sketch made by hand, or it may be an image created digitally with graphic software. There are other materials like wax or clay.
Preparation of Plaster - Plaster is mixed with water to create an easily workable consistency. It is important to create a smooth mixture that is without lumps.
The Base- A base or platform is created where the maquette will be created. The base can be a wood board or an even surface that gives stability.
Making the MaquetteUtilizing the gold design as a guide The artist then begins to sculpt the design into the plaster. This involves shaping plaster into relief, or a three-dimensional rendition of the coins or medals.
Detailing & Refinement The artist will be focusing on creating fine details, refining the contours of the design, and ensuring that the proportions of the design are precise. This process requires precision and a keen eye for detail.
Allowing time for the plaster to dry out and harden- Once a sculpt is completed, it requires some time to set and set. This allows the maquette to harden and keep its shape.
The Maquette is finished - after drying, the surface will be further smoothed to remove any bumps and rough areas.
Sealing and Preserving - To keep and protect the maquette, and also to prepare it for other processes such as scanning and molding, apply a sealant or protective layer to its surface.
The 3D plaster model that results is used to illustrate the gold design on the medal or coin.

How Can The Janvier Machine Transfer The Gold Coin Or Medal Design To The Hub From The Master?
The Janvier Machine, also known as a pantograph machine or a reducing device, is a machine used in the coining process to move designs from a Master Hub an Working Hub. This is a brief description of the Master Hub Creation.
The master hub is the primary coin die, or medal mold. It is produced by CNC machining, or using other precision techniques.
Setup for Janvier Machine-
The Janvier machine consists of a stylus that traces the design onto the master hub as well as cutting tools that copy the same design onto the operating hub.
The master hub is securely placed on the Janvier machine, serving as a template upon where the design can be transferred.
The design is traced
The Janvier stylus in the machine captures the profile of the design when it moves across the surface of the master hub. When the stylus travels across the surface, it captures the design profile.
Reduce the Design
Simultaneously the Janvier cutting tool of the machine copies the traced design on to the hub in use. The hub is constructed of a softer metal that the master typically steel or nickel.
The cutting tool cuts, or copies the design to the working hub with a smaller or less dimension compared to the hub that is master. This is essential to the process of minting as it allows for the making of medals or coins at the exact size.
Accuracy and Precision
Janvier is a precise machine that assures a perfect transfer of designs from the master hub onto the working hub. It replicates every detail and contour with precision.
Quality Control
Quality checks and inspections are conducted to confirm that the design transferred matches the requirements and accuracy needed to strike the design.
Further Processing
The Janvier machine's hub of working is used to create coins or medals. The mold or die is used to produce numerous coin blanks or medal blanks by using the transfer design.
The Janvier machine plays an essential part in the process of minting by allowing the exact reproduction and reduction of intricate designs on medals and coins from a hub that is working to a master hub. These hubs work to produce large quantities of coins or medals through the striking procedure.
