The preparation of Plaster is combined with water to form an easily workable consistency. It's essential to make a consistent mixture that's free of lumps.
Make the base- The maquette is then sculpted onto the base or platform. This base could either be a board of wood or a flat surface that offers stability.
Artists who create sculpting maquettes begins by creating the gold design using it as a guide. This is done by shaping the plaster into relief, or a 3-D rendition of the coins or medals.
Detailing Accuracy, Refinement and Detailing The artist's primary focus is adding the details and reworking contours. They also ensure accuracy in the proportions. This requires careful attention to the finer details and accuracy.
Allowing for drying and settingAfter the sculpting process is complete, the plaster needs time to dry and set. This allows for the maquette's form to remain and also for hardening.
Smoothing and finishing Finishing and Smoothing - The maquette's surfaces are later polished and refined following drying to remove imperfections bumps, rough areas and bumps.
Preservation and Sealing - To protect maquettes and make them ready for future processes for scanning, or mold making, an adhesive or protective layer can be applied.
The three-dimensional plaster maquette which results can be used to depict the gold pattern on the medal or coin.

How Can A Janvier Transfer The Gold-Colored Design Of A Coin Medal That Is On The Master Hub Into A Working Hub?
The Janvier Machine, sometimes known as a pantograph machine or a reducer is a tool used in the coining process to transfer designs from a Master Hub a Working Hub. Here's a brief overview of how it accomplishes this Master Hub Creation-
The master die is the original mould or die which contains the exact design of the coin. The master hub is usually produced with CNC machining techniques or other techniques to ensure precision.
Janvier Machine - Installation and Setup
The Janvier machine has stylus, which copy the design of the master hub onto the working hub.
The Janvier machine comes with a master hub that serves as a template for the transfer of design.
Tracking The Design
The Janvier machine has stylus that is able to follow the contours, details and design of the master wheel. As the stylus moves over the surface, it captures the design profile.
Reducing the Design
The Janvier machine can also reproduce the pattern traced on the working hub. The hub is usually constructed from a soft material, such as nickel or steel, as opposed to the hub used in the master.
The cutting tool cuts, or duplicates the design to the hub that is working at a reduced or smaller scale as compared with the hub that is master. This reduction is vital to the process of minting because it permits the sculpting of medals or coins in the size you want.
Accuracy and Precision
Janvier is a precision machine that ensures an accurate transfer of design from the master hub to the working hub. It reproduces every aspect and contour accurately.
Quality Control
The hub that is used for the operation will undergo inspection and quality control to ensure that it meets the specifications and is accurate for the strike process.
Further Processing
The Janvier machine creates a working hub that is used in the coin and medal making process. It is used as a mold or die to create multiple medals or coins that are blank and have the transfered design.
The Janvier machine's role is crucial for the minting process it allows the replication and reduction of complex medal or coin designs from a master hub to working hubs precisely. These working centers are then utilized to create large amounts of medals and coins by using the striking method.
