Plaster Mixing- Plaster with water are combined to create an even consistency. It's important to have a smooth mixture that is without lumps.
Base Creation- In order to sculpt the maquette it requires a base or platform must be built. This base can be a flat wooden surface, or a piece of board.
The sculpting Maquette - The artist uses the gold design to guide him in sculpting it into the plaster. The process involves shaping the plaster to make a relief, or a three-dimensional model of the coin, or medal.
Refinement and Detailing: The artist will focus on the finer details, changing the shape of the design and making sure that the proportions of the design are precise. This phase requires precision and attention.
The time needed to set and dry- After the sculpting is done, the plaster should be allowed to dry and settle. This will allow the maquettes to set and keep their shape.
The Maquette is finished - after drying, the surface will be smoothed further to eliminate any bumps or rough spots.
Preservation and sealingThe sealant or the protective coating can be applied on the maquette's surface in order to preserve it and prepare it for further processes, such as scanning or molding.
The resultant maquette is used as a tangible three-dimensional representation of the gold coin or medal design. It can be used for several stages in the production cycle, including scanning for digital reproduction, or creating molds for large-scale production.

What Is The Process By Which The Janvier Machine Transfer The Design Of The Gold Coin Onto A Working Hub?
The Janvier machine, sometimes referred to as a pantograph, or reducing machine is a special machine used in the process of minting to transfer an image of a medal or coin from a master hub into the hub that is working. Here is an overview on how this Master Hub Creation works.
The master hub is the primary die or mold that carries the exact shape of the coin or medal. The master hub is generally produced by using CNC machines or other precision methods to ensure accuracy.
Janvier Machine Installation
The Janvier machine is comprised of a stylus, which trace the pattern onto the master hub and a cutting device that replicates the design onto the working hub.
The Janvier machine has an incredibly secure master hub. This serves as the basis upon which the design can be transferred.
The process of tracing a design
The Janvier machine features a stylus that follows the contours, details and shape of the master wheel. The Janvier machine's stylus captures its profile as it moves across the surface.
The Design of the Home
The cutting tool of the Janvier machine reproduces the traced design onto the working hub which is comprised of softer material than the hub that is used as the master, like nickel or steel.
The cutting tool reduces or replicates the design onto the working hub on the smaller or smaller size compared to the master hub. This reduction is essential for the process of coining because it allows coins or medals to be struck in the desired sizes.
Accuracy and Precision
Janvier’s machine works with precision and guarantees a flawless transfer of design information from the master to the working hub. It is able to reproduce even the smallest details and curves.
Quality Control
The resultant hub will be subjected to quality checks and inspection to ensure that the design is in line with the specifications and accuracy needed for the striking process.

How Do You Get Textures Or Matte Surfaces By Sandblasting? How?
This method is used for achieving specific textures or finishes, such as matte and textured surfaces, on the surface of medals or coins. This is the reason and how it's done.
Surface preparation- The medal, coin or other item is placed inside an enclosed chamber or cabinet equipped with an nozzle connected to a compressor. The chamber is able to be enclosed in order to keep the abrasive substance used during the process.
Abrasive Materials Selection- At high speeds, tiny particles of abrasive substances, such as silicon carbide (sand) glass beads or aluminum oxide, are propelled onto the surface of the coin or medal.
High-Pressure Propeller - The abrasive particle is pushed onto surfaces using compressed air. The finish or texture is determined by the force and speed at which particles impact the surface.
Texture Creation: The force from the abrasive grains on the surface produces the appearance of a matte or textured by altering the topography of the surface. This technique can be utilized to create an even texture or roughen specific areas.
Controlled Application: Sandblasting's strength length, duration, and the angles of application can all be adjusted to create various designs or textures. Different types of abrasives and levels of pressure result in different outcomes.
Why you should sandblast
Texture variation - Sandblasting can create a variety of textures and finishes such as glossy grains, frosted, or grainy surface textures. This adds visual appeal to the medals or coins.
Aesthetic Enhancement- Sandblasting alters the appearance of a surface. It helps diffuse light reflections and reduces the shine. This enhances the visual appeal of a coin or medal. Matte finishes may be used to highlight certain elements of the design by reducing the glare.
Anti-Glare - A matte or textured finish that is created by sandblasting will reduce glare or reflections. This makes the coins or medals look attractive and they are much easier to read, without undesirable light interference.
Contrasting Elements in Design- Sandblasting can be employed to create contrasts between areas that are polished or textured on coins or medal. This can be done to emphasize certain features of the design and/or increase the depth and dimension.
Sandblasting allows for customization, which includes artistic expression and creating unique medals or coins that feature textures or finishes customized to meet specific design requirements.

How Do Gold Blanks Get Fed And Stamped With High Pressure In Coin Presses During Minting?
In the process of minting gold blanks are loaded into coin presses, where they are stamped under high pressure to transform into finished coins or medals. Here's a brief outline of how to load blanks.
Gold blanks that have been checked and cleaned for quality, are placed into a feeder system connected to the coin press. The feeder system ensures an ongoing quantity of blanks for the coin press.
Blanks for Feeding to the Press
The feeder system introduces blanks into the strike chamber in the coin press, one at a. This allows for precise placement of each blank for stamping.
Alignment and Positioning-
When using the press, blanks need to be perfectly placed within the area of striking, so that the stamping can occur.
Striking Under Pressure
The coin presses exert immense pressure on gold blanks with a pair dies -- one stationary and one mobile. The stationary die is the negative image of the coin's design, and the one that moves is the hammer that strikes the blank.
The die that is moving strikes the blank with significant force, which transfers the design onto the blank's surface. The pressure of the dies creates the design, as well as the raised relief.
Multiple Striking is an Optional
Multi-strikes are a great option for more expensive coins or medals like proofs or collector's editions. This will result in a sharper and more defined image. Each strike refines the surface characteristics of the blank.
Ejections and Collection
After being struck, freshly-minted coins or medals are released out of the press into containers or trays. The designs that are stamped are examined to determine if they conform to the standards set by the manufacturer.
Post-Processing-
If the mint has specified the process, they can apply additional processes for edge lettering, reeding the edge, or post-strike treatment.
Stamping the gold blanks with the highest pressure is crucial as it imprints the design desired onto the blanks, transforming them into completed coins and medals that can be used for the purpose of commemoration and collection, or even circulation. The stamping process requires preciseness as slight variations in pressure and alignment can influence the final product's quality.
