A gold coin or gold medal design is used as a reference for design by the artist or designer. The design could be drawn by hand or an image created with graphics design software. Other materials, such as wax and clay can be used.
Plaster Mixing - Plaster and water are mixed to form an even consistency. It is essential that the mix is smooth, free of lumps and uniform to create an environment for mold.
The base is where the maquettes will be sculpted. The base can be a wooden board or an even surface that gives stability.
The artist will start by sculpting a maquette using the gold-colored design. It involves shaping the plaster to create a relief, or three-dimensional version of the coin or medal.
Refinement and Detailing- The artist concentrates on adding more details, refining the contours, and ensuring the accuracy of the proportions and features of the artwork. This stage demands precision and attention.
Giving time for drying and Setting- Once the sculpture is completed the plaster must allow time to set and dry. The maquette will set and keep its shape.
Smoothing and finishing-After drying the surface of the maquette is smoothed, then refined to remove bumps, imperfections, or rough areas.
Preservation and Sealingto preserve the maquette, and to prepare it for other processes such as scanning or molding the maquette, a sealant or protection layer could be applied on the surface.
The three-dimensional plaster maquette which results can be used to represent the gold design of the medal or coin. It's used as a reference point to further steps in the process of making like scanning to create digital replicas, creating molds for mass production or as a model for artists to envision and improve the design before final production.

Heating Phase-
The furnace is then heated to the desired temperature for the hardening of dies. The temperature range varies based on the material and process of hardening.
Bathing in high temperatures
The dies must be held at the high temperature for a certain period of time in order for the material to attain and maintain its desired level of hardness.
Cooling or cooling down
After the soaking phase after which the dies are quickly cooled by using special methods. This rapid cooling process helps keep the desired hardness and strength in the material.
Tempering Options
In some instances, the process of hardening can be then followed by a tempering process. Tempering involves heating dies to a lower temperature in order to relieve internal tensions and increase toughness.
Quality Control and Inspection
Die dies are subjected to rigorous quality checks and inspections to make sure they are in compliance with the requirements for hardness, strength, and dimensional tolerances.
Post-Treatment Handling-
Once the vacuum hardening process is complete, the dies may undergo additional processes such as polishing or coating before they are employed in the coin or medal striking process.
The method of vacuum hardening improves the durability of dies, wear resistance, as well as the lifespan of dies used to strike gold or silver coins and medals.
