How Is A Plaster Mold Made To Be Used As An Initial Physical Representation For The Gold Medal Or Coin?
It is crucial to remember that the designer or artist will employ the gold coin or medal design as a guide. This design may be a simple sketch created with a pencil, or it could be a digital image made with graphic software. There are other materials such as wax or clay.
Plaster Preparation- The plaster is mixed with water to form a uniform consistency that is able to be manipulated. It is essential that the mixture is smooth with no lumps and uniform in order to form a mold.
Make the base- The maquette is then sculpted onto a platform or base. This base could be a wooden board or an even surface that gives stability.
Sculpting Maquettes - The artist begins by creating the gold design using it as a reference. This is done by shaping the plaster to create relief or a three-dimensional rendition of the coins or medals.
Detailing and Refinement - The artist adds details that refine the contours of the image and ensures the accuracy of proportions and design features. This phase requires accuracy and focus.
Giving the plaster time to dry out and setAfter a sculpture is finished, it needs some time to cure and set. This will allow the maquette to harden and keep its shape.
After drying the maquette, it's smoothed and finished to remove any bumps, imperfections or rough spots.
Preservation and SealingIn order to protect the maquette, and to prepare it for future processes like scanning or molding the maquette, a sealant or protective layer can be sprayed to the surface.
The plaster maquette is a three-dimensional, tangible illustration of the design for the gold medal or coin. It serves as a physical reference for further stages in the process of making, such as scanning to create digital replicas, creating molds for mass production, or as a model to allow artists to visualize and refine the design prior to final production.

Evacuation by Airplane
The vacuum furnace eliminates the air inside the chamber to create an uncontrolled vacuum, free of oxygen and other gasses. This ensures uniform heating and stops the process of oxidation.
Heating Phase
The furnace must be heated to the temperature needed for hardening the dies. The range of temperature will be determined by the type of material and the hardening process.
Soaking at high temperatures
The material can attain the desired hardness and the metallurgical structures are created.
Cooling or Quenching
After soaking and the dies are then cooling or quenched by using special techniques. The speedy cooling allows the metal achieve the desired level of hardness.
Tempering (Optional)The Tempering Process (Optional)
In some cases there is a process of tempering that follows the process of hardening. Tempering involves heating the dies to a lower temperature in order to relieve stress while maintaining the toughness.
Quality Control and Inspection-
To make sure they meet the standards for hardness and strength the dies that are hardened undergo a thorough inspection and quality control.
Post-Treatment Handling-
The dies, after the process of forming a vacuum is completed, can be further processed using polishing and coating before they are used in the coin striking or medal striking processes.
Vacuum hardening enhances the life endurance, durability, and wear resistance of dies that are used to strike gold coins or medals.
