What Are The Advantages Of A Plaster Mold Used To Make An Initial Physical Representation For A Gold Coin Or Medal?
A gold coin or medal design can be used as a reference for design by the designer or artist. This can be a sketch created either by hand or as a digital image created with graphic design software. Selecting a medium- Plaster due to its malleability, is often employed for maquettes due to its malleability. Clay or wax can also be utilized.
Plaster Preparation: The plaster is mixed with water in order to create a smooth consistency that can be manipulated. It is important to create a consistent mixture that's without lumps.
Create the base- The maquette is then sculpted onto the base or platform. The base could be a plank of wood or a flat surface that provides stability.
The artist will start by creating a maquette of the gold design. This involves shaping plaster to create relief or a 3-D rendition of the coins or medals.
Detailing Accuracy, Refinement and Detailing The artist's focus is on creating details and refining contours. They also make sure that they are accurate in the proportions. This phase requires precision and attention.
Allowing Time for Drying and Set-up- After the sculpture has been completed the plaster must be allowed to dry and set. This will allow the maquettes to harden, and maintain their shape.
After drying, the surface gets smoothed to eliminate bumps or imperfections, as well as rough areas.
Sealing and Preservation - To protect maquettes and prepare them for future processes, such as scanning or mold making, an adhesive or protection layer is applied.
The maquette of plaster is a three-dimensional tangible representation of the design for an gold medal or a coin. It acts as a tangible reference for the next stages in production. For example, it can be used to create digital replicas or create molds for bulk production. Artists can utilize it as a reference to conceptualize and improve their designs prior to the finalization of their design.

Why Do Dies Used To Create Gold Coins And Medals Undergo Processes Of Hardening By Vacuum?
The technique of vacuum hardening is used in the production of gold-plated coins or medals. The process involves heating the dies at high temperatures, and expose them to controlled conditions inside the confines of a vacuum. This is an overview of the process of vacuum hardening of dies.
It is essential that the dies used to strike coins and medals are free of any dirt and other contaminants.
Moving into Vacuum Furnace
The dies can be placed in a vacuum oven which creates a vacuum in the heat-treatment area.
Evacuation from Air
The vacuum furnace eliminates the air inside the chamber to create a controlled vacuum, devoid of any oxygen or other gases. This prevents oxidation and also ensures a uniform heating.
Heating Phase -
The furnace has to be heated to the temperature necessary to harden the dies. Temperatures can vary based on the material used and the processing for hardening.
Soaking in High Temperatures
The material can attain the desired hardness, and the metallurgical structure is created.
Cooling or cooling down
After soaking, the dies need to be quickly cooled with special methods. The speedy cooling allows the metal to achieve the desired hardness.
Tempering (Optional).
In some instances, a tempering process follows the process of hardening. Tempering is the process of heating dies to a lower temperature, which helps reduce internal stress and increase the toughness of the die while maintaining its toughness.
Quality Control and InspectionQuality Control and Inspection
The dies that have been hardened are examined and tested to make sure that the dies meet all of the specified requirements.
Post-Treatment Handling-
After the hardening process dies can be polished or coated prior to the time they are utilized in the coin or metal strike process.
The process of vacuum hardening increases the wear resistance, durability and longevity of dies used to make gold medals or coins. This process creates a controlled atmosphere free of airborne contaminants to ensure consistent and reliable hardening. It also improves the overall quality of the final product.

Surface preparation- The medal or coin is placed inside a chamber or cabinet equipped with a nozzle that is connected to an air compressor. This chamber is usually enclosed to keep the abrasive used during the process in a sealed.
The coin or medal is then sprayed with abrasive material, which could include glass beads, sand silicon carbide, or aluminum oxide.
High-Pressure Propeller- The abrasive particle is launched onto surfaces using compressed air. The force and speed at which the particles hit the surface produce the desired texture or finish.
Texture creation. The effect of abrasives on a surface alters its topography to produce a rough, matte finish. It can be used to create an even surface or create a rough texture in specific areas.
Sandblasting can be controlled in terms of intensity, duration and angle adjusted to create various textures or finishes. Different pressure levels or abrasives yield different results.
Sandblasting - Why it is done
Texture Variation: Sandblasting can allow to create diverse textures or finishes, like matte, frosted, or even grainy surfaces, adding visual interest and unique particularities to the coins or medals.
Aesthetic Enhancement- Sandblasting alters the look of surfaces. It helps diffuse light reflections and reduces shine. This enhances the visual appeal of a medal or coin. Matte finishes in particular, draw attention to particular design elements since they reduce 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 more attractive, and they are easier to read without any undesirable light interference.
Contrasting Elements in Design- Sandblasting can be used to create contrasts between different areas which are polished or textured on a coin or medal. This is done to highlight specific design elements or give dimension and depth.
Sandblasting can be customized for distinctive textures or designs.
Sandblasting is an ingenuous method that can be applied on gold coins in order to create various surface textures. It also improves the overall appearance of the coins.
