What Is A Mold Made Of Plaster? Used To Create An Initial Physical Representation For A Gold Coin Or Medal?
Making a mold of plaster or "maquette" based on an actual gold coin or medal design requires a series of steps to translate the two-dimensional image into a three-dimensional physical representation. Initial Design Reference- The artist or designer uses the gold medal or coin design as a source of reference. The design may be a hand-drawn sketch or a digital representation that is created with graphic design software.Choosing a Medium- Plaster is a common material used for maquettes due to its flexibility and ease of sculpting. Other materials, such as clay and wax may be used.
Plaster Mixing - Plaster and water are combined to create a smooth consistency. The mixture must be smooth and free of lumps in order to make sure that the mold is clean.
The BaseThe base, also known as a platform is prepared where the maquette will be sculpted. It is typically an unfinished wooden board or a flat, stable surface.
The Maquette is created using the gold pattern as a reference. This is the process of shaping plaster into a three-dimensional or relief image of the coin.
Detailing and Refinement- The artist focuses on adding details and refinement of the contours and making sure that the design is accurate in proportions and features of the artwork. This stage requires precision and attention to particulars.
Allowing Time for Drying and Set- After the sculpture has been completed, the Plaster needs to allow time to set and dry. This allows the maquettes to harden, and maintain their shape.
After drying the maquette it is finished and smoothed to eliminate any imperfections, bumps or rough areas.
Preservation and sealingSealing and preservation - A protective coating may be put on the maquette's surface to protect it and prepare it for further processes, such as molding or scanning.
The plaster maquette is a 3D physical representation of the design for an gold medal or a coin. It is used as a physical guide for the subsequent steps of production, such as digital reproduction, mold creation to make mass production, or for artists to work on and refine the concept prior to production.

Why Do Dies Used To Strike Gold Coins And Medals Undergo Processes Of Hardening By Vacuum?
Vacuum hardening is a process that involves exposing dies to high temperature and controlled environment in furnaces. Here's the overview for the dies for vacuum hardening.
Dies used for making medals or coins are created by making sure they are free of any traces of contamination or residues.
Injecting Vacuum Furnace-
The dies can be placed into a vacuum oven, that creates a vacuum within the heat-treatment area.
Evacuation via Airplane
The vacuum oven eliminates any air in the chamber making it a clean space free of oxygen and other gases. This guarantees uniform heating, and also prevents the process of oxidation.
Heating Phase
The furnace is heated to the desired temperature to allow for the hardening of the dies. The temperature range depends on the material used and the hardening process.
Soaking at High Temperatures-
The dies will be maintained at an elevated temperature for the time required to ensure the material attains and keeps the required hardness.
Quenching (or Cooling)
After the soaking, dies need to be quickly cooled by specialized methods. The rapid cooling helps the metal to achieve the desired level of hardness.
Tempering (Optional)The Tempering Process (Optional)
In certain cases, a tempering process follows the hardening process. Tempering involves heating dies to a lower temperature to reduce internal stress and increase durability while maintaining the their hardness.
Quality Control and InspecQuality Control and Inspec
Dies with hardened surfaces are subjected to strict quality inspections and checks in order to meet the standards for strength, hardness and dimensional tolerances.
Post-Treatment Handling-
The dies, after the process of forming a vacuum is complete, could be further processed like polishing and coating prior to when they are used in coin striking or medal striking methods.
The method of vacuum hardening improves die durability, wear resistance, as well as the lifespan of dies used to strike silver or gold coins and medals. The process of vacuum hardening is an efficient and reliable method to harden dies in a controlled and safe environment free of any contaminants.
