How Is A Plaster Mold Made To Be Used As An Initial Physical Representation Of The Gold Medal Or Coin?
There are several steps involved in the creation of a "maquette" which is a mold made of plaster, which is based on the style of a silver or gold coin.

The artist begins by sculpting a maquette using the gold design. The plaster is shaped to create a relief or three-dimensional representation of the coin or medal.
Finer and more detailed- The artist concentrates on adding more details, enhancing the contours, while also ensuring accuracy of features and proportions within the design. This stage requires attention to detail and precision.
Giving the plaster time to dry out and setAfter a sculpture is done, it will require some time to set and set. This enables the maquette to harden and hold its shape.
Smoothing and finishing-After drying the surface of the maquette is smoothed and refined to remove any imperfections, bumps, or rough areas.
Preservation and Sealing - To keep maquettes, and to prepare them for future processes for scanning, or mold making, an adhesive or protective layer can be applied.
