What Is The Process By Which A Mold Of Plaster Is Designed To Serve As An Initial Physical Representation Of The Gold Coin Or Medal?
The design may be drawn by hand or a digital image created by using graphic design software. The design may be made in digital form or using graphic design software. It can also be a hand drawn sketch. Other materials, such as wax and clay could be used.
Preparation of Plaster- Plaster is mixed with water to make an able consistency. The mixture should be smooth and free of lumps to create an effective mold.
This base is where the maquettes will be sculpted. This base can be a flat wooden surface or a board.
The artist will start by creating a maquette of the gold-colored design. This involves shaping plaster to create relief or a three-dimensional rendition of the coins or medals.
Refinement and Detailing The artist will be focusing on the finer details, changing the contours of the design, and making sure that the proportions of the design are correct. This requires careful attention to detail and precision.
Allowing for Drying and SettingAfter the sculpting process is done, the sculpted needs time to dry and set. This allows for the maquette's form to be preserved and for its hardening.
After drying, the surface is refined to remove bumps and rough spots.
Sealing and preservationSealing and preservation - A protective coating is applied on the maquette's surface in order to preserve it and prepare it for subsequent processes such as molding or scanning.
The resultant maquette is used as a tangible, 3D depiction of the gold coin or medal design. It serves as a physical reference for further stages in the process of making like scanning to create digital replicas, creating molds to make mass production, or as a model to allow artists to envision and improve the design before final production.
