This is the base on which maquettes will be created. This base can be an unfinished wooden surface or an actual board.
The Maquette is created using the gold pattern as a model. The plaster is then cut into a relief, or 3D image of the coin or medal.
Detailing and Refinement- The artist concentrates on adding more details while refining the contours and making sure that the design is accurate in dimensions and characteristics of the design. This stage involves the utmost precision and concentration on the small details.
Allowing for drying and setting After the sculpting procedure is complete, plaster must be given time to dry. This allows for the maquette's form to be preserved and for its hardening.
After drying, it's finished and smoothed to remove any imperfections, bumps or 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 future processes like molding or scanning.

Abrasive material selection- High speed propulsion of small particles of abrasive abrasives, such sand or silicon carbide, or glass beads and aluminum oxide onto the surface.
High-Pressure propulsion: Abrasive particles can be delivered to the surface of a surface with compressed gas or a different high pressure system. The finish and texture of the surface is dependent upon the force and velocity that the particles strike the surface.
Texture creation: By altering the surface topography due to the effect of the abrasive particle, the texture is created. This is used to create a smooth surface or to create rough textures in certain areas.
Controlled Application - Sandblasting intensity, duration, angle, and application can be adjusted to achieve different surfaces or textures. Different pressure levels and abrasives produce different results.
Sandblasting - Why it is done
Texture variation - Sandblasting can create a variety of textures and finishes, including glossy grains, frosted, or grainy textured surfaces. This adds visual appeal to coins or medals.
Aesthetic enhancement- Sandblasting may alter the appearance of a surface by diffusing light and reducing shine. This can improve the appearance of a coin. Surfaces that are matte, like those that reduce glare, can highlight specific design details.
Anti-glare Properties - The matte or textured finishes created by sandblasting can reduce reflectivity and glare, which makes coins and medals easier to look at and more attractive.
Contrasting Design Elements. Sandblasting creates contrast between polished and those that are textured on the coin. Sandblasting can be used to highlight specific design elements or to create visual depth.
