How And Why Are Certain Surfaces, Such As The Matte Or Textured Surfaces, Achieved Through Sandblasting?
Sandblasting is an effective technique for creating matte or textured surfaces on silver or gold coin and medals. This is the reason and how it is used.
Surface preparation - The coin or the medal is placed into a chamber, cabinet or nozzle attached to an air compressor. The chamber is usually covered to protect the abrasive material that is used in the process.
Abrasive Material Select- Abrasive particles such as glass beads, aluminum oxide, silica carbide, and sand are launched at high speed on the surface.
High-Pressure Propulsion - Abrasive particles are launched onto the surface by using compressed gas or another high pressure system. The texture and finish of the surface depends upon the force and velocity at which the particles hit the surface.
Texture Creation: The force of the abrasive particles on the surface produces the appearance of a matte or textured by altering the topography of the surface. This process is able to create a specific roughness in specific areas or produce an even texture throughout the entire surface.
Controlled Application - Sandblasting intensity, duration, angle, and the application of sand can be controlled to achieve different textures or surfaces. Different abrasives can produce different results.
Sandblasting is a reason why it's done
Texture variations- Sandblasting permits the creation of various types of textures and surfaces, such as mattes, frosted or even grainy surfaces. This can create an aesthetic appeal and adds unique characteristics to coins or medals.
Aesthetic enhancement- Sandblasting may alter the appearance of a surface by diffusing light and decreasing shine. This could enhance the appeal of the coin. Matte finishes can help to emphasize certain elements of the design by reducing the glare.
