How And Why Is It Possible To Achieve Certain Finishes Or Textures, Such As Matt Or Textured Surfaces?
Sandblasting is a technique employed to produce certain textures or finishes that include smooth or textured surfaces on gold coins or medals. This is how and why it's done.
Surface preparation - The medal or medal is put inside a cabinet, chamber or nozzle attached to an air compressor. The abrasive material is usually contained inside the chamber.
The medal or coin is then sprayed with abrasive material, which may comprise glass beads, sand silicon carbide, or aluminum oxide.
High-Pressure-The abrasive grains are propelled onto the surface using compressed air or another high-pressure equipment. The texture or finish is determined by the force and speed at which the particles strike the surface.
Texture Creation – The impact of abrasive powders on the surface changes the topography, creating the appearance of textured or matte. It can be used to create a smooth surface or to create rough textures in specific areas.
Controlled Application - Sandblasting intensity and duration, as well as angle and application can be controlled to create different surfaces or textures. Different abrasives are employed to create different effects.
The reasons for sandblasting
Texture Variation: Sandblasting is a great method to create different textures or finishes on medals and coins including matte or frosted surfaces. It adds visual appeal and distinct characteristics.
Enhances the aesthetics of a surface - Sandblasting can modify the appearance of a surface as well as diffuse light reflection and even reduce shine. This can enhance the value of the coin or medal's aesthetic appeal. Matte finishes, for example can highlight certain designs by reducing the the glare.
Anti-glare properties - The matte or textured surfaces produced by sandblasting reduce reflection and glare, making metals and coins more pleasant to see and more appealing.
Sandblasting Creates Contrasting Design Elements Sandblasting can create a contrast between the polished and the texture areas on the medals or coin, highlighting certain design features or giving visual depth.
Sandblasting offers a variety of customization options that allow for artistic expression, and permits medals, coins, or other items to be made with unique distinct textures or finishes that are unique to the style.
