Sandblasting — glass
Sandblasting carves and textures surfaces, creating a distinctive matte finish. While versatile, it truly *shines* when applied to glass, offering unique depth and tactile appeal for custom awards.
Sandblasting is a subtractive surface marking method that uses abrasive particles propelled at high speed to remove material. This process creates a depressed, matte texture on the surface, which you can feel under your finger. The depth of this depression is controlled by how long and intensely the area is blasted. While effective on various materials, sandblasting is most commonly and powerfully used for glass, where it opens up significant possibilities for intricate carving and artistic effects. From simple logos on frosted mugs to complex, multi-layered designs on prestigious awards, sandblasting transforms ordinary glass into something extraordinary. It offers a unique tactile and visual experience that sets custom awards apart.
Matte texture & depth
*A tactile finish with controlled carving*
Sandblasting creates a distinct matte, frosted appearance by eroding the surface material. Unlike a smooth, polished finish, the sandblasted area has a subtle depression and a rougher texture that catches the light differently. This technique offers precise control over depth; holding the nozzle longer in one spot allows for deeper carving. This ability to vary depth can create a pseudo-three-dimensional effect, especially effective when applied to the back surface of a glass award. Viewed from the front, text or logos appear to be carved deep within the glass, adding an impressive sense of substance and artistry.
Color filling options
*Enhance your design with vibrant hues or metallic sheen*
After sandblasting, the textured surface is ideal for adding color, offering two distinct methods. UV printing allows for a full spectrum of colors, including tonal gradients, directly onto the matte surface. This process creates a highly durable finish, as the ink adheres exceptionally well to the roughened texture, often outperforming prints on smooth glass. Alternatively, paint filling provides a classic, high-end look, particularly with metallic finishes like gold, silver, or bronze. This method offers superior mechanical and chemical durability, resisting moisture and wear. It's perfect for distinguishing award tiers, such as gold for first place, silver for second, and bronze for third. Combining paint-filled sandblasting with CO2 laser engraving can add intricate graphic motifs on top of the painted surface for a truly exclusive finish.
Sculpting with depth
*Creating a captivating 3D illusion within glass*
Deep sandblasting takes the standard process further, extending the blasting time to achieve significant depth, often several millimeters. This technique is particularly impactful when applied to the back surface of a glass award in a mirrored reflection. When viewed from the front, the design appears to be a three-dimensional object suspended inside the glass, creating a striking optical illusion. This method is not just for logos; it can be used for artistic sculpting, adding a profound sense of depth and presence to custom glass figurines and awards. The result is a truly immersive visual experience that elevates the piece beyond a simple surface engraving.
Frosted glass & edge refinement
*Beyond patterns: practical applications for glass*
Beyond creating specific patterns, sandblasting is also invaluable for general glass finishing. It's commonly used to refine edges that might be sharp or uneven after cutting, providing a smooth, matte finish where a polished edge isn't necessary or desired. The rest of the glass is carefully masked, ensuring only the edge is treated. Another popular application is full-surface matting, where the entire glass item or figurine is sandblasted. This process creates what's known as 'frosted glass,' giving the piece a uniform, elegant white-gray translucent appearance. This technique is often chosen for its clean aesthetic and ability to diffuse light beautifully.

Working with sandblasting.
What materials can be sandblasted?
While sandblasting is a versatile technique applicable to various materials, it is most commonly and effectively used for glass. On glass, it allows for unique depth and texture that other materials don't fully leverage. For other materials, we'd typically recommend alternative engraving methods that might offer better results or be more cost-effective.
How does sandblasting compare to laser engraving?
Both create surface markings, but sandblasting offers a deeper, more tactile depression and a distinct matte finish. Laser engraving often provides finer detail and a smoother, sometimes frosted, but less physically deep mark. Sandblasting excels at creating pseudo-3D effects and preparing surfaces for durable color filling, especially on glass.
Can I add color to sandblasted awards?
Yes, absolutely. We offer two primary methods: UV printing for full-color gradients and vibrant hues, which adheres exceptionally well to the matte texture. Alternatively, paint filling provides a durable, high-end finish, particularly with metallic colors like gold, silver, and bronze, perfect for a prestigious look.
What are the aesthetic benefits of sandblasting?
Sandblasting delivers a unique matte, frosted appearance with a tangible texture. It allows for controlled depth, creating striking pseudo-3D effects where designs appear carved within the glass. It also provides an ideal surface for durable color application and can transform an entire piece into elegant frosted glass.
How does deep sandblasting create a 3D effect?
By extending the blasting time, we can carve several millimeters deep into the glass. When this deep carving is done on the back surface of an award (in reverse), and viewed from the front, it creates an optical illusion. The design appears to be a three-dimensional object suspended within the glass itself, adding significant visual impact.
