You can pick from 3 techniques to sandblast, or etch, designs into your shower glass. All 3 processes, explained below, are done on tempered glass to create infinite sandblasted graphics, logos, themes and more. Surface Etching: This technique is the first, most basic, and least expensive process. Surface etching is a single-stage sandblast option that produces a full opaque effect. As its name implies, only the surface is sandblasted. Since etching does not go deep into the glass, it yields a one-dimensional look. Surface Etching & Shading: This process is the second level of sandblasting. Surface etching and shading is a multi-stage sandblast effect. Each and every segment of the illustration is individually removed and sandblasted, one piece at a time. This is not a surface etch, but areas are shaded so the image delicately and gradually fades back out to clear glass. Carving & Shading: This technique is the third level of sandblasting. Carving and shading differs from etching and shading in that areas are sandblasted longer to generate three dimensional, sculpted effects. This process forms carved edges within the motif that appear whiter and brighter as they pick up and reflect surrounding light. With carving and shading, the sandblasted rendering looks three dimensional, as if it's floating within the glass.
