This is often confused with etching. Sandblasting is the process of blasting the surface of glass with grit which peppers the surface giving a milky white appearance.
This technique is used to obscure the view through glass but it still transmits light as it is diffused through the surface. Patterns and designs can be created using a mask which resists the abrasive force of the grit from the sandblaster. The mask can be hand cut or computer cut depending on the design.
Sandcarving is achieved by blasting away the glass for longer periods get layers of depth. It’s necessary to use thicker pieces of glass for this and the various depths are made by cutting away more of the resist each time. This can sometimes be a long winded process but is interesting for it’s 3 dimensional appearance.
If an image is supplied in a vector format then we can cut it directly using our computer aided cutter. Otherwise we have to charge to convert the image in the computer to vector lines the cutter can follow, this can also be a time consuming process if there is tonality to the image. It is better to supply flat graphic images in this case.
