Sandblasting etching is a technique used to create intricate designs in glass by directing abrasive sand onto the surface. The process involves selecting the material, preparing the surface, and using a protective material to cover the rest of the surface. The sandblaster nozzle is directed along the lines of the design until it is recreated on the glass surface. The results can be breathtaking.
Sandblasting etching refers to the method of using sandblasting to make purposeful etchings or marks into materials, particularly glass. While the sandblasting process can be applied to other formats or materials, such as stone, it is more often used to create intricate designs in glass. The utility of sandblasting for surface preparation purposes comes from the abrasive nature of sand, a material that has grainy attributes and is also of the right size to be applied to desired surfaces via equipment that drives the sand onto the material it is directed at. This abrasiveness can be used for decorative purposes through the deliberate manipulation of sand at particular points on the surface of the material being designed in such a way as to allow the design to take shape.
The first step in sandblasting is selecting the material that will be used for the crafting. The person who wants to use the etching sandblasting technique must have formed a concept that will be the basis of etching sandblasting, in the sense that it will tell him how to direct the sandblaster nozzle. Some people like to generate a concept using design software or simply drawing something on a piece of paper to serve as a visual for the sandblasting and engraving process. When the design concept is ready, the surface of the material to be engraved will be prepared, depending on the type of material. In the case of glass, the surface can be cleaned with a specific cleaner for this purpose.
Other preparatory practices include using a specially selected material to protect the rest of the material surface from abrasive sand particles. In the case of glass, a special paper will be used for this purpose to cover the work surface and the design will be either computer printed or hand drawn and placed on top of the protective paper. The sandblaster nozzle will be directed along the lines of the design on the printed paper until the concept is recreated on the glass surface. When sandblasting is done in a controlled way, the results can be breathtaking to behold.
