Here are the characteristics that I will list, positive and negative for both sandblaster types talked about before. Remember one of these are required when you are sandblasting glass for advanced techniques. For this post I will explain the siphon sandblaster and its characteristics for abrasive etching.
Siphon sandblaster- The siphon sandblaster setup has an air hose that connects the air compressor straight to the nozzle. Another hose is connected to the same nozzle that carries the abrasive particles. It basically works by siphoning the abrasive out of a container and thrusting it out the nozzle.
- Positive Characteristics: This is the cheapest sand blaster setup. The major advantage is that some are manufactured with a nicer nozzle setup that allows better control to do advanced artistic techniques such as shading. The nozzle allows a variable flow of abrasive and air mixture with a slight move of your fingers on the trigger. Not all siphon sandblaster nozzles have the variable pressure feature, but isn’t needed for basic etching.
- Negative Characteristics: The siphon setup doesn’t have as much blasting power, takes a longer time to etch the glass, limits the possibilities of multi-staging & sandcarving, and uses more compressed air to operate. Another disadvantage is its inability to keep a consistent abrasive flow. It is less efficient than the pressure pot sandblaster which doesn’t usually allow the ability to do multistage sandcarving.
