The Pressure of Sandcarving Glassware

Determine the right blasting pressure.

As you think about how deep you want to blast, keep in mind what you are blasting on: glassware requires less blasting than you could do on an award blank that is at least 1/4″ thick or as much as 3/4″ thick. When it comes to blasting either object, you also have to choose your pressure settings on your blaster. For glassware, in general you should set your blasting pressure on your pressure pot to about 20-25 pounds of pressure.
