Sandblast etching is one of the most elegant processes that you can use and my favorite processes. This tutorial shows the basic steps.
- Follow the first 3 steps just like the cream etching method by creating a stencil resist which was discussed before. In the example shown, I chose to etch from the backside of the glass. To do this, I had to reverse the image in the software by using a “mirror tool”. Overall, the other steps are relative, but the only difference is that you may want to use a thicker resist material if you are engraving deep into the glass. Also, I masked all areas outside the glass to prevent over blast.
- Second, you need to take a sandblaster and blast the exposed areas of the stencil resist by abrading with a constant back and forth motion.
You can see, I use to used a deadman sandblaster valve which I don’t recommend. I now use some cool stuff that is both inexpensive and works great in the members area.
Each stroke should be overlapped about 50% to evenly etch into the glass.
- Once the glass is etched to your desired depth, you can peel the resist stencil off and clean up. You can use your Xacto knife or tweezers to pull the pieces off.
I found that rinsing warm warm over the stencil for a majority of materials helps make this step very easy to do. You can either rinse the water over the stencil or dip it in a tub while removing it.
- I turned the finished piece around so it’s looked at from the other side. You can choose either side to etch, but just make sure that you “mirror” the design first in your software. If you’re sandcarving, you will want to etch it the same way I did here.
