Steps for Sandcarving Glass

Here are some basic steps to sandcarving glass with a two stage sandcarving method.  It is just one way to etch glass.  You can see some of the popular ways by going to the main glass etching page.  If you have read my ebook or read through the site, it discusses this as the major reason to use a pressure pot sandblaster.

Sandcarving

Through a series of sandblasting stages, you can carve a 3 dimensional shape into the glass.  This is very basic and can get more advanced.  If you would like to know more about the advanced ways, please leave a comment below.

So here are the basic steps to sandcarve glass with a sandblaster.  It is a simple 2 stage sandcarving.

First, place your stencil on the glass and cut out the pattern with a knife by following the lines.  This example is with a flower that you can download for free at the glass etching pattern page.  You will need to observe the stencil design.  As you can see, I marked areas of the cut stencil with numbers.  the number 1 means its the first blasting and the deepest to be carved.  The number 2 means its the second blasting and is a light etch.  Remove the number one areas of the stencil or the areas that would be closer to the observer when looking at.  The picture below shows the first sandcarving stage ready to be blasted:

Below is a picture of the first stage deeply sandcarved with a pressure pot sandblaster:

After you have sandcarved the glass deep, then you can begin peeling back the stencil for the number 2 stage.  Remember, you can mark the areas with a sharpe marker like I did.  I marked the stencil areas with the number 2.  As you can see, I pulled the areas and its ready to be lightly sandblasted below:

Then, for the final step after the second stage was lightly etched you can remove the stencil resist and clean up.  Since I did a reverse etching which is the best way to sandcarve glass, you will need to flip the piece around as shown below:

Update: Some people have been having problems with photo resists and stencils coming off so I made a post about fixing photoresist blowout problems.  I hope these tips will help.  Feedback would be great, just leave me a comment!

    Nice job on the flower Eric. Keep the beginner projects coming. Another tip on the 3 mil photoresist is to keep the nozzle moving. Never linger in one spot as the resist heats up quickly and will fail.

    I appreciate the comment Glen and thanks for the good tip. I think in the other blog post, I explained how you can sandcarve with 3 mil stencils. The key is to use a finer grit. The stencil used above was a 3 mil resist made from my cutter. I used 180 grit on it and I can cut fairly deep. I know it sounds ridiculous and maybe unsafe or unprofessional, but it works. Thats one way to get around the expensive thick sandmasks. And since I was going to use the finer grit no matter what, it works out. A finer grit makes nicer etchings.
