Personally, No... I have not blasted ornornaments. The glass is rather thin, and the product is fragile. Again, I have not blasted them, but I have a customer overseas who etches the surface of glass bulbs for various shadow effects. I would imagine this would be rather similar. I know in their case, they use a very fine blasting media.
Thanks for reaching out to Rayzist....our films are Sandcarving films (requiring a sandblasting application). They are not chemical-resistant films. The resist will not dissolve from contact with acetone; it will begin to absorb into the film's surface and loosen, specifically at the design's edges.
Once the mask is exposed to UV Light, it cures (hardens) and cannot be made to be light sensitive again. Whatever is protected from UV exposure (black printed areas of the artwork/ "image") dissolves in the water wash, and you have a perfect 1:1 image transfer of your print. Great Question... Again, thanks for watching.
Blasting Media does not penetrate acrylic, like glass or stone, so it burns when you blast past the point of removing the polished surface. The key is to blast at low pressure and blast very lightly so as not to burn the acrylic (leave burn marks). Blasting acrylic is a technique. Hope this helps. Thanks for watching.
@@Sandcarving Thanks, it does look like a brown aluminum oxide is used in the video which might help with the staining. Currently I am trying this on polycarbonate at about 30psi with black aluminum oxide, but moving to the brown maybe even white oxide might help
Of course, they can be engraved from the front or the rear surface. You would have to reflect or mirror your artwork before printing your image transfer (artwork). I believe a "brighter" appearance, etching from the front, would be best. Unlike glass, for example, you achieve no 'etch depth,' so you lose the ability to see the perceived valve of Sandcarving. Thanks for watching!
Sorry, i have lots of questions... Have you sand blasted glass Christmas bulbs?
If so, do you have any videos on it?
I haven't found one yet...

Hi is the photoresist film resistant to acetone?

Once a film is washed, could something be added to it with the UV light, and washed again?

how do you prevent the aluminum oxide from staining the acrylic black?

Also, is the photoresist film stencil reusable? Thank you
Photoresist stencils are one-time use. There is no way to remove the film completely in tack and reapply it to another item.
How many cfm are you running at 20, 30 & 40 psi?
Thanks for getting back so quickly with my other questions!!!
Using our 3/32" Nozzle, your air consumption is between 5.0 - 7.5 CFM (20-40PSI)
Not sure if you are still monitoring comments on two year old videos....
Can these acrylic awards be sand blasted from the front or back????
