View Full Version : Sand Blasting Wedge of Crystal?

I have a “vertical wedge” of crystal to sandblast a large amount of text and a logo onto.
Reverse engraved optical crystal is stunning, especially when using multiple layers. The problem I have is that I am not sure about reverse engraving a “wedge” in case the text etc is distorted when read from the front surface which is at an 80 degree angle compared to the rear 90 degree (vertical) surface. The base is 30mm deep and the top 8mm deep.
Am I imagining a problem that does not exist? What do the rest of you do?
Thanks very much, John

I think you are imaging a problem. Print it on paper, put it behind it and see how it reads. I don't think it's going to be any issue at all.

It will be fine. I have lasered/sandcarved, and UV printed quite of few of those.

Is your concern about how to level the surface so the item will laser flat. Or the optical effect of looking through a glass surface..

Hi Mark, it was the possibility of optical distortion. I have done the masks now, so will sand blast this afternoon.
Thanks and regards, John
