Sandblasting safety glass?

[Carla]

I'm sure this has been discussed but I couldn't find it in the archives.

We have a glass cabinet with safety glass set in it. I want to sand blast a design on it.

I thought I read somewhere (or not) that the blasting might compromise the integrity of the glass and it will break?

Are there any problems with sandblasting safety glass I should be aware of before I have at it?

Thanks

2 kinds of glass can be classified as safety glass, tempered and laminated. chances are that you are dealing with tempered. There is usually an etched mark denoting the specifications the glass meets and which manufacturer did the tempering.

It goes like this. You can surface frost the tempered glass with pretty good chances for success. If you should blast deeper than 10% of the glass's thickness, it will explode. Blasting the surface can eliminate 1/2 of the strength gained by tempering, but there are no codes prohibiting this treatment.

Laminated glass is simply 2 panes of annealed glass stuck together with a plastic interlayer. You can blast it.
