Hi Paul -- my name is Deb Libby and I, too, had the request of a "carved" 
shower enclosure a few years back.  Luckily, I was remodeling my bath and had 
the old door to practice on.  I agree with "Glassman" -- it can be a 
disastrous!   Everything was looking great and I thought I had it just about 
finished -- I went to move it slightly for a better blast angle and the whole 
door basically disolved  into little pieces.  I was very lucky that it didn't 
explode -- it just shattered and then fell to the floor.  Unlike Arthur, I 
haven't dared to try another tempered/laminated piece.    If I did, it would 
be a very light surface etch.   Good luck.

Dear Paul,

I have told that the trick to this scenario is to sandblast standard 10mm
thick glass, and when the job is finished, take it to one of the bigger glass
manufacturers to have it tempered afterwards.

This is how they strengthen slumped or textured glass panels for use in
bathrooms.  All the slumping is done with standard glass and then the
tempering is done afterwards.

There is an interesting site on this subject which gives some guidelines to
the process, and is really a bible on the subject!:

I hope that this is of some help,

Dear Friends,

Someone asked me to etch a shower partition; 10mm thick, 600mm wide and
1.2mtrs high.  When installed, supported at the bottom edge and one vertical
side only (no frame).

My question is, if I use laminated glass, when I get as deep as the laminate
'sandwich' layer, will this resist the abrasive effect, same as the stencil?

and also...

If I use tempered glass, will the glass allow me to get that deep and then
once it's done, will the etched areas of the panel become weakened and
therefore dangerous to use in a public place because of the deep engraving?

The glass doesn't *have* to be 10mm.  What would you use?

Your thoughts and ideas would be appreciated, thanks.

Belated happy St. Andrew's day and bye from sunny UK,
