Best way to laminate plate glass?

Was wondering what people thought might be the best way to laminate plate glass strips together to make a block-o-glass.  I will be sanding the edges with a angle grinder fitted with a flap disc, so a flexible glue would not be great.  Yes I know probably a belt sander would give me a flatter edge, but I am wanting a mottled sort of look.  Anyway, silicon is out, as it is not good for sanding  Epoxy might be the way, but I find it gets gummy under high heat friction sanding.  Gorilla glue maybe or is there some magic yet cost effective glue out there.  It will be a block about 2.5 feet by 2.5 feet with a thickness of about 3 inches.  It will held in a frame with continuous supports around the bottom and sides with the top 1 inch exposed, so it will not have to hold its own weight.  Double sided tape could conceivably  be used, but I am trying to make it somewhat water resistant.  It doesn't have to be clear, but it does have to allow some light transmission.  Enough caveats on it?

You want to laminate glass and grind it, but you don't want the heat of grinding to heat up the glue and cause a melted plastic situation which will clog the grinder, right? Then try-

Spray adhesive like the kind artists use.
Egg whites thinned with rubbing alcohol.
Fuse the glass in a kiln first.
Any of the glues or epoxy which you don't like grinding for their "plastic" properties- BUT, use a wet sander just as you would, or should, on glass.

The egg whites intrigue me... Love to kiln fuse it, but... the closest kiln for glass I know if is about 1700 km away. Curse of living up north in the middle of nowhere. Though about milk glues as well.

Water glass!
It is-
"water glass (also soluble glass): a hydrated sodium silicate, Na2Si4O9.xH2O, either an amorphous solid or in thick aqueous solution, used as a binder or adhesive."

Ref. http://web.lemoyne.edu/~giunta/archems.html

Sounds to me like sodium silicate could be ground without gumming up. (I have not tried this yet, your mileage may vary.)

If you just want a block, oil (e.g. Johnson's Baby) would hold the sheets together, if you weren't needing it to resist lateral-forces.

Interesting, but my wife would kill me as its going int he living room! The way how it will be used, leakage would most likely occur!

Very small amounts of liquid can "stick" glass quite effectively, but I'm thinking of water first.

oh yes, when i brought the glass back from the dump where I found it, a lot of it was stuck together just with tension of the dew between it. I actually broke a piece separating it.

That is what I was thinking.

Plus i might be nervous with the idea of it ever shifting. It will be in close proximity to potential skin contact. One little shift could expose a 2 1/2 foot long razor blade, youch!

I think in a couple weeks when life calms down.... I'll try a variety of different styles suggested here, tack it into the instructable and post the results. Thanks everyone!

Wonder if a Halloween fluorescent black light would have enough UV output.

Are you doing an ET communications device?

Pardon, I have not a definitive solution, but I suggest you use car putty. It is not clear, but in very thin layers it is translucid. Maybe there is another similar. Have you tried epoxy really? I think it does not get gummy when heated, try it.

No on the ET, but almost as interesting. Sadly, i have with the epoxy. High speed rotary tools do make the epoxy behave in a almost molten plastic nature. Ever cut plastic barrels with a jig saw, if you go to quickly the plastic fuses behind itself. In this situation i wouldn't want to be scraping re-hardened epoxy off potentially jagged glass. Accidents like that practically beg for me happen

Silicone sealant? It is used for make glass fishbowls.

UV curing glass glue ?

I have read about that before, the surface area I want to glue together is close to 90 sq. feet. Might be a little pricey. Trust me, all my instructable are on a major budget. My interactive LED table, about 30$ to make. Animatronic hand 19$. I can be very crafty and resourceful when creating, but certain chemical items you just can't get around the price. I thought perhaps polyester resin, but that is more of a mechanical bond...

Would sodium silicate - waterglass - do anything ???
The traditional optical/glass glue was balsam, which is made from pine trees.

Yikes, yeah probably the best thing, but way, way out of my budget. Just checked, : O
