Strengthen cracked glass panes, how?

Bought a stack of assorted large (4’x2’ or so avg.) NOS glass panes made for industrial applications, some single pane, some like auto glass, some wired inside, etc. Why exactly that heavy pallet dropped about 6” is too hard to explain, but it did, I did it, and some of the glass is now cracked, but none has bent or relocated due to its robust design. But I’d like to reinforce the cracks somehow, appearance when done doesn’t matter, I’m going to install it on a steel fume hood that’s about 12 x 5 x 8 ft., and has a 10’ x 42” hole along one side for windows to admit light and reduce claustrophobia of workers inside. So as long as fixed glass is still translucent it is fine. I think cracking is limited to a few pieces and at the outside of those. Epoxy? Superglue? Some proprietary stuff? What would you use? I can post pic of fume hood if u want, no pix of glass yet.

 

I would suggest going to one of those shops that fixes windshields.....they put some sort of "goo or glue"....totally transparent....so they don't have to replace the windshield if it's like from a stone.....it seems to stop it from growing.....ask what they use!!!!! Might be something pretty simple too!!!!

 

clear gorilla tape.....it's strong..

 

Thanks, I finally got the glass fully unpacked and only one sheet out of about 20 was cracked, and all over too so unrepairable. I dispatched it with a hammer so it’ll fit in the trash; was double auto-type glass so was very hard to break up. The rest is 1/4 in. thick wire-reinforced glass so I think it’ll do fine as windows for the large fume hood. We’ll put each pane into a wood frame sort of like storm windows so they’ll be easier to handle and install than just glass panes. I have to look up wired glass and find its characteristics, never had any before. There’s a supplier’s description with it but it isn’t too detailed. But maybe it has all details needed, it is described as “wired safety glass” made of “super lite I-W.” Articles on the web say that type is used as safety glass because it has good fire and impact resistance.

 

that type of wire safety glass is used for openings in fire rated walls and doors. the size of the glass determines the overall fire rating of the wall; generally the smaller the glass size the greater the fire rating.

 

Thanks. Remembered I’d taken a pic of the tag that was on the biggest piece of that wire glass:

 

When I was selling sheet glass PPG called this "Misco". LOF had it own version and name. The wire was embedded in the glass when it was made. It was basically a safety glass in that when broken it did not shatter and allow bad people to come in. In the mid 1950s fire rating for these was not so important. You could cut it to size but the sharpe edges required a frame.
