Chemically toughened glass can bend and not break.
Anyone know about this type?
Like a lot of things the discussion is a long but interesting one.
All Glass strengthening relies on a similar principle - glass (like concrete) is strong in compression and weak in tension so in order to strengthen one creates a surface layer that is under tension (similar to pre-stressed concrete).
In order for the piece to break you have to first overcome the surface tension before it will break - but when it does many characterize it as an
explosion" - it is in fact a release of that energy that is build into the part.
The weak point in Strengthened glass (any - chemically, tempered, etc) is the edge so you have to be careful when mounting - any point loading has the potential to cause a break. Best practice is to make sure there is clearance all around - use shims if necessary when mounting to center the piece and fill the void with a flexible sealant.
Generally chemically strengthening - which is a surface treatment - is best used on thin sheets. Heat strengthened (tempered) glass can be used on thicker pieces. Generally speaking chemically strengthened pieces are high volume production and the process doesn't lend itself to one-of-a-kind specials.
Cell phones, tablets, some flat panel display (PC, TV's) also have strengthened cover glass.
Ever hear about Gorilla Glass (TM) that's Corning Inc's chemically strengthened glass for cell phone, tablet, display, etc applications.
This came out of an effort back in the 1960's to produce chemically strengthened automotive glass - a market failure at that time but the basic process is back for above uses and it's creaping back in into the hi end auto market.
I spent a career working for Corning Glass and actually made hi performance aircraft windows (B1-Bomber) from chemically strengthened glass back in the 70's and tempered windows for the space shuttle...as well as many other interesting products & projects.

A Day Made of Glass 1 & 2 - pretty interesting stuff - this is all possible today not furturistic sci-fi stuff.
No doubt more than you expected - be careful what you ask
Edit: Laminating doesn't add significant strength but it does prevent pieces (shards) of glass form becoming projectiles and causing injuries - hence the use of laminated glass in auto windshields (and the frequent breakage /repair / replacement of windshields)
