Question about tempered glass

I'd like to use a piece of tempered glass from a section of deck railing as an office chair mat.

Is this possible? Is all tempered glass (e.g. from furniture, shower stalls, deck railing, chair mats, etc.) more or less the same in terms of hardness and durability?

If u nick the glass, it can eventually shatter

tempered glass is very strong if you stay away from the edges, you can walk on the stuff, Ive seen people do it on greenhouses, not myself though
if the edge gets a little crack or hit with even medium force it will shatter, thats just how the stuff is made, we've broken pieces at work trying to replace a smashed one and the new one breaks just from the installer trying to force it into its place

Those applications are fine as there is no weight on them. If you floor is absolutely unequivocably flat and you stay away from the edges it might work...if there any sort of non flat spots/voids, applying force on a small area, it can shatter .

If you look at window glass...you can hit it with your arm/foot and it won't break easily (force is spread over a bigger area) but if you take a "pointed" object and apply force it'll shatter.

Failure is always an option...just not the preferred one!

I saw a thing on reddit recently where a life hack was to use some laminate flooring from a place like the restore as a chair mat for a desk.

As a window/door guy, I would not put uneven weight on a piece of glass designed to be vertical in the horizontal position.

Think structural glass instead. Google it. But be forewarned ... $$$.

Someone posted a review of a tempered glass chair matt on Amazon. Everything was going well until they dropped a small metal jewelry stamp (about 3 ounces) on it. Shatter city.

On the plus side, the Amazon price was $120 for a 36”x46” matt.

My question is, why?
Buy a nice thick piece of Lexan if you want a transparent effect. You won't have to pick up ten thousand glass bits when it inevitably shatters. Or buy a piece that's double laminated like windshield glass. Easier to clean up when it inevitably shatters.

Lexan is more expensive and only 2.5 mm thick. Is it harder than tempered glass?

Lexan will mar and scratch easily. Laminated glass will break when you go to sit in your chair. Tempered is your only option but I wouldn't recommend it. I know it's strong but all it takes is a nick to break the compression. I've stood on one inch thick tempered over a span of 8' and it held.

Tempered glass will shatter if it’s hit wrong, and it doesn’t take much of an impact to do that. As I posted previously, a 3 ounce metal weight dropped off a desk can do it. Lexan would be much more resilient in that regard.
