Lucky mate

If it had landed on the edges first, you would have had a hell of a mess to clean up. Better a pf glass than a backglass!

you are lucky! very lucky

I have heard that just setting a sheet upright on a cement floor, and the slightest contact of the cement with the edge is enough to make it explode.

I would bet you could let one fall over onto a pinball on the floor, where a normal piece of glass would break, and a tempered sheet would not.

...hmmm I have like 12 sheets of scratched glass I need to get rid of, I should do some youtube testing

I've had this a few months ago...I took the lockdownbar out my WH2O and while I wasn't looking, the glass slides out of the machine on the ground. The glass wasn't broken !!!

Thank goodness you avoided a tragedy. Never against a door. Are we going to have to send over Mr. Towelie to lecture you on the proper use of towels? He roams the country providing proper towel etiquette but I believe he recently settled down in Colorado for some reason.

A little off topic, but mentioning the scratched glass makes me wonder if the Invisiglass scratches and easier or less often than normal glass. I've thought about buying a couple of sheets but have to bring myself to do it.

Similar th
Ing happened to me with playfield glass - it got tipped over in the garage and landed on the concrete without breaking. I felt pretty lucky that day!

I have toured a window making co. and on the assembly line,
huge 5' x 5' sheets of glass are standing on edge and an arm
picks the 1st sheet in line and pulls it over just enough for it to
drop/fall over onto a table. The table is layered with hard rubber.
In the rubber are small holes with air coming up through them.

It's probably the same idea as what happened to you, the air cushions
the fall.
Now understanding you didn't have air blowing up on the glass,
these are also HUGE pieces of glass falling over.
Amazing thing to see.

I had the same thing happen to me the other day! I was fixing the dop targets on Pinbot and had propped the glass up against another cabinet, when my attention starved cat decided it would be cool to rub his face on everything in the basement...including the piece of glass. My back was turned as I was hunched under the playfield but I heard the loudest CRASH! I turned to see my cat tear-assing out of the basement and the piece of glass on the concrete floor...perfectly fine. Whoa!

Yes, it will scratch more easily than regular glass, as it's coated. See this thread:

In general you get best optical properties from glass that's coated for the application required, but the coatings are generally more delicate than a hunk of glass is. (I work in a laser lab.)
