Quoted from leonml:The whole warm hands shattering cool glass scare is a bunch of dog poo. There's not a set of hands warm enough to heat even the coldest piece of glass fast enough to cause it to just shatter from rapid molecular change. If this were the case, no glass ever made from the beginning of time would hold up in cold winter months. When your car heater was blasting on the windshield, before the days of tempered or safety glass. They're are model t fords from wisconsin with the original glass. Also there'd be a ton of fishing and hunting shacks and old houses with hand formed glass windows laying in crumbled piles outside every building in wisconsin and other. Cold winter mornings at freezing Temps and that hot morning sun is hitting it directly at much higher temp, no breakage. Could go to an old hunting or fishing shack or cabin, below zero out, start a wood fire, rapidly heating to room temp and even with the extreme cold temp hitting the outside and warm heating the inside, you could tap it or have a small branch or bird or whatever hit that glass, no breakage.
Only way I see backglass breaking is poor handling. Maybe handling the very edges of opposite corners, and holding it parallel to the floor, possibly walking with it could cause the glass to flex and the corners to break off, then shattering on the floor.
Otherwise the physics would negate otherwise.
I've had old games in a garage that was 20 below zero, brought it in my house at 73 degrees, and handled the glass and no breaks. I've hauled and unloaded games in that kind of weather and brought them inside, hauling down stairs, jarring every step down, then unwrapping, setting up, handling the glass, checking everything over, and no breakage. Yes I waited to turn the machine on after a couple hours.
Just my 2 cents worth. Supported by science, physics, logic and real life examples that can't be refuted.
you do realize that model T's don't have tempered glass right. There was no such thing as tempered glass back then. Tempered is strong as shit, unless it is subjected to temp changes (no it doesn't take that much of a change) or you slightly ting one of the edges. Have you watched the video where someone shows you how durable playfield glass is? The guy stood on a piece that was on bricks from side to side..bounced in the center. Didn't break. Barely hit the edge with something and it shattered into diamonds. It's just as fragile with things cold or warmer than the glass. Anyone around here can tell you they have seen it first hand. No mishandling..nothing. Just bursting in your hands for no reason. But this only holds true for tempered glass. Many EM glasses and zaccaria glasses are standard glass and are not as fragile to these conditions.
