Call it whatever you like but it's wrong in the Auto industry. It's either 1. laminated or 2. it's tempered in the auto industry . those are the 2 processes that the auto industry uses. that's it no other as of 2007 when I retired fully.
Now in the Housing industry there IS a "safety glass" but it's just faster annealed (cooling) glass that is safer to work around and you CAN cut,drill,grind on that ......Heat-strengthened glass is made by heating annealed glass uniformly, then cooling it at a slow rate. The rate of cooling directly affects the strength of glass. The regular process of cooling – or annealing – float glass results in a slow rate. Stronger glass can be produced by changing the rate of cooling. Heat-strengthened glass is about twice as strong as regular annealed glass of the same size and thickness.
I read the article. (problem is I was working in the glass industry for over 30 years(1968-2007) and saw that Misconception everywhere EXCEPT in the Automotive glass industry) it's in the safety industry, it's in the Architectural Industry it's in the insurance industry also even common glass repair shops like safeguard use it, it's an automotive buzz word making you feel good. But if you work in the auto glass industry it a stenciled label put on by the designers like safeguard safety glass,PPG glass(not a safety glass, but tempered no matter what the labeling says) . The only label that matter to the glass guy(oh and the safety DOT guys and to your body in case of an accident ) is the A,S or M codes and the numbers or the European E in a circle (they have a tighter break pattern then the USA, that's it you could label it "dog doo Scooby Doo glass" and it'd still have to have the A,S- M codes as in A1 or AS1 or M60-m69 AND still pass inspection by the DOT. We ran the neon side glass for a year with the reversed lettering since that is the way the engineers designed the label before someone read the complaint about it being backwards and had a new program made for the lasers (idiot engineers thought the laser was on the bottom firing UP towards the glass when it was on top firing down.
