Guest 32stude Posted January 6, 2015 Share Posted January 6, 2015 Just purchased a 1932 Plymouth PB coupe that was restored in the 1990's. I'm trying to determine if all the glass is saftey glass. The glass is not laminated. Is it possible to have safety glass that is not laminated ? How can this be determined? Thank you for your help.32stude Link to comment Share on other sites More sharing options...
Restorer32 Posted January 6, 2015 Share Posted January 6, 2015 It could be tempered. Unlikely though since such glass has to be cut to size and sent out for tempering. Tempered glass can't be cut. Sounds like you have plain plate glass if you are sure it isn't laminated. Link to comment Share on other sites More sharing options...
Larry Schramm Posted January 6, 2015 Share Posted January 6, 2015 Generally speaking, all windshields are laminated safety glass. The rest of the glass in the vehicle would be tempered safety glass. Here is some additional information on glass. http://www.secondchancegarage.com/public/windshield-history.cfm Link to comment Share on other sites More sharing options...
cahartley Posted January 6, 2015 Share Posted January 6, 2015 Tap on the glass with your knuckle.If it's safety glass it will "thud"........if it's plate glass it will "clink".Have you ever seen how plate glass breaks?....... :eek: Link to comment Share on other sites More sharing options...
Rusty_OToole Posted January 6, 2015 Share Posted January 6, 2015 I think by 1932 they came from the factory with safety glass. Is it not marked in the lower corner or was that something they did not do in 1932? Link to comment Share on other sites More sharing options...
Friartuck Posted January 10, 2015 Share Posted January 10, 2015 Try the coin test. Hold a nickel with the edge on the surface at a 30-45 degree angle away from the surface. If its safety glass with two layers, you should see double reflections. Link to comment Share on other sites More sharing options...
