This sounds daft, but I've been given a nice set of wine glasses which are made of incredibly thin glass, and tonight I bumped one against the cupboard door and to my surprise, it didn't smash. This got me thinking, how could I tell if they actually are glass? They don't feel like plastic, and they 'ring' when I tap them, but they're much thinner than all my other glasses. Any theories anyone?

Would scratching do it? Perhaps plastic, if scratched with a pin (or whatever) would be damaged and glass wouldn't. Just an idea!

If they make a ringing noise then I'm about 99% certain that they are glass. As for it not breaking I've dropped glasses before and was suprised when they didn't break. Luck?

Glass feels cooler than plastic, get hold of a plastic cup or tumbler and if it feels different then you'll know for sure. They're probably lead glass since they're slightly harder than standard ones.

wet your finger tip and run it around the rim of the glass, if you hear this sound, like when somebody plays a saw, it is glass and it is probably crystal also. plastic doesn't "ping" when you tap it. Gently tap it against your teeth that will tell you too.

Buy your stemware at a reputible place.

Temperature -- glass holds its temperature more... Compare the feel of anything in a glass jar the fridge to something in plastic... Glass feels cooler than plastic. Or hotter if just out of the dish washer...
Ring 1 -- "ping" it with your index finger Ring 2 -- holding the stem (not bowl) "clink" two glasses. If they ring nicely they are glass, not plastic. Add a liquid and repeat... The tone will change. As for not breaking... Well there is "unbreakable" glass. Also glass you can cook with on the stove... Test tubes are made of glass and are indestructible, etc. etc. And if they are very thin, the manufacturer has probably used a tough glass to make sure that they do not break when "bumped" as in toasting... And a little bump on the cupboard door would not really be a "destructive act" even with ordinary or more fragile glass! |

Heat up a tiny pin and stick it into the side or base of the glass, if it melts and goes in, it's plastic.
I would almost guarantee they are glass, probably Riedel or Spieglau, 24% lead crystal, and the way you bumped the glass was at just the right angle to diffuse the impact, otherwise, it would have broken.. |
