How to tell if your tank can be drilled?

I understand that tempered glass panes will show a pattern when viewed with polarizing lenses. Or you can scratch it... tempered glass shatters when the tension is broken

Sweet, I think there is a small scratch on the glass. That should mean it's not tempered then? I also have a polarizer that I can use to test it. Thanks for the tips

Polarizer should work. But any new tank over 50g usually is tempered. Also if the glass looks thin for that size of tank then it is probably tempered,

Not at all tempered glass can be scratched. What's the size and brand of the tank?

Hmm, okay I was told a while ago that when scratched it will shatter or spiderweb. I guess I was misinformed, sorry
