ok so lets say in your car you can blow hot air on the glass with snow on top and be ok but if it has a chip it will help the glass to pop or crack. If the tank is made with glass that has a lot of chips under the black plastic it will help the glass to pop. I have seen a few pics on google of ppl with glass tanks for a bp and they have the heat light half over the tank so the side is geting heat on it. Now yes you can keep a bp in a glass tank and I may be wrong but the op posted asking what the bid deal is. So to me they are asking about it all /hot glass/glass cracking/humidity/heat transfer/cleaning/and so on.
Man your kinda reaching. Let it go man just let it go.
