airbrush cleaning pot; not sealing cos GLASS is warped?

Yes the glass, not the lid. Has anyone else seen it before? Got one of the small ones from ebay, generic version of the Revell branded and Iwata branded cleaning pots. This one;
Airbrush Cleaning Pot (Vallejo 26005, No)

After a few months noticed it was venting vapour from the threads of the lid, and one day the lid came clean off. under inspection, noticed that the glass itself was deformed around the lip and threads, so much so that it wont screw down at allmnow.

Bought one of the larger yellow lidded ones from Bartsharp.
Airbrush Cleaning Pot (Fengda BD777A, No)

Big conical shaped one. Turns out to be too big for my spray booth and as well will not hold my Aztek safely. After a few weeks noticed the very same issue. Lid is fine, but won't screw closed as glass is warped. Am I just unlucky or does a combination of IPA, white spirit and cellulouse thinner cause glass to melt? If the plastic lids did I'd understand, but the glass? Has anyone else seen this before? Or am I going mad?
