It’s not cultural: the ridges help the glass stay strong and resist temperature variation better while keeping the glass as thin as possible for better temperature transfer in the fridge.
how can it resist hot temperature change but be better transfer for becoming cold? the thermal transfer coefficients are the same, no? if it gets cold we’ll in the fridge then it should get warmed up just as well when left out

By resist temp variation I assumed they meant not cracking
good point, thanks!
