Transitioning glass from one extreme temperature to the next may cause stress to the glassware item and could risk breakage from thermal shock.
To avoid this, we have a little bit of advice. Try not put hot items in cold glass. If you have just rinsed your glass in cold water or it has been in a cold location, pouring hot tea, coffee or placing other heated items into it can cause it to stress and crack. This works the other way too- just be mindful to only expose your glass to higher or lower temperature when it is already at room temperature.
