How hot/cold and what kind of container(thin/thick)? I use mine both in the microwave (heating) and the oven (cooking). They are pretty thick though, I bought them at Ikea.
In winter do I put them outside after cooking to cool down before storing them in the fridge. I have used them for 5 years without a problem. I have other cooking containers in glass too that is a lot older.
