I have some easy snap lid glass containers from Costco and they say you can microwave them but dont heat in oven.
I know you would take the plastic lid off but what is the big problem here people? Is the glass going to explode .001% of the time? Will it ooze dangerous toxins into my food?
Unless I get some good concrete reason why I cant heat the glassware in the oven I am going to try it.
I suppose I should call the maker but you folks are just as good as them I bet.
