Glassware not safe for ovens?

post #1 of 3
Thread Starter 

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.

 

Thanks

Glass tends to handle the stresses of higher heat environments badly. It can explode if heated/cooled unevenly which is surprisingly easy to do.

 

There are specialty forms of glass such as Pyrex that behave better for these purposes.

 

As to glass in the microwave, it generally wont' get hotter than about the boiling point of water. But if you were heating something greasy, or sugary, you may be in for a bad surprise.

That make sense, I forgot about Pyrex.  I was not thinking well.  Thanks
