We use glass almost entirely as well - like others said, Pyrex and canning jars. I have had some jars crack when I've been too overzealous about removing them from the freezer (and putting them in warm water to speed defrosting
) so I just make sure to try to factor in defrosting time now.
We don't have a microwave. I bake in glass. We use stainless steel Lunch Bots or small Pyrex bowls for packing lunches.
Our dollar store sells glass storage bowls and lids in a couple of sizes we use frequently.
