Interesting discussion altho they are all talking about their microwaving. If you are serious about your health one of the first things you do is unplug the microwave. The Q & A however at the end is excellent altho they question visionware which I've never seen in many health discussions that I've read. The sources I've read place toxic metals at the highest of priorities to eliminate and the plastics and polymers at significantly lesser priority.

Another nice perk to the visions corningware is that you can cook, bake and refrigerate your food in it so it is very versatile. Yes, you can also microwave in it too if you still do that.

What I will usually do is make a pot of soup in the 4.5 liter, eat about 2/3 of it, put the lid back on and put it in the refrigerator. Then the next day I will take it out, let it stand for a while to acclimate then heat it right up in the same pot. I don't usually like to eat leftovers at all as leftovers aren't as healthy as freshly cook but what the heck, nobody's perfect.
