as far as i know, pyrex storage bowls are just regular glass. it doesn't leach and it doesn't absorb. it's chemically inert.
i have around 25 of those bowls and they are the best darn purchase i ever made. we use them for eating in, baking, storing, marinating - absolutely everything! in fact i am eating out of one right now. :LOL the great thing is once it's been washed, you'd never know what was in it previously, unlike plastic. just the way i like it.

you won't regret your purchase! the bowls once kept some washed lettuce fresh and crispy for 6 weeks (in the refrigerator). i couldn't even get the same results from my fridge's own crisper/humidity bin.
just a little note: some people find that they arn't liquid proof, so you may want to take that into consideration if you plan on using them to store soups to take to work. personally, i have never had any liquid leak from them. i hand wash the lids.
if you want to store dry goods (or any foods for that matter), canning jars are also excellent. they are all glass, airtight, inexpensive and they look nice in the kitchen pantry too. i use the arc canning jars for storing chickpeas, lentils, rice etc. they keep the food very fresh for a long time.
i also have corning visions stovetop glass pots and pans and they rock! another great purchase. you can only find them on ebay now though. i cook and store in glass only.
i



glass! can you tell?

i'm curious as to why you think corning is bad?
