Mine are stored as Lars said. The lid is on the pan upside down, And they are stacked. Always have the right lid for the pan that way. My Corning ware is stored the same way. Can't say as I've had any problems with breakage, either. So Dcarch must be right, about them being made of tempered glass. I happen to like glass lids. Have never had a problem seeing through them. Even when they are covered with water droplets, One can still tell how well the contents are simmering, Or sizzling, as the case may be. Rusty

I use both plastic and glass. I recently bought a bunch of the Premier storage containers by Rubbermaid, see the link. These are great, the plastic is hard and very clear so it's easy to see what's inside. The lids snap onto the bottom so when you store them empty, the lids are right there. I use the biggest one for a compost container on the counter, near the sink. The tight fitting lid keeps me from having any fruit fly problems. And the lids are flexible, that seems to make using them easier. I still have all my other assorted containers, too, but I ought to donate half of them to the thrift shop as I don't use but a few at a time. I also buy those shower cap type covers whenever I see them, we use those a lot to just save leftovers in the serving bowl. Here is a link that might be useful: Premier by Rubbermaid

Maybe I'm missing something, but I don't really see the difference between glass and plastic containers because the lids are all plastic anyway, including the lids of my glass containers. wintercat: I have always wanted some glass containers, but they are so expensive that I have never gotten any. I believe the difference is only that the container is glass and reheating something in it will not extract plastic residue since it is glass and presumably the lid is removed. I already had a couple of those old Corning Ware mini pans (and just found three more) to use for reheating small portions. Originally I had some plastic lids for them, but they were already long gone. Perhaps some will fall into my hands some day. Until then, I just use Saran Wrap or aluminum foil for storage. "The gaskets are of a hollow core and the OD of them are very them" What does this mean? olychick: my initial assumption (still held) is that a1an is a touch typist and meant to type 'very thin' and made a duel typo into 'very them'. Admittedly, I didn't originally see that it was an 'm' rather than the 'n' that I imagined was there, but I have often found myself typing a character from the same finger but wrong hand, and have done the 'm/n' thing as well.

Over the last couple of years I have begun to eliminate plastic storage of any kind from my kitchen. As things wore out or went missing, I turned to using my canning jars for storing things. As things evolved, I now use them for almost everything. They are great to store excess and to store leftovers. You can see everything in them, things stay very cold and the jars wash up with no residue left in them. I love them! My mom did this in the last years of her life. She had canned food out of her garden for decades and she had plenty of jars. As she got older, she had plenty of empty jars. The only problem is that now I am canning summer vegetables and my available supply is getting compromised. I have the little 1/2 pint size, to the quart size. You can even get them in larger sizes. Of course, there are some things such as left over pizza and ears of corn that need a differently shaped container. I keep a few things around for that, but mostly canning jars are what I use. I have also found that some cookware, such as covered casseroles, are great for food storage. You don't have to use them just to bake in. I will never buy any plastic storage things ever again. And, I will never replace any of them with new plastic ones. I even freeze in the glass sometimes. Although, it must be done with care with allowing room to expand and taking care when defrosting. As long as you know what you are doing, it works fine. I have a vacuum sealer that has an attachment to vacuum seal jars. That works very well for things that are time sensitive. I can also put a couple of fresh rolls or biscuits in the jars and seal them and they will keep fresh for longer. With the vacuum sealer, you can reuse the lids over and over, unlike with canning. As an added bonus I have rediscovered the joy of a "jelly jar" of iced tea in the summer. When I was growing up, that was what we used. These jars are so wonderfully versatile!
