Thinking about getting rid of the Rubbermaid Serve'n'Saver food storage containers we now have, and switching to glass. We also have a bunch of the Ziploc two-cup round containers with the screw-on lids that I use to freeze portions of stock and soup in. Although they are all either #5 or #2 plastic, I'd just feel better about using glass.
The 3 main choices seem to be Luminarc (Arc International), Pyrex, and Snapware's GlassLock. I do have 2 of the Glasslock containers (one is to store fresh vanilla beans, the other for feta cheese) but of course the downside is that they're not stackable like the plastic ones are. Also we have one of the plastic Snapware bowls that gets opened daily and I see after a couple years of use that one of the lid "tabs" is starting to split away from where it attaches to the lid top so maybe they all do that?
I like that the Luminarc line is made in the USA (glass in USA, lids in France) so that's a plus. Likewise Pyrex is USA-made. Not sure about the GlassLock although interestingly I see on the Glasslock website that the parent company is called Eco Housewares dba Dooit USA. If you read the "About us" page it's clear that this was not written by someone fluent in English, LOL. So I do wonder. Also if you read the small print on the main page, GlassLockUSA is not the manufacturer; they are only the USA distributor of the product. So my guess is that these are probably made in China.
I know the lids on the GlassLock are the easiest to operate (IMHO) and have the tightest seal BUT I have read user reviews that say the tabs don't hold up well to freezer storage so am wondering about that.
What has been your experience with these 3 brands for glass food storage re: these specfic factors:
(1) Ease of closing and opening lids
(2) Airtightness of lids, particularly with liquids
(3) Stackability/space saving storage of the empties
(4) Going from refrigerator directly to microwave (since freezer-to-micro is definitely a no-no)
(5) Materials issues (lids cracking or splitting, glass cracking or shattering, etc)
(6) Whether the plastic lid tends to hold any odors from prior foods
I would never use any plastic lid in the microwave (I put a piece of waxed paper over the container top instead) so that performance is irrevelant, btw.
Thanks in advance!
