Honest question: Why do you try to replace Tupperware?

Plastic has a bad reputation because of its longevity, but that also makes it a good material for containers. That - in turn - makes it bad for throwaway packaging of course. I might have missed something, that's why I ask.

There's definite leaching of plastic compounds into food, which gets exacerbated when heated. My concern is the number of unknown unknowns. BPA became a big part of the consciousness a few years ago, and now it's PFAs, but what else?

My general view is that glass is super-durable, microwave-safe (I would never microwave Tupperware), and the cost tradeoff is minor, so it seems worthwhile. That said, if I order takeout and it comes in a plastic container that's hot ... I still eat it :).

PFAS and BPA are not used for (multi-use) food containers I think. Don't get me wrong! Avoiding throwaway packaging, where possible, absolutely makes sense. I specifically mean to find the culprit with Tupperware (or multi-use plastic food containers in general).

Glass breaks faster than plastic containers (usually). I still use glass containers, but I am always aware that they break relatively easily.

Regarding microwave-use I am with you. Not a fan of microwaving plastic, even if it is safe for many plastic materials (the term plastic is vague I admit).

I have maybe 60-70 or so glass food containers that get very regular use from being used for leftovers, to being put in the deep freezer for 6mo and then warmed up.

We handle at least half a dozen of these a day on average from filling/cleaning/removing portions and putting back into the fridge.

I've broken dozens of the plastic lids for them. I can't remember a single case (although I'm sure it's happened) of breaking a glass container in the past decade. They have survived more than a few rather large drops. These are the Pyrex brand glassware with the new glass that is more drop but less heat shock resistant.

Luckily Snapware also sells lids, since the glass containers far outlast the plastic lids and we end up replacing 3-4 of those a year as wear items. That doesn't bother me much since very little food gets in contact with them.

I expect my Snapware/Pyrex food storage sets to largely outlast my lifetime, but without lids to match once they stop manufacturing them.

The plastic lids always break way more quickly than the glass containers IME. Can't remember the last time I broke a glass one, actually. Plus, they actually stay in good condition. An abused plastic container will cloud, warp, gouge, and release god knows what into your food the whole time.

I tend to buy ones with glass lids by a french company named O'cuisine. The glassware has held up over the years and didn't cost very much

Also, "microwave safe" does not mean it's safe for people... it only means the container won't melt in the microwave. If you're going to reheat leftovers, definitely don't keep it inside a plastic container.

I also switched to glass containers and stainless steel everything, about 20 years ago, out of distrust for reasons like in this article.
