I would have assumed (probably incorrectly) that the 'seal' which would come in contact with the glass & liquids would be a type of silicone lid, while it could be considered a type of plastic, if its a good food grade lid, I would imagine it's a bit better ? Ironically though silicone is much harder to recycle though.

U don’t recycle plastic, you burn it in a furnace. Spread the word.

Not sure if you're serious or not, but plastic should not actually be put in the recycling bin. It almost never gets recycled, and if it does, it degrades quickly and becomes more toxic after recycling.

Plastic is garbage. If you live in a place that burns garbage for energy, that's the best fate for it.

If you can, there are some great borosilicate glass containers out there. I use them for everything. The ones I have seal well enough that I can fill it with soup and stick it in a backpack, ride somewhere and it's fine on the other side. Thick enough to be basically unbreakable, microwavable, dishwasher-safe, etc. Don't need to worry about tomato staining either like on plastic. I've been thrilled with mine.

> basically unbreakable The clip-retaining rims seem to love to chip on the IKEA 365 style ones. The long-tabbed GlassLock ones seem less vulnerable to that. Which not unique to glass boxes, I'm still amazed by how robust the living hinges can be, some are going on 10 years and haven't split yet.

That's interesting. I have around 10-15 of those IKEA 365 glass containers with plastic lids and have never had them chip. I stick them in the dishwasher all the time.

We threw away all our glass containers because they constantly chip. I'm more afraid of ingesting piece of sharp glass than nanoplastics. I don't know why that keeps happenning, I guess dishwasher's high heat damages the glass or they keep bumping into each other.

You would poop the glass though

Yeah, generally speaking unless it's a very large shard and cuts your esophagus, once it reaches your stomach, acids will knock the edges off and it'll pass without issue.

It would be worth checking that the concentrations of microplastics used in this study are of a similar concentration to those found naturally. Otherwise the research is not very meaningful.

Could you elaborate on naturally found microplastics?

I meant microplastic concentrations in the real world, i.e. not in a lab.

If the concentrations of those used in a lab are far in excess of those in the real world, then these results may be of less concern.

My mum when I was a kid in the 90s: we don't store things in plastic, glass or ceramic only Me when I was a kid in the 90s: mum is a f'ing idiot wtf is wrong with plastic this hippy shit is dumb My mum 2020s: so plastic huh? Me 2020s: ugh.

It may be how you load, I don't think that's a common issue. Microscopic bits of glass are basically sand though so I wouldn't worry unless there's a lot or it's getting airborne.

Sorry people, but you can't stop it: 1. https://www.euronews.com/green/2022/04/11/how-much-plastic-d... 2. https://www.theguardian.com/environment/2022/mar/24/micropla... 3. https://www.theguardian.com/environment/2019/apr/15/winds-ca... Because humanity and capitalism's incentives are just wrong. Bottling companies like Coca Cola and Snapple have long switched to plastic bottles, and externalized the cost to the env…

One of my favorite quotes is: "A problem is a challenge with a least one workable solution. A dilemma is challenge with multiple choices, all equally bad." If we eliminated all PFAS chemicals today, society would collapse. What's the point of eliminating PFAS chemicals to improve life expectancy if the very act of doing so would cause a famine?

What products use PFAS whose absence would cause society to collapse? If you look at the major sources of PFAS by 3M, it's not like these were essential products. Here's a random list from wisconsin.gov:

Cleaning products. Water-resistant fabrics, such as rain jackets, umbrellas and tents. Grease-resistant paper. Nonstick cookware. Personal care products, like shampoo, dental floss, nail polish, and eye makeup. Stain-resistant coatings used on carpets, upholstery, and other fabrics.

In the paper they mention a concentration of 20ug/ml. I haven't compared this to what is typical for drinking water, food, etc.

From what I've read, if you filter out children under 5 in that statistic people lived into their early 60's pretty regularly.

High child mortality is still a bad thing.

Not saying it's not, but the implication that everyone was dying at 30 isn't true.

By "too young for glass", I'm assuming you mainly hint at weight – which happens to be basically the only, but quite significant downside to glass. The material itself is already about 1.5× to 2× as dense as your average container plastic, plus since you're aiming for at least a decent strength, on top of that the wall thickness will probably be several times larger too.

Plain glass jars can break if dropped (or thrown) off the table. If I'm sure a jar is borosilicate then I might consider letting my child drink from it, otherwise it's not worth the risk.

I've heard of a very small child being offered a sip from a thin glass and biting a chunk off the rim. Fortunately no harm was done.
