Metal, glass or ceramics are all fine as long as you fill them yourself with tap water. Bottled water from the store often contains microplastics that got in there during the filling process so the container material isn't the only thing to consider.

Any bottles that are not plastic. So glass or metal.
What about Glass Bottles?
if you're worried about microplastics, consider a stainless steel bottle. Clean Canteen is a solid brand that doesn't put plastic films on the inside.
but I've only had a 'problem' with rather old bottles cracking (crazing, technically,) from age. Bottle Bright might be more harsh and prematurely aging your bottle if you consistently have a problem. I just use warm water and a scrubby somewhat regularly.
Any idea if ceramic linings contain epoxy or plastic?
Assuming you’re just using it for water or something and not actively cooking, a good bottle should be fine- the ceramic lining is basically sintered on at high heat and will improve the inertness of the pan.
Cheaper versions I’d stay away from (same as cheap aluminum or stainless bottles.)
Yeah was more referring to frank green water bottles
There was a recent post somewhere bringing attention to how ceramic pans are often not truly ceramic but an amalgamation that includes more questionable materials and/or being only a thin layer covering lower quality metal that could leach. That would make me wary of bottles with ceramic linings
Ceramic pans are usually sintered on at high temperature, but the coating is friable when it heats up.
Some is always coming off in the food.
I would suggest going to either carbon steel or cast iron pans. Cast iron might take some more care each wash, but it was the OG non stick and the seasoning is maintained with cooking fats… as you… cook.
There are some drawbacks that (tomatoes, for example.)
Is ceramic harmful if you ingest it like that? It's mostly just carbon and silicon, right? Like eating sand.
Depends on what it is. Silicon carbide is “just” carbon and silicon. There’s other kinds like zirconium which isn’t.
Also, the cheaper “ceramic” pans aren’t actually ceramic in the engineering sense. They’re more like ceramic powder held in some kinda binder and that binder is probably very not good for you.
The fact that companies like green pan won’t say what their “ceramic” actually is says a lot about the matter.
I would suggest going to either carbon steel or cast iron pans.
Particularly since the article that poster was referring to (I think this was the one) points out that the coatings were actually proprietary formulations and the manufacturers would not reveal what chemicals went into the manufacturing. Thus, no one has any clue what is really coming off in your food nor how toxic it might be.
Yeah I've not personally used anything but steel and cast iron for years now
A while back my grandma found out I love cast iron. she basically handed me all of her grandma's cast iron.
good luck getting any modern nonstick to last that long.
I have a stainless steel bottle, 40oz. I have never seen what you are asking.
Uhh what? I have never encountered a water bottle getting chipped or leaving shavings. Are you literally making your own bottle?
I've seen chipping on two black plastic Hydro Flask wide mouth lids, and it looks unsafe.
The last time I drank out of a reusable bottle, I felt a string-like thing on my tongue, and when I grabbed it out, it was black, and way too thick to be hair. I don't know for sure where it came from, and I'm only 80% sure it's a problem with the bottle or lid.
The metal version of the Hydro Flask wide mouth lid has a 1-star review about "yummy metal shavings".
Sounds like Hydro Flask might have some QA issues. Perhaps seek metal and an alternative brand with good ratings.
Been using them for 15 years; the bottles get a few dents in them, but I’ve even been able to hammer most of those out.
Haven’t used a plastic water bottle since the early 90s.
My camelback stainless steel water bottle has none of these issues. You shouldn’t drink out of plastic if you can help it anyway.
