I was going to use it for meths for my Trangia? No problem with leaching for that is there?

Generally speaking, there won't be much if any leeching from cold water as aluminium is pretty unreactive. It's when you scrape aluminium (such as when cooking and with a harder utensil i.e steel spoon) that you get aluminium leeching into the food.

I initially agreed with you (about most likely a low rate of leeching in cold) but on second thought,
considering drinks can still taste gross from plastic and metal after relatively little time,
I do think that leeching still occurs too quickly. (Not sure about ice cold, but cool to moderately cold, I think
the gross taste still occurs....not that taste is the best indicator....probably way too many molecules leeched
by then....our tongue receptors are not that sensitive. :stuck_out_tongue: But I don't have a chemical analysis machine so.... :/)
On your heads be but I would not recommend it. Especially not aluminium. (Which I assume is worse than steel/iron.)
Sigh....I need some portable tea/coffee/hot chocolate container solution...
I may have to test glass with hot stuff....obviously I won't move glass from hot to cold rapidly.....that can cause a breakage/shattering.
If it fails.....I'll probably be desperate enough to use steel.
Those glass interior, metal thermos bottles break too easily.....(if its type of glass is even safe...I don't even know....)
but a silicon sleeve might fix that....
Only other consideration I have in this regard, is some safe indication if
the glass breaks without having to drink broken glass to find out. :confused:
Hopefully normal glass will save me... :wink:
Scientific tests ahoy!:man:

I personally would recommend avoiding metal containers, especially aluminium ones. (And especially for hot drinks.)
I know that aluminium is linked with a higher risk of Alzheimer's disease but I don't know
at what rate aluminium leeches from the bottle into the drink at cool/cold temperatures but I still wouldn't risk it.)
Steel or iron is probably better (although they leech iron, chromium and nickel) but the best option with probably no leeching of any kind,
is probably going to be glass (NON-lead/NON-crystal glass) or ceramic.....if there's such a thing as ceramic bottles.:confused:
I've got a glass water bottle that came with a silicon sleeve.
I quite like it but I haven't tested how well the silicon protects the glass from breaking
since I haven't dropped it. I'm also not 100% sure it's absent of lead but I doubt it has any....guess I'll have to research how you can tell if glass contains lead or not. (I'm going to guess the colour of the tint might reveal what it contains.)
And besides, metal bottles leave a nasty taste in your drink (from experience).
Plastic bottles have the same problem: leeching toxic garbage AND making your drink taste gross. (Especially after a few hours of leeching chemicals).
Hope that was informative. :smiley:

I prefer stainless steel, but this is perhaps better than plastic...
