i have two canteen setups , one has a plastic canteen and an alloy cup housed in a cover to go on my belt , the others a stainless canteen , with an alloy cup , and I've got the stove stand for it, housed in a cover to go on my belt. My question is can I safely boil water in the alloy canteen cups ? These both fit on a belt so they don't take up pack space. I'm thinking once the water cools in the alloy kidney cup , I can fill the canteen . I've got puro tabs and a life straw , but I really just wanna know if you can boil water in an alloy kidney cup

If by "alloy" you mean hardened deep drawn aluminum, they are fine to cook/boil water in and drink/eat from.
 
I'm not sure :( it just says alloy , they have the DoD arrow and number though , and they seem like aluminium , but heavy gauge aluminium , if that makes sense.

I've wondered about aluminum due to concerns about metal leeching into the water/food/etc. Is that actually a concern? How do you know if it's "hardened deep drawn aluminum"? Is steel/titanium a better choice?

Let's see. First, if you want to know the actual metal used in the alloy, the Defense Department specs are out there to find. Aluminum is the most common I have found though likely some stainless alloys also exist. As to leaching, meh. Are you going to eat and drink out of it 24/7 365 days a year for the rest of your life? No? Then there is no problem. High acid foods and liquids will dissolve more metal particles than neutral or slightly alkali/acid will. But still not a concern. As a kid we had colorful anodized aluminum tumblers that we drank koolade from and they gave the drink a tangy flavor as they were etched. But no harm ever came from it that I am aware of.
 
just use 'em. you are probably going to get more aluminum in your daily life from your food than you will from your canteen cups. If aluminum is a worry to you, then don't use anti-persprant, its got a far greater level of absorption.

Steel might leech nickle, which some people are allergic to, and titanium isn't fully stable either. Add to the fact that who knows what is all in modern metals that are smelted in china. There might be other impurities (like the time they smelted half a decommissioned nuclear reactor for bridge steel) Worrying about it is probably more a health risk that enjoying your time outdoors.

I have to agree.

I use to this day, my grandparent's cast iron. The nested pans [including a Dutch Oven] were passed down to my parents and then to me.

One would argue that using 80+ year old cooking implements is as dirty as cooking on the actual ground. Since there was nothing wrong with the seasoning, I've never stripped or 'refinished' them. Yet, none of us ever got "sick" from using them.

One in my situation might strip off the old seasoning and create new...which is purely their prerogative. IMO, it's unnecessary because they were fully functional right from my parents.

Now if I bought pans at a yard sale or something, sure....I'd strip them down to the metal and redo them. I'd do it even if the seasoned finish was 'perfect'.....one never knows what was made by a previous [non-family] owner. That's just common sense though.
 
DoD arrow = Dead On Drinking, and the arrow points to you....(joke)

Aluminum is fine for cooking, do not worry
 
Not sure about using purification tabs in aluminium cup/bottle, but boiling water/cooking in it is fine, there's been plenty of pots & pans made out of aluminium in use for many years.
