Aluminum vs. Aluminium[edit]

Magnetic properties of aluminum[edit]

Aluminum is paramagnetic[1], not nonmagnetic. I think this should be fixed. 23:30, 21 March 2016 (EET) — Preceding unsigned comment added by Dexterelu (talkcontribs)

Aluminium in ship building[edit]

It looks like some of the sources deny the fires as a cause of the discontinuty in the use of aluminium in naval ships.

" Health concerns" section[edit]

I was visiting East Germany close before and after the unification. What surprized me most was the complete, I mean really 100% complete disappearance of aluminium cookware from shops. This means that health concerns with aluminium was pretty high.

Therefore I noticed that the article is somewhat self-contradictory: "The use of aluminium cookware has not been shown to lead to aluminium toxicity in general..." and right next to it: "Studies have shown that consumption of acidic foods or liquids with aluminium significantly increases aluminium absorption". "significantly increases" - does this mean to dangerous levels?

Second, was there any legislation against aluminum cookware?

In general, it will be interesting to have a historical overview of attitudes towards aluminium pottery and tableware. Staszek Lem (talk) 16:16, 26 April 2016 (UTC)

Well, I'm no expert, but I'd imagine that the first sentence you quote answers the question about the second: while acidic foods may increase one's aluminum absorption, it has not been shown to be at dangerous levels that would lead to aluminum toxicity. The two aren't contradictory. I also wouldn't personally speculate on aluminum cookware in East Germany, but health concerns aren't the only reason one might not see aluminum in shops.

I am not asking you to speculate. I had a prominent observation: I was specifically asked to buy a particular kind of aluminium cezve I brought from the previous trip; I've had a business trip across a dozen of East Germany cities and was surprised to see only brass and stainless steel ones, and that's why I noticed that the rest of aluminium cookware disappeared as well. Here is my question: why? Certainly it was a prominent reason, deserved to be described in wikipedia (unless my memories fail me). Staszek Lem (talk) 18:48, 26 April 2016 (UTC)
P.S. I did google a bit and did see claims about Al pots banned in Europe, but some other sites claim it is bunk. So even this claim is a myth, it is quite common and may deserve some research as well. Some of good mythbusters are [1] and [2]. Still, what I saw is my anecdote, of course, but I don't think my brain fails me (yet :-); I don't use Al cookware, neither I am wearing Al tin hat  :-). Staszek Lem (talk) 18:54, 26 April 2016 (UTC)
[3] "Various factions in the German government, says Mittelman, have tried periodically to ban aluminum cookware by law". Staszek Lem (talk) 19:06, 26 April 2016 (UTC)
I don't have hard data either, but I notice that pressure cookers are still mostly made of aluminium, which one would expect to dissolve faster than normal cookware. Most other types of aluminium cookware available in UK are lined with non-stick coatings. If there are health concerns they are likely connected with Alzheimer's disease see (Cause#Other hypotheses) and early onset dementia. Use of al foil remains almost universal. Plantsurfer 19:12, 26 April 2016 (UTC)
AFAIU pressure cookers (and aircraft) are made of al-based alloys, which may (or may not) bind Al much stronger against dissolving/reacting. Staszek Lem (talk) 19:27, 26 April 2016 (UTC)
From some texts and from personal experience, when aluminium pots are used to cook or store acidic foods, it oxidizes heavily (yes, I am aware that Al is always covered with a thin but strong film of oxide) and with this it deteriorates the taste and color of food. Staszek Lem (talk) 19:27, 26 April 2016 (UTC)
That discoloration, and the fact that the pans slowly dissolve in a dishwasher, probably has a lot to do with the modern preference for stainless steel. I doubt if aluminium toxicity is a major concern for consumers in this country. Plantsurfer 19:41, 26 April 2016 (UTC)
