The danger of acidic foods in copper pans is real. Leaving food in unlined copper pans and eating it the following day has killed people.
I bought DD a maslin pan on Ebay a few years ago it was very reasonably priced.
We were on holiday there at the time, whitewave [St Teath] and the friend we went on holiday with laughed at me because I bought bottled water that week for us to drink, but I'm glad I did. Some people were very ill. Not sure how soon after the event we were told of it; I thought it was pretty quick?
That was the worst water quality emergency in the UK. A tanker driver poured a load of aluminium sulphate straight into the treated water outlet. If people drank this water they would have ingested a very large amount of aluminium. It will have acidified the water and removed other metallic elements from pipes. Not the kind of trace amounts that might come from a pan.But no-one who has ever had anything to do with the water industry will ever forget it. Security at wt plants improved hugely after this event so that such an error could not be repeated. If I remember correctly there was a switch to an iron based chemical as well. The water company did not adequately warn people - by the time people became aware the problem will have dispersed.
The long term health effects are still being debated. See the wiki entry.
Does anyone remember the Camelford water thing where the water company put too much aluminium into the water? Well I was visiting relatives at the time in Delabole a village about 3 miles away, and have always been a big water drinker. Now I am not sure if it was remotely related but I came out in a huge hot rash for about a week or so after. I will let you know if I start forgetting things!!
'These days we are treating the biochemistry rather than the patient!" Yes jeni that may be true, but survival rates are still improving aren't they?
We may not like the biochem approach, but the stats show ....... it works!
I once worked with a registrar. He was very sceptical about all the biochemical tests we performed on patients!
He said 'we'll be wanting the serum platinum level next!'
I agree. These days we are treating the biochemistry rather than the patient!

YESS, WE HAVE NO BANANAS, WE HAVE NO BANANAS TODAAAYYY!!!! 
Salt!!!! We are on to sodium now? Not good for our BP.
I think fillings are have mercury in them and that has been another health scare put about on the internet for years now, without any foundation that I know of.
Any advance on mercury - working our way through the periodic table what with this thread and the one on bananas.
What was that about metal fillings in teeth? Weren't they suspected of causing dementia or something like that?
: I never use aluminium foil with acidic things.."
That is very interesting Jess. Never knew that.
The only thing I do know is that the habit of adding salt once the water was boiling arose to stop aluminium pans from pitting.
It is perfectly o.k to add salt at the beginning now a days.
...Not when you use aluminium pans...........
Perhaps non stick pans we use are also questionable?
What does the heat release, once that artificial coating is boiling hot?
I haven't done much jam or marmalade making lately but I have a large stainless steel stock pot from M&S that is quite big enough for my needs.
Aluminium is a more chemically reactive metal than steel. It will react more with acids in other words. And jam is acidic. But causes of dementia are still not known and no reason I think to worry on that score.
But ingesting large quantities of metallic elements is questionable - iron is I good for us, essential even in small amounts, but too much iron is not.
I never use aluminium foil with acidic things like lemons for that reason.
I've used a pressure cooker for ages to make jam (stainless steel). I lost my jam pan along time ago and didn't think I'd need it again so didn't bother replacing it. I decided to make marmalade last February and needed a larger size of pan so eventually bit the bullet and bought a stainless steel one on the internet.
This is the place I bought it from and I've just noticed they have a sale
http://www.preserveshop.co.uk/jam-making-equipment/maslin-pans?gclid=CNee7qnxhbMCFe_MtAodDVgAJg.
The aluminium one is £29.95 as opposed to £35.95 for stainless steel.
My gran always said to never use acid in aluminium pans - it certainly makes the side very clean.
Happy Jam making
Charity shops sometimes have jam pans, donated when someone who never makes jam is disposing of the kitchen ware of someone who did.
I think the link between aluminium saucepans and Alzheimers has been fully disproved. I bought a copper jam pan in a supermarket in France about five years ago. It is beautiful and light - but I cannot use it for chutneys because of the chemical reaction betwen the copper and the vinegar.
Ikea have some mega-sized pans at a good price. They may be suitable but I have not tried them for jam. They are very good for large scale catering though
I use a non stick pan from Asda -very large and not too dear-about one third of the price of those in cook shops. That was a couple of years ago-and I also use it for large quantities of soup.
Nothing to do with jam, but I was only thinking of aluminium pans yesterday. I stopped using them when my dad had alzheimers. This was a long time ago, but I wondered if there was actually a link. My saucepans are steel with brass bottoms; my son doesn't like using them because he says everything takes ages to warm up. But, as someone who's rubbish in the kitchen I don't make jam so can't advise on that one, I'm afraid.
I notice that most cookshops don't sell aluminium pans any more. I know there have been (I think unproven) links to Altzheimer's.
Am looking to buy a jam pan, and on a limited budget. There are aluminium jam pans available, they're light and cheap. They don't have to be very hardwearing, I'll only use it two or three times a year max.
I'd like one with bigger diameter than 13", but there seems to be a very limited choice there.
Easy to clean is good; but I've not yet seen a non-stick one. Why not?
Steel ones are heavier and dearer. Brass ones (better conductivity, and jam does burn easily when I'm making it!) seem to be a thing of the past.
What to buy? And where, for a good price. Online seems a likely answer, but these items are understandably expensive for p&p. Yr advice please.
