On the other hand, the case of the pair poisoned by the pewter mug over
ten
years, sounds reasonably possible, given that they were drinking some kind
of ( unspecified ) fizzy reactive beverage from it, which if fruit based,
may well have been quite acidic.


I dig out my handy Exstik II PH meter and measu
Tap water : 6.7
Western Family Diet Lemon Lime: 4.1
Western Family Lemon Lime : 3.3
Coca Cola : 2.6
Ocean Spray Cramberry Cocktail: 3.5
Lemon Juice (added to tea) : 3.0

Oh, here's a PH table from the UK:

Soda pop and fruit juices are sufficiently acidic to leach out the
lead in pipes and drinking cups.

OK, thanks for that. Looking at some of those figures, no wonder these
drinks rot your teeth away! It's like drinking schoolboy chem lab bench
acids. I seem to recall that some of them weren't much lower ...

Still, that certainly confirms what I thought about the pewter mug case. We
still don't know what the actual effects of this long term exposure was to
these people, or exactly how much they ingested. I don't suppose that you
have a bottle of beer to test the ph of, do you? It used to be very common
over here for regulars in village pubs, to keep their own ( often pewter )
pint mug behinf the bar. In fact giving one of these as an 18th birthday
gift ( legal drinking age here ) was at one time quite a tradition. My next
door neighbour certainly used to take one with him every night to the local
pub, but I don't know if he still does. I'll have to ask him.
