I've been out of town for four days, and I came home to hundreds of clayart
posts, mostly about haggis, and I find an e-mail from a non-potter friend
with a long list of Jewish foods with a cross reference to haggis! (WG)
Must be something in the air?

But on the lead crystal leaching thread - there was an article in (as I
recall) Science News several years ago about leaching of lead from lead
crystal. A group of scientists was addressing lead issues, and they
speculated over lunch that lead crystal might leach. They came back to work
the next day with every lead crystal decanter that they could obtain at
home and from friends and family, and tested the alcoholic contents for
lead, and sure enough, every sample was full of lead - the older the
contents, and the stronger the alcohol, the greater the lead amount.

Their conclusion was that you should only use these decanters for serving
the alcohol, and not for storage. Their tests showed that there was almost
no leaching of lead over an hour or two, but over time, it became quite
dangerous. So, I would presume that drinking wine out of a lead crystal
glass would be quite safe, as long as you did not sip the contents over a
week's time.

This was "big news" at the time - made it onto TV news, even, but seems to
have been forgotten.

"They" recently exhumed Beethoven and removed
some hair or finger nails or something... Seems
the poor man suffered from extremely high levels
of lead. That poisoning could well have been
the cause of his psychological state, not the
deafness.

"As mad as a hatter" refers to the occupational
illness which afflicted people who worked in
that profession... They inhaled the nasties
whilst steaming the hats...

Regensburg, Germany: Many of the old houses are
apparently so badly polluted by the lead and
mercury which was used to make mirrors for
centuries, they should really all be pulled down
and designated as toxic waste.

And of course the Romans had lead pipes... Must
have been the reason for an orderly, civilised
and extended military power being wiped out so
easily by a few nomads...

So watch out!

There is, however, no lead in Haggis. Honestly
:-)

Are you sure Dear, it feels like it when I eat it, and lands in my
stomach like lead!
