Terry:

An interesting question would be if the lead leaches into the
alcohol
over time, could one leach enough out by storing successive
amounts
of, say, cheap methyl alcohol in it over time and disposing of
them until
the amount that could work into stored potable spirits was
negligble?

The alcohol is not the factor. It is the slightly acid aspect of wine.
The original concern of the actual tests
was whether lead crystal drinking glasses leached enough lead to make
drinking from them risky. The result
of the test was to conclude that there was no risk and all that needed to be
avoided was long term storage.
Potable spirits probably (although this is not tested) do not absorb enough
to think about.

Allan, while I'm a newbie to this group only because I finally kicked my son
off the computer long enough to set all my stuff back up, I'm NOT new to
lurking over Mike Firth's shoulders to bask in the glow of his knowledge.
You can't go wrong with anything he has to say about glassblowing. You have
no idea what I've learned from him through his website, and through the Wet
Canvas forum. I've learned as much lurking as I would have in any
glassblowing class. Trial and error will teach you much, as well as every
little burn and blister. Good luck!

Thanks, Debbie. So far, I've found Mike Firth's comments to be very helpful.
In the last week or so, I came here with specific questions that I felt I
needed answers to for my own purposes, conceived in isolation and without
reference to other points of view. For the most part, I've been received
very cordially by readers of rec.crafts.glass and I am very grateful for
the help I've received here. Now that my original questions have been
answered, I plan to follow your example and lurk in this group and see
what else I can learn here from discussions of questions it has not occurred
to me to ask.

As was said, it's not the alcohol itself that is the problem. Leaching
of the lead from the glass surface will leave a silica-rich network,
which will probably show up as a semi-opaque layer on the inside
eventually. This will be porous and the lead may well continue to
leach out ad infinitum.

A better method, were it practicable, would be to coat the inside of
the decanter with a resistant layer.
