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.

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.
