Re: Help with what I believe is a hardening issue

        That is not a bad idea but the 'hazardous material' shipping would be
costly. I rermember purchasing some AgNO3 (like 6 pounds) a few years
ago at a great price. Then, about a month later, after I'd sold it all
@ cost to my students, the hazardous material shipping costs for $190
came in.

This also is more or less my experience, though only from the '80s, not
the '60s... However, Jack, permit me to suggest that you sell the
remains of that gallon in, say, 8-ounce containers for, say, $40
each.... you could make enough to buy that Christmas laptop -- Oh, wait
a minute, that was Tom. Well, at least a good dinner out.
