That's the longest list of "uses" I've seen for quite some time. This
stuff is, apparently, Really Useful.

Funnily the only use I knew is not in the list. Making ceramics
waterproof if you don't fire it high enough to be non-porous. E.g. if
you fire it Raku style.

I'm guessing that's similar to the concrete and masonry treatment they
talk about. If it makes concrete less porous, chances are it'll work for
other things as well...
(I wonder if it works for wood?)

Yes, it even makes pots that have cracks waterproof again.

AFAIK wood is generally not porous.

Yes it is. Wood's entire structure is composed of long tubes designed to
channel water (from the roots to the leaves). This makes wood quite
water-absorbant.

Which is why boats are built with wood exposed along the grain.
I've used water glass to keep eggs when refrigeration isn't
available, after about a month they start tasting odd though.

The convenient thing is that when they start to go bad, you know very
quickly. Good eggs don't float; bad ones do.

My cookery teacher told me this. Is it actually true?

Hmm, are you deliberately confusing water glass with a glass of water?

Yes. Have tried it and it works just fine.
Any reason why you'd think it doesn't work? ;-)
