OK, google for 'chest of draws' and you'll be amazed at the number of

Just because someone avers that builder's lime is slaked lime doesn't
make it so, but it gets on Google all the same.

No, an elementary knowledge of chemistry, aided by a few hundred

Biulders' Lime really is Calcium Hydroxide, known as "slaked

It is an alkaline material which is very frequently used to treat
acid soil.

We'll have to agree to differ, my searches and the GQT team back me
up but who cares really lol. All the best

But every gardener _should_ care; and it isn't a "lol" matter. What
searches? What exactly did which members of the GQT team say about
it?

I've just done a very swift (admittedly _very_ swift) Internet
search, and the nearest thing I found to your position is a site
which specifically recommends that builders' lime should not be used
in desilting operations because it may contain impurities which could
upset the chemical balance of the environment to be treated. A quite
separate issue from the material's garden value.

Just as I believed, there are, or perhaps have been, perceived to be
roughly two grades of hydrated lime, and in trade they are, or
perhaps have been, sometimes distinguished as "slaked lime" and
"hydrated lime"; but this is a convenient traditional distinction,
not a scientific one. I'm still quite sure that "builders' lime" is
not quicklime, which is a bugger to store safely; I find that Build
Centre don't appear even to stock it, though they do stock two brands
of hydrated. (I'm sure they could get it for you, of course.)

This "Who cares really?" is a suicidally bad habit the British need
to grow out of. For some reason a country which _excels_ in academic
and scientific research and music -- all disciplines in which
precision is of the very essence -- also has a culture which derides
precision (note the use of such insults as "anorak" and "pedant" from
top to bottom of the society). Perhaps it's a healthy balance, but I
don't think so: more a "them and us".

I'm sorry to go on and on like this, but I've got the bit between my
teeth!

It was used in plague pits.

Not very recently, I would venture to suggest. In 'official circles' the
myth that it had a caustic action on bodies lasted well into the last
century.

Not "someone". I stopped after I counted 20. They occurred in about
the first 200 entries I looked at. Linear extrapolation says that in
110,000 hits there might be an expectation number of about 10,000 folk
who say that builders' lime is calcium hydroxide

Yes but this is unlikely to be replaced soon, if you ask a plasterer to save
any sand/lime chippings you will soon have a few CWT for the garden...it
melts if left in water for long enough...the odd bit of gypsum won't do the
garden any harm if it's mixed in with the older stuff.

Yikes - that's *very* alkaline!

Though I admit, growing brassicas in chalky soil does mean I've never
had the pleasure of having to lime in the first place...

I wonder, though, if the plague pit theory wasn't in fact quite a

moisture and to some extent with exposed parts of the bodies might
have provided a sort of cordon sanitaire.

Ahem! Builder's lime is calcium oxide and is far *TOO* active on the

I can't remember the last time I saw Calcium oxide (quicklime) in
builders' merchants. What they invariably sell is hydrated or slaked
lime which is fine in the garden.

my gardening book has a section on the importance of liming, releases

but local garden shops don't stock it, and the one that does isn't getting
any more once it's gone. He eyes my grey beard and says it's only used by
old people and nobody else bothers

Not much to add to what's already been said except do base your use of
lime on evidence from pH tests and don't overdo it - especially
hydrated lime, an excess of Calcium can cause problems like rendering
some minor nutrients unavailable. This is a particular problem with
brassicas like caulis. Dolomite (Magnesian) limestone which is a
variable mix of Calcium and Magnesium carbonates etc is useful where
you want to get the pH up without overdoing the Calcium.

Wasn't there some association with the use of lime and an infamous murderer
- Crippen, perhaps? Years ago, I remember reading a Dornford Yates novel in
which a murderer used slaked lime instead of quicklime and thus preserved
the body he had hoped to destroy, which was buried in a pit in a barn, IIRC.
I think. ;-)
