Ivor --

What you say about Kingery is very likely so, but
what you fail to mention is that Kingery is an
engineering textbook requiring a solid engineering
or science background to follow, and is only occasionally
relevant to a potter's needs.

Lawrence is generally relevant for a potter, the science
is not so detailed or so daunting, but appears to be
applicable, and it is apprehensible without references to
Schrodinger's electron model and other high-faluting hoo-ha.
In the few cases where I've looked something up in both
Kingery and Lawrence, the two have been generally consistent,
but Lawrence has been substantially briefer.

Cardew's is an especially notable work because it doesn't
require any particular technical background, and is
entirely relevant to a potter's needs. There are no
dents in the wall of my study that match Cardew's
book, there are several that match Kingery ... the dents
would be deeper, but the book is so frigging heavy that I
can't get good velocity with it ...

Yours -- Steve Slatin
