I was leafing through the How to Spend It magazine put out by the Financial
Times. In an article about store buyers, the woman who buys table ware for
a hoity-toity dept store in London and who has some sort of degree in
ceramics was showing off some dishes she's very pleased to sell. They are
white outside with a sea-blue crazed glaze on all the interiors and very
pretty too. She claims that the crazing can only be achieved if the ware is
fired to precisely the right temperature. Sounds like 'baffle them with
bullsh.t' to me but it drives the price right up by making crazing sound
difficult to achieve. Ha. I would bet those plates couldn't tolerate any
lemon wedges for long.

Interesting how it's OK to lie to sell something - still - and always will
be I suppose. I suppose the only way to stop the bastards is to sue em.

An interesting facet to this discussion - it is as easy to get a glaze to
stop crazing as it is to make it craze - if you know how to do one you know
how to do the other. Same with durable glazes - if you want em you use the
same technique as you would to make unstable glazes.
