][<en,
Seems to me that anything that's water soluble (like f'rinstance, sugar, or
soap flakes) that gets a glaze over it is going to cause trouble when
moisture gets through the cracks in the glaze. Besides which it would form
caramel, or sorghum, or some such delicacy in the course of being fired and
probably do all sorts of nasty things to the ceramic glaze in the first
place. What makes you think there's a construction-confection connection
here?
Than again, what do I know about big-city problems, like tile or terra cotta?
I'm just some suburban geek who reads old newspapers and emails too much.
Boo hoo,
Ralph
