[Ansteorra] a question for any potters...

[Maleah]

One quick note here. Generally the term "greenware" is used for the clay 
before its first firing after it has been taken from the molds or off the 
potters wheel. The term used after the first firing and what most people who 
work with ceramics call unglazed pottery is "bisque" or "bisquet". Most of 
the items I've seen, even from period displays at the Victoria and Albert 
Museum, where the outside is unglazed the inside is glazed or paraffin 
lined. Unglazed will tend to wick a certain amount of moisture from the 
atmosphere. Not sure if it will be enough to effect your salt (remember that 
salt draws moisture as well, that whole osmosis thing). Hope these ramblings 
have been helpful.
