I have just bought a clay baker on sale.  I don't know much about them as I usually bake my bread

in non-stick metal pans, but thought I might experiment.  However, after reading up on TFL about them

it appears they should be unglazed.  The one I bought is terracotta and made in Portugal (I have great faith

in European products).  However, after getting it home I found that the inside is glazed (but not the lid).

It also states it should never be soaked.  Is this O.K. for baking bread or should I return it?
