Okay, I think I know the answer to this but somebody please set me 
straight if I'm wrong ...

I've been looking at mid-late nineteenth jiggered and/or molded 
bowls, where the exterior rim is salt-glazed and both the interior 
and exterior (below the rim) are Albany slip-glazed.  Since none of 
the Albany slipped surfaces show any salt-glazed effects 
(orange-peel), it would appear that none of the salt in the kiln is 
reaching the Albany surfaces.  Therefore, I assume that "stacking" of 
the pottery is effectively impeding the interaction of the salt 
vapors with the Albany slipped area.

Now ... I think I can visualize the stacking arrangement ... but it 
seems inevitable that the vessel at the top or the bottom of the 
stack would be at least somewhat affected by the salt ...  But I have 
yet to see any evidence of that.

Would appreciate any clarifications or comments that would alleviate 
this stressful line of thought.
