I suppose that what gives me pause is the notion that the colored glassy
compound is FUSED to the surface:  this is surely not the case in any of the
tin whatevered wares I have seen, used, dug up, studied, or otherwise had
any acquaintance with.  But I was told by a ceramics expert (cannot remember
which one) that while Barber and others had used the term enamel it was not
strictly accurate and like Carl says we should move on when we know better.


I've been  preparing for the artifacts class I'm teaching in the fall so
have found this exchange  enlightening & I wish I could afford that book
that G. Avery edited.  Sounds like it would be most helpful.
