        In the course of excavating a turn of the 18/19th century slave
quarter we have uncovered a concentration of material that has been
identified as possible bloomery slag.  The material in question is grey,
burnt and slightly porous and in one case has partially vitrified; it is
rounded and bulbous in form.  We would be grateful for any information
that you could pass on about bloomery slag (and bloomeries in general),
especially images.  If you don't want to reply to the group as a whole then
please respond to [log in to unmask] or snail mail to the address below.
