>I am researching Roman lead (and silver) mining and processing in Wales (
AD 40 - 400)
Steve,
One source you may not have seen, and not strictly Welsh in the modern
sense, is Bayley, J. and Eckstein, K., Metalworking debris from Pentrehyling
Fort, Brompton, Shropshire, Ancient Monuments Laboratory Report 13/98 (1998).
Although the source of the metal was probably the western mines of the
Shropshire field, it does provide an example of the industrial scale of
silver recovery from lead deposits in the Roman occupation period. The size
of the cupels, at c. 0.5 metre diameter is comparible with the size
calculated for the refining hearths used in the Devon silver mines of the
late medieval period.
As to a list of Roman lead pigs - I use that in Tylecote, R. F. The
Prehistory of Metallurgy in the British Isles, (1986), pp. 61-71, tables 38
and 39, but I doubt if it is a definitive list these days.
