Why does pottery become scarce during the Saxon/Anglian period...

[Marc Berger]

the occurrence of ceramics in post-Roman England was any greater or any less than late Iron Age societies elsewhere in northern Europe

thing is that "late iron age" terminology in britain and any of the roman provinces is pre roman and to a certain extent saying " late iron age of northern Europe" also suggest that that culture replaced a vaccum left by the romans when applied in roman britain areas.
Whats dinos might be getting at is that the vacuum might not be along the roads and I am seeing that as a filter that had started before the romans left.

For prentice there is late roman in the 5th [SIZE=3]http://www.ncl.ac.uk/historical/assets/documents/Roman%20Pottery%20Conference%20Programme.pdf[/SIZE] where do they do without pot for hundreds of years

and also what i think could be important for my area is cultures like the terps or torps or thorps of the frieziens which if anything are abandonded and open to a sense of the "migration" period by the 5th and the great formation of old english. Still trying to get round to getting details out of records such as these [SIZE=3]http://www.jalc.nl/cgi/t/text/text-idxae2c.html?c=jalc;sid=095741f1231d8f86c4f63866855fbf08;idno=m0402a03;view=text;rgn=div1;cc=jalc;node=m0402a03%3A4[/SIZE]
