2007 was a good year for my ceramic building materials publications to appear, and this one can be found in the Yorkshire Archaeological Journal for 2007, Volume 79. The CBM report is co-authored with Cecil Spall, and can be found on pages 293-297. Of main interest was nib tiles, which seem to be a very typical product of South Yorkshire.
Congratulations to Chris Fenton-Thomas in getting the whole excavation report in print so quickly. The full reference for the whole article is:
