BKW 99 - ISLE OF DOGS, LONDON

 

Ceramic Building Materials

 

by S Garside-Neville

 

Introduction

Two boxes of ceramic building material were submitted for examination.  The material ranges from medieval to post medieval in date, and comprises roof tile, wall tiles, floor tile, brick and a fragment of stove tile.

 

Medieval Material

The most common form of roofing material for London in the medieval period was two-holed peg (or plain) tiles.  There is one fragment of plain roofing material from 6/006 that may well be medieval in date.  However, the bulk of the sample of plain roofing tile may be post medieval in date.

 

Post medieval material

A sample of bricks was examined.  Some of the bricks have quite typical features associated with bricks of the 16th and early 17th century, eg. measurements and bright red colour.  Others have a more uncertain set of measurements and fabrics.  Using Lloyd's (1925) measurements for comparison and the measurements set by various statutes and acts, it has been possible to give some indication of the date of the remaining sample.

 

One brick, from 5/002, is obviously from the 20th century, and may be a paver.  It has a brick stamp which seems to show the initials BBC, and kiln number (5).  It is possible that this stamp is of the Butterley Brick Company, but further research would be needed to confirm this.

 

There is a fragment of green glazed stove tile from 2/001.  It is part of the coat of arms of James I, and shows a unicorn sinister.  It dates to between 1603 and 1625.  This tile fits exactly into matrix III as described and illustrated by Gaimster (1988, 319 and fig 5).  It is Gaimster's form b, which has a regular frame-like flange in red earthenware, and the moulded panel of the arms is in a white-firing clay.     The back shows cloth impressions.   It is likely that matrix III types are products of the Hampshire-Surrey borders pottery industry, which are termed as Tudor Green Ware (Gaimster 1988, 320).    Other well provenanced examples of matrix III are known from Cove (Hants), and the site of Wimbledon Manor (Gaimster 1988, 331-2).  Traces of mortar along a broken edge points to reuse.  The tile was found in Trench 2 which is thought to include the foundations for 'The Mansion House', so may well be associated with the fittings of the house.

 

There is one fragment of plain, unglazed floor tile of the type which can be associated with the post medieval period.

 

Pan tile is present, and can occur as early as the 17th century, though is used into the 20th century.

 

Modern material is represented by two tiles, one of white glass which may have come from a bathroom or kitchen.  The other blue glazed, dust pressed tile may have come from a fire surround.

 

Conclusion

There is a range of 17th century material, with bricks, stove tile and floor tile, and probable peg tile, included in the building programme on the site. Other works are hinted at by bricks of different measurements.  There is the hint of some medieval activity in the area.

 

The sample should be retained for further study.  In particular, the fabrics of the bricks and roof tiles should be tied into the collection of the Museum of London.  This will help pinpoint the date of the brick and tile from the site.
