A Late 13th and Early 14th-Century Tile Factory at Danbury,Essex

THE EXCAVATION of a practically complete medieval tile factory, in operation between c. 1275/85 and 1325/35, is described. The establishment comprised three buildings, interpreted as workmen's accommodation (A), a workshop (B), and a drying shed (C), together with two kilns, within a ditched roadside enclosure. The kilns were of the normal type, with two parallel flues; one had a walled stokepit reached by a tile staircase. The methods of tile manufacture and firing are discussed, the conclusions being partially supported by experimental evidence. The patterns of the decorated tiles are seen as derivatives of the Chertsey-Westminster School, mostly via the 13th-century ‘Central Essex Group’; a relationship with Penn is also suggested. Distribution of Danbury products is largely confined to the Chelmer valley, but a waterborne distribution is suggested by a group of floor tiles from Virginia Water, Surrey.
