Title |
An incomplete Roman ceramic Lowther's Group 5 and Betts Die 79, relief-patterned flue-tile dating from AD 150-200. |
||
Description |
English: A fragment of a Roman ceramic Lowther's Group 5 and Betts Die 79, relief-patterned flue-tile dating from AD 150-250. A similar tile is illustrated in Betts et al (1997:56 Fig.27d No.79). The front is decorated with relief-patterned rolled design in the "Diamond and lattice" group style. Betts writes "Keyed with wooden rollers applied when the clay was still damp, before they were put into the kiln to fire. This was added so the tiles could be more firmly mortared into place." The fabric is fully oxidised and red throughout. Betts et al (1997:131) write "There is no useful dating evidence for die 79."
McComish (2015:12) writes "Box flues (tubuli) are hollow rectangular or square cross-sectioned tiles, with sanded interior surfaces, and they have vents in two opposing sides, while the other two sides are usually keyed. The keying can be incised, finger drawn, combed, or relief-patterned. There is no standard size for box flue tiles nationally (ibid., 74). Box flues were made by wrapping a slab of clay around a sanded former then joining the edges of the clay together with a single seam, and the vents were cut out after the tile was removed from the former (Rudling et al. 1986, 204)." Dimensions: length: 68.10mm; width: 51.03mm; thickness: 11.39mm; weight: 25.78g. Betts et al (1997:42) write "Some of the patterns are very similar in design. It is possible that they were made by the same die-maker, particularly if they frequently occur together on the same sites. This would suggest that they are contemporary, or nearly so. Dies showing marked similarities in pattern are listed below... Dies 79, 82.... Diamond and lattice dies 79 and 82 are known only from London."
