A single, complete box flue-tile (300 x 360 mm). This would have been joined to others in order to provide a pipe to carry hot air up the walls. Patterned with a comb, which created wavy lines. This was in order that plaster would adhere to the tile.
From the hypocaust of the large Roman villa at Eastbourne. For many years, this tile had been lying in the rockery of an 18th century house called 'The Greys', along with other material from the villa.
