English: A body sherd fragment from a Roman Trier black-slipped ware (Moselkeramik) folded beaker dating to AD 180 - 250. The sherd is folded with four evenly spaced rouletted bands. Both the inside and outside are coated in a dark glossy slip. The interior surface is undecorated but has regular striations from the wheel turning process. The fragment has a hard-red fabric with no visible inclusions, it has fine grey layers underneath the colour-coating of the inside and outside of the vessel, giving a 'sandwich-effect'. Symonds (1992:49) writes "This relatively complicated sandwich-effect is unique to Trier vessels, and it suggests that possibly they were subjected to a more complicated firing process than other vessels... The dark colour-coating is generally very glossy, in some instances achieving a truly remarkable depth and quality." A similar rouletted folded beaker can be seen in Richardson (1986:120 Fig 1.130), and a full range of Trier black slipped folded beakers can be seen in Symonds (1992: Fig 26: Group 33 - Fig 27: Group 35).

Dimensions: length: 59.95mm; width: 52.93mm; thickness: 2.41mm; weight: 13.16g.

Symonds (1992:51) writes "...each separate Group tends to have a specific set of characteristics which are almost always present. The folded beakers of Group 35 (figure 27), for example, tend to be rather taller and narrower than vessels of equivalent size in other groups."

Symonds (1992:46) writes "Trier beakers must have been made singly, and decorated free-hand... the skill of the Trier potters in achieving a deep, brilliant gloss was better than any since the production of Campanian wares.... Dark colour-coated wares were probably first produced by the middle of the 2nd century, but did not achieve wider distribution until the end of the century... Trier beakers recently found at New Fresh Wharf in London (Richardson 1986) is dated to c.220... the end of sigillata production at Trier, and also that of properly 'fine' wares, was also apparently influenced by a major political event, the invasion of barbarians across the Rhine in the year 276."
