Comments specific to this amphora typeOne sample observed has a hard thick gritty fabric with frequent inclusions protruding through the surfaces. The inner core is brown (7.5YR 5/2) sandwiched between a reddish yellow fabric (5YR 6/6). The surface is reddish yellow (7.5YR 7/6). |

Visual characteristicsA fairly hard, rough sandy fabric containing small white inclusions of limestone, buff (7.5YR 7/4) colour throughout. |
PetrologyWe have examined one sample which shows frequent inclusions of limestone and quartz, with a few grains of pyroxene and flecks of mica. The pyroxene is significant and could suggest an origin not far removed from an outcrop of basic igneous rocks. Basalt outcrops occur in a long strip inland along the length of the Algarve (Peacock & Williams, 1986: Class 22). |
Almagro 51 fabric |
Visual characteristicsThe examples seen by us are in a hard, rough sandy fabric, light reddish-brown (2.5YR 6/4) in colour. Keay (1984) recognizes four fabric varieties. |
PetrologyThin sectioning of the examples seen by us show frequent quartz grains, flecks of muscovite mica, some potash feldspar, limestone, fossils and metamorphic rock (Peacock & Williams, 1986: Class 23). |
