The type is frequently referred to as Throlam ware.
Our samples are medium grey (5/0, Corder’s ‘lead’ grey), often brownish (eg 10YR 7/2–6/2), and can be quite soft. The fracture is irregular and the feel rough/powdery. Typical forms are flanged bowls (the so-called ‘truncated-conical’ form), large deep bowls, large handled jars and narrow-mouth jars, sometimes with a lightly burnished external surface. Subjectively, the fabric can be described as hard and ‘crisp’, making a distinctive ‘ping’ when hit with a thumbnail (J Evans, pers comm).
The inclusions in this fabric are well-sorted (0.1–0.2mm), dominated by abundant quartz in a matrix of sparse fine silver mica. Black, grey and red-brown iron-rich grains can also be identified, although they are sparse. The later (4th century) fabric is more distinctive and tends to have fewer quartz inclusions (J Evans, pers comm).
This is a well-sorted fabric containing abundant quartz, frequently 0.2mm with grains to c 1.5mm, set in a silty matrix. Muscovite mica is extremely rare. Other inclusions are sparse, but feldspar, polycrystalline quartz, coarse flint-like material, and rare argillaceous siltstone occur. Some small opaques (<0.1mm) can be seen, but the darkness of the clay inhibits identification.
Kilns are known at a number of sites on Holme-on-Spalding Moor, including Hasholme, Bursea and Throlam (Corder 1932; Halkon 1983; Hicks & Wilson 1975).
