SIPS - 'Sandy' Ipswich Ware (Group 1)

Frequent fairly well-sorted angular to sub-angular quartz sand, generally less than 0.3mm but with some larger grains, including some polycrystalline. Also flecks of mica, some small pieces of chert in the same size range as sand, a little quartzite, a few small grains of felspar, iron oxides and occasional fragments of ironstone and fine-grained sandstone. Some sherds contain a few well-rounded light brownish pellets of glauconite. Feel slightly rough. (After Blinkhorn 2012)
