YARN - Yarmouth-type ware non-calcareous

Similar to YAR but with little or no calcareous inclusions. See Mellor 1976 Fullers Hill, Great Yarmouth, Fabric 3.

TS sample description (Patrick Quinn): Sub-rounded medium sand sized inclusions of quartz and rarer polycrystalline quartz, chert and degraded calcareous inclusions. The latter are composed of micritic calcite with some iron staining and pores from their degradation. It is not clear whether they were shell. Sand sized opaque inclusions of various types occur, including rounded opaques without clasts and more angular quartz silt containing features. Opaques occur in the fine inclusions alongside, quartz, chert, rare mica and glauconite. Non-vitrified non-calcareous clay matrix that is oxidised on one edge. Meso-elongate voids and ring voids around inclusions contain secondary calcite infilling, perhaps from the degradation of the primary calcite. Petrographic composition does not fit the definition of ‘non-calcareous’. (NB - this sherd is from Ipswich Stoke Quay and was supplied as a sample of YARN, but it is more likely to be YAR).
