THETS - Sudbury Thetford-type ware

Very fine sandy micaceous greyware. Quartz grains mainly clear. Burnt-out organics visible in section.

TS description (Patrick Quinn): Moderately well-packed, angular to sub-rounded silt-sized quartz and iron-stained chert, muscovite mica and rare plagioclase and opaques. Rare rounded sand-sized quartz and polycrystalline quartz. Vitrified, reduction fired non-calcareous clay matrix. Vesicle-shaped voids perhaps from over-firing, plus rare vughs. Less sandy, more silty than Samples 1 an 2. Less well packed than THETI sample.

Example from production waste site in Sudbury.
