HGHCW1 - Haughley Coarseware 1

Moderate to common fine to medium quartz and rare coarse to very coarse quartz or flint. Sparse silver mica can be present mainly on surfaces. Fabric may also contain very small amounts of chalk or white calcareous inclusions, rare red iron oxide and rare to sparse black shiny iron mineral. (Thompson 2018)

TS sample description (Patrick Quinn): Abundant well-packed, sub-angular to sub-rounded silt-sized inclusions of quartz with less common muscovite mica, plagioclase and opaques. Relatively sparse fine and medium sand-sized more rounded inclusions of quartz, polycrystalline quartz and chert also occur. Non-calcareous reduction-fired clay matrix that may be vitrified. Contains several clay-rich and inclusion-poor pellets and plastic streaks that could be suggestive of mixing. Possible silt-rich areas also exist that may indicate the other component. Frequent meso-elongate drying voids.

Example from the kiln site.

HGHCW2 - Haughley Coarseware 2

Fine silty matrix with dispersed medium to coarse or very coarse quartz and flint. The individual grains are visible on the outer surface. Occasional iron mineral or other inclusions. Little or no mica present. (Thompson 2018)

TS sample description (Patrick Quinn): Poorly sorted medium sand to silt-sized inclusions of quartz with less common polycrystalline quartz, chert and ferruginous inclusions, and silt-sized mica. Inclusions are unevenly distributed due to clay mixing. Non-vitrified, non-calcareous oxidised clay matrix. Clear evidence for clay mixing in the form of plastic clay porphyroclasts of clay-rich and inclusion-rich material, plus streaking. Occasional elongate voids and one large vugh.
