Oxidised red fabric; brown (PPL), brown (XP).
Semi-heterogenous matrix, non-calcerous with no to low optical activity.
- ca. 40-60%
Inclusions
Quartz (++; mono+, poly-, cf: r-sr, fine to medium sand, ff: r-sa, very fine to fine sand, bimodal: posibly natural), sedimentary rock detritus (+-; quartz arenite, possible few micacious rock fragments), chert (+-), flint (+-), metamorphic rock detritus (+-; low and high grade from sedimentary parent rock), feldspars (+-; plagioclase), muscovite mica (+; el, cf & ff), glauconite (+; r, ff, redbrown body color), O/Fe (+), clay pellets/semi-plastics (+-; iron-rich), grog (+; sharp to clear boundaries, equant shape, discordant feature, various sizes and compositions: mainly oxidised fabrics, possible reduced grog fragment, few dried clay pellets, iron-rich and poor, various optical activities).
The coarse fraction consists of fine to medium sand, the fine fraction consists of very fine to fine sand. Grains are generally rounded to subangular. Overall the fabric is very poorly to poorly sorted and poorly orientated, close to singlespaced.
- ca. 30-40%
Voids
Many small planar voids and channels, few larger vughs, moderately well aligned, some infill at he edges.
- ca. 10-20%
Diagnostic features
The fabric is characterized by a semi-heterogeneous oxidised matrix with no to low optical activity, moderate (high) porosity and intentional grog temper. Dominant quartz inclusions with frequent grog, muscovite mica, glauconite and opaques/iron oxides, common sedimentary and metamorphic rock detritus, chert, flint, feldspars and clay pellets/semi-plastics. Overall very poorly sorted fabric.
Additional information
Grog temper is a mixture of various compositions and textures. This indicates that the tempering material was not carefully selected, but rather a supply (of waste?) of various ceramics was crushed up and mixed into the same tempering raw material. Sand fraction might also be added, but some overlap in grain sizes and unclear distinction in minerals indicates rather a natural slight bimodality.
