Sample: SLO6

Monument: Slocene settlement
Location: Tukums Municipality, Lapmežciems parish, shore of River Slocene
Chronology: Middle Neolithic (3900-3000 BC)
Kind: Pottery sherd

Publication: Haferberga (Visocka) et al. 2024
Description:
* Clay paste – medium coarse with various sized sand and silt, few ferric concretions and grains of mica (biotite) were distinguished as well (largest grain – 0,9 mm).
* Pores – some are uneven, asymmetric and elongated, others are small and round – oval shaped.
* Temper: grog + mussel shells + crushed granite + unidentifiable organic matter:
- Largest size of the grog grain – 3,7 mm, max. avg. – 0,8 mm;
- Largest size of the pore from mussel shells – 3,2 mm, max. avg. – 1,7 mm;
- Largest size of the crushed granite grain – 1 mm, max. avg. – 0,54 mm;
- Largest oval pore – 1 mm, max. avg. – 0,39 mm;
- Amount of the temper in the clay paste – 20,5%.
* Description of the largest grog grain – fine with few fine sand and silt grains, tempered with crushed granite (size – 0,5 mm) and mussel shells (2,1 mm). Oval small pores were identified as well (largest – 0,2 mm). Total volume of the temper – 9%.
! Values are recalculated using more precise methodology and differs from ones in the publication.
