The Silent Stratigraphy
OCP, BRW, PGW, NBPW & The Chronology of Clay
REALM 45 — ANCIENT POTTERY
MICRO-REALM 01
Neolithic Hand-made
- Earliest pottery, hand-formed before the wheel.
- Coarse fabric, often bearing cord or thumb impressions.
- Found at sites like Mehrgarh and Burzahom.
MICRO-REALM 02
Harappan Ware
- Wheel-turned, mass-produced red ware.
- Painted with black geometric and natural motifs (Peepal leaf, intersecting circles).
- Standardized shapes indicating central control.
MICRO-REALM 03
Ochre Coloured (OCP)
- Late Harappan/Chalcolithic transition (c. 2000–1500 BCE).
- Highly friable; ochre slip easily rubs off on the fingers.
- Often found in association with 'Copper Hoard' cultures.
MICRO-REALM 04
Black & Red (BRW)
- Widespread Chalcolithic/Megalithic ware.
- Result of "inverted firing": rim/interior trapped in reduction (black), exterior in oxidation (red).
- Common in South Indian Megalithic burials.
MICRO-REALM 05
Painted Grey (PGW)
- Iron Age / Later Vedic period (c. 1200–600 BCE).
- Fine, well-fired grey fabric.
- Painted with black linear and dotted geometric patterns.
MICRO-REALM 06
Northern Black Polished
- Mauryan Era / Second Urbanization (c. 600–200 BCE).
- Deluxe ware; extremely lustrous, almost metallic glossy black surface.
- Requires highly advanced clay preparation and high-temperature firing.
MICRO-REALM 07
Rouletted Ware
- South & East India (Arikamedu), c. 2nd C BCE – 1st C CE.
- Characterized by concentric indented rings on the interior base.
- Indicates strong Indo-Roman maritime trade connections.
MICRO-REALM 08
Burial Urns
- Large, coarse red/black jars.
- Used for secondary burials (bones) in Megalithic culture.
- Found extensively at Adichanallur (Tamil Nadu).
MICRO-REALM 09
Red Polished Sprinklers
- Kushana/Gupta periods (Western India).
- Fine red clay with a bright red slip, highly polished.
- Distinctive "sprinkler" shapes, likely used in Buddhist rituals.
MICRO-REALM 10
Roman Amphorae
- Imported pottery found at Indian coastal sites (Arikamedu, Pattanam).
- Tall, twin-handled vessels with pointed bases.
- Used for transporting wine and olive oil from the Mediterranean.
MICRO-REALM 11
Medieval Glazed Ware
- Introduced widely during the Delhi Sultanate/Mughal periods.
- Glassy, waterproof coating (often blue/green).
- Used for both tableware and architectural tiles.
MICRO-REALM 12
The Kiln
- Oxidation: Oxygen-rich fire turns iron in clay red.
- Reduction: Oxygen-starved fire (smothered with ash/dung) turns clay black/grey.
- Control of airflow defines the pottery era.
