The Kiln Decides the Colour
Six potter families in Bogura, one clay bank, and an eighteen-hour wood firing that no two pieces come out of the same.
The clay comes out of a bank the families have dug for four generations. It is alluvial, grey when wet, and full enough of fine silt that it throws almost without grog. Nothing is added to it but water and time.
Everything is thrown on a foot-driven wheel. There is no electric wheel in the compound and no interest in one — the foot wheel decelerates naturally as the potter's leg tires, which turns out to suit the clay's plasticity better than a motor holding a constant speed.
Firing is where the character arrives. An updraft wood kiln runs for about eighteen hours and reaches somewhere between 900 and 1000°C, but not evenly. Pieces near the flue come out darker, almost aubergine. Pieces at the back stay the orange most people expect from terracotta. Buyers occasionally write to ask whether they were sent the wrong item. They were not; they were sent a record of where their pot stood.
Nothing is glazed. Unglazed clay is porous, which is the entire functional point: a kolshi sweats and cools the water inside it by several degrees, a planter lets roots breathe, a soap dish wicks water away from the bar. Glaze would make all three worse and only the photographs better.
