Brick Making in India

The Bull Trench Kiln (BTK), which is very popular in the Indian sub continent, is an arch-less modification of the Hoffman’s kiln. It is circular or elliptical in shape. Bricks to be fired are arranged in a trench and tall movable metal chimneys are placed on the brick setting. They are moved as the firing progresses.
