The Vertical Shaft Brick Kiln. The vertical shaft brick kiln (VSBK) is classed as a continuous updraft kiln and represents a comparatively new and unique method of firing bricks. It was developed in China in the late 1960s during the cultural revolution, when there was a large demand for bricks in the rural areas of China.

In the single wider shaft kiln, each batch of bricks is made up of four layers making a total of 320 bricks, and the shaft holds twelve batches to give a firing capacity of 3840 bricks every 12 hrs. The bottom layer of bricks in each batch, which is the first loaded, consists of 68 bricks arranged in 7 rows to provide six open channels running across the firing shaft.
