Installation of the grate Place a circle of standing bricks (24 cm high) along the bottom of the inner wall of the iron bucket, and then place the steel bar of the appropriate length on the bricks at intervals of 1 cm, and fix them with mud or cement.
Place two layers of standing bricks around the iron bucket above the grate, and then use mud to wipe the hearth on the brick surface. The hearth should be slightly shaped like a pot bottom to facilitate the concentration of fuel in the middle of the nozzle.
The inner diameter of the hearth is about 35 cm. . (Be sure to wait for the furnace to dry before you can ignite it)
