1, about 6cm near the bottom of the tile, made some holes with glass perforated bricks, and then put on stainless steel silk thread, thus separating the bottom, which is convenient for ventilation, similar to a coal stove.

2. Then enclose a small bucket with a small stainless steel wire mesh and erect it on the stainless steel wire mesh at the bottom. Then fill cement mortar around the barrel and the inner circumference of the cylinder (cement will crack when it meets high temperature, so there is no other material at hand). After drying, this part is where the charcoal fire is put.

3. Finally, punch a hole in the space above the charcoal fire, and then do not allow the thread to pass through the center of the cylinder when threading, so that the charcoal will not be blocked when it is put in.

4. Finally, take the milk powder can out and cover it, and make maximum use of the hot air that comes out.
