Preparation materials: loose coal, loess, appropriate amount of water

Preparation method:

1. Mix loose coal and loess in a ratio of 1:1 , then water them at a ratio of 1.8-2 times (less water means failure, more water means failure), and mix them evenly.

2. Grasp the briquette machine with your hands and crush the reconciled coal hard.

3. Repeat the rolling motion six or seven times.

4. Then pick up the briquette making machine and find a clean open space.

5. The briquette machine cannot be placed on the ground. It must be three centimeters away from the ground. Use the thumbs of both hands to lightly press the switch on the briquette machine, and a handmade briquette will come out.

6. After beating the briquettes, dry them in the sun until the color of the briquettes becomes a little white. If the weather is good, it will take two days to dry in the sun.
