Making a sawdust stove involves following a few steps. Firstly, gather an empty metal can with a lid and remove any labels or coatings from its surface. Create airflow holes in the bottom section of the can using a nail or drill. Fill the can with sawdust, ensuring it is densely packed for optimal heat retention. Place the lid on top securely. To ignite the stove, open the lid slightly and use a lighter or match to light the sawdust from one of the airflow holes. Once lit, close the lid and allow the flames to stabilize before placing a pot or pan on top for cooking.
