⚒️Building a natural draft furnace requires careful construction of the furnace walls using mud and water.
🔥Dry weather is ideal for building the furnace, as the mud needs time to dry and harden.
🔗Sealing cracks in the furnace walls is crucial to maintain the draft and prevent air leakage.
🌬️Four opposing air entries are added to the furnace to provide a strong draft.
🔨Tuyeres, or air pipes, are made from clay and installed in the furnace walls to allow airflow.
