An outdoor fire will likely be the easiest for making activated charcoal, but you can also do this in your home fireplace. The fire should be hot enough to cause wood pieces to burn. Take safety precautions when lighting a fire and always keep a fire extinguisher nearby. If hardwood is not available, you can substitute almost any dense, fibrous plant material, like coconut shells. Insert your hardwood pieces or plant material into a metal pot, then cover it with a lid.  The lid of your pot should have a vent hole, though airflow to the inside of the pot should be limited throughout this process. You could use a camp cookware kettle so the air can escape through the spout, for instance. The material you burn should be as dry as possible before you put it in the pot. Set the lidded pot on the fire. As the material cooks, you should see smoke and gas escape from vent hole in the lid. Doing this will burn away everything from the material except the carbon (charcoal) in it. When no more smoke or gas seems to be coming from your pot, it’s likely finished cooking. The charcoal now in your pot will stay hot for a while. Give it plenty of time to cool down. When it’s cool to the touch, transfer the carbon to a clean container and rinse it with cool water to remove ash and any remaining debris, then drain the water. Transfer the cleaned charcoal to a mortar and pestle and grind it up into a fine powder. Alternatively, you could put the carbon in a durable plastic bag and crush it up into a fine powder with a tenderizing mallet or a hammer. If you used a plastic bag, transfer the powder to a clean bowl, otherwise you can leave it in the mortar. In about 24 hours, the powder should be dry. Confirm the dryness with your fingers; the powder should be fully dry before you move on.
أضرم  نارًا متوسطة في منطقة آمنة. املأ إناءً معدنيًا بقطع الخشب الصلب الصغيرة. ضع القدر على نار مفتوحة مدة 3 إلى 5 ساعات لصنع الفحم. نظف الفحم بالماء حين يبرد. اطحن الفحم. اترك مسحوق الفحم يجف تمامًا في الهواء.
