if i think back to how to make 'char cloth' out of cotton,
- you put the cotton in a small tin that has a small hole in the lid,
- place the tin over a flame or fire until a smoke starts to come out of the the hole
- when the smoke stops coming out of the hole, remove the tin from the fire.
- What is left in the tin, is 'char cloth'
Question: if I wanted to make char from wood, wouldn't I do something like place wood shavings into a tin, then repeat the same process?
Next Question: If so, soaking the shavings in calcium cloride prior to placing it in the tin, makes it 'activated'?
Is it this simple or have I missed something?
