Some lovely stove footage.  But can someone please explain what I am 
missing by not quenching char with water and subsequently drying it, over 
just shoving it in an old biscuit tin and putting the lid on, then 
riddling (seiving) out the ash when the tin is no longer warm, and the 
char cold, which IME usually takes little more than 10 mins should I even 
want to make it available that fast?  The ash restores valuable minerals 
to the soil as well as the benefits of the char fines that fall through 
the fine mesh I use, all ending up on our vegetable patch.
