[Stoves] Upgrading charcoal by washing it

[Dan Dimiduk]

Dr. Karve,  we have all seen this. Anytime charcoal is left after an outside fire, the rain washes it.  I would suspect the more soluble compounds would wash quite easy. An ebb and flow wash would be most effective. Wash water should have the lowest salt content possible.  Some.charcoals have a more open porosity than others. Smaller particles would wash more completely. As far as silica, I doubt if the compounds would dissolve enough to remove all of it. Some plants are much lower in silica than others as you know. As usual, the best way to know is to try washing the charcoal you have with distilled water and dry it before and after. Then weigh it. Then dry out the water and test the residue. Or just test the water. Then you know exactly. Dan Dimiduk
