[Terrapreta] Char sorption of water.

[Brian Hans]

  Im looking for a bit of help.
   
  Some of you with access to char, could you run a simple experiment and offer some results?
   
  Putting a fixed amount of charcoal in a vessel, add water until it doesnt pour out of the vessel anymore and record that sorption #. 
   
  An example is that I put in 10g of material into a glass and started adding water until it couldnt uptake it anymore. I then poured out the excess water from the glass and recorded the amount of uptake. In this case, I got ~225% weight uptake. 

  Im looking for some others results to compare my material with...
   
  FYI perlite = 200-600%
   
  Thanks for the inputs!
  Brian
