[Stoves] Clay as a binder in biomass pellets

[Paul S. Anderson]

Nikolaus,

Would you please be so kind as to make the posting.  I am not 
subscribed to the
TerraPreta listserv (but know that I should be, but I really must complete my
TLUD stoves work first if I am to be of use to that listserv.)

Note:  The suggested REPEATED use of the clay implies that the briquettes are
burned all the way to ash, not just to the charcoal stage and then placed into
the soil.

To use clay with biomass to make briquettes for TLUD usage (consumed 
only to the
charcoal stage) means that new clay is needed with each batch of briquettes.
