[Stoves] Binders by fiber or glue?

[George Riegg Gambia]

richard

thanks for the note on cardboard - yes, there is so much about and it does
dissolve like a dream.
i imagine you have done trials in abundance - could it be used in limited
quantities? i also wonder if it is burned in a vesto type stove which is
very efficient regarding secondary combustion could that deal with the nasty
additions in an acceptable way? is there any data available somewhere?

cheers
