Ron, daniel et al. Apologies for my atrocious spelling. Here is what I was trying to say: Ron, Often greater squeezing pressure (to achieve greater density) is NOT the solution. It is most often about blending the right amount of fibrus material and combustible infiller. Its about attaining the right combination of fibers that are conditioned to flex plastically with an infilling material that is dense yet relatively porous. No amount of force will create a good briquette using the wet process becsue increased pressure results in shearing of the fibers and vaporising the water in the slurry, creating a crude form of steam cannon. I do not know what blend Approvecho uses as we lost contact with them after they visited here to gather what we were doing, but I would say that it is very likely that if you found paper blends there. Relatively dense briquettes can be achieved with paper-based blends by hand but paper is far from the ideal in terms of good hot combustion… Thanks for your patience, Richard Stanley =====
