[Stoves] ***SPAM*** Sawdust, rice husks, coffee husks mixed with clay to make bricks with insulation

[Joshua Guinto]

Hello Kevin

I had a lot of experience with saw dust, rice husk and carbonized rice husk
with clay to make insulating bricks. It is the bricks I used for our
project with Ron Larson. My best mix is clay and carbonized rice husk
(CRH)  in a 1:3 ratio and kneaded very well.Unlike saw dust and raw rice
husk, the CRH breaks down every time the clay is kneaded thus producing
micropores each time. Having these pores smaller helps in the integrity of
the bricks while improving the insulating property of the brick. Will tell
you more in the following days. Too busy today for a series of big
meetings.
