[Stoves] Geopolymer, ceramic like cookstoves

Hi Richard et al, yes we have developed highly insulative, hardened fire 
bricks for cookstoves at the University of KwaZulu-Natal with the 
assistance of the late Prof Juliete Armstrong.  The recipe and 
associated royalties are now with Prof Mark Laing (Planet Earth 
Biopower) our strategic partner in the Vuthisa Biochar Initiative.  
Actually I think Crispin has the best in-depth knowledge on this 
subject, but I know Rok has done great work too.

Regards

Kobus

Kobus Venter and Rok Oblak and probably a hundred others have experimented with the same thing in years past but you have managed to nail it down:   Clever stuff and all the best to you…
