Always wondered where that design came from. Seemed to just turn up in nairobi in the early 80's! I ran across ot again in Bamaco Mali in early 2000, and again in Uganda by 2003
Did you know of a one hugh Allen who developed the pug mill and form for larger scale production of it? 
Seem to have really taken off widely: Congradulations ! 
One desigh issue we always had in using it with briquettes though was the tendency for the ashes to bridge the bottom holes. These were formed by punching trur the clay body from inside, which generated a taper, downward shape to these  holes themselves. As they provide the main air supply to the stove, clogging of them greatly reduced the efficiency of the ordinary (relatively high ash producing) ag residue blend of briquette in use.  I modified the holes vertical profile by reaming them out, from bottom, to create a "taper upward" shape which solved the ash bridging problem on our test case but that was in Lushoto in Tanzania in 2007. Have you ever had issues with ash clogging yourself and if so how did you resolve it ? 
Kind regards, 
Richard Stanley

> I chastised him a bit for getting this part wrong:  he states that I helped design the Kenya Ceramic Jiko, when in fact my collaboration started just after the stove was basically designed.  What I helped with was dissemination of the construction skills to artisans.   There was one excellent improvement/simplification made to the ceramic part of the design after I was on the scene, but I did not come up with that.  (I wished I had!)    In 1983, I had advocated for making an illustrated construction manual rather than just an illustrated report to USAID, the funding agency.  I intentionally made drawings that could be photocopied several generations without losing the vital information, and could be read by illiterate artisans, giving them all the information they'd need.   When I visited Max Kinyanjui 23 years later, he told me that those drawings made it possible for him to take the design and construction process all over Kenya and to at least 4 other countries in Africa.   It was one of the most satisfying moments of my life.   But I take no credit for designing or creating the stove.   Just want to set the record straight here.  : 0 )
