The stove is made of rammed earth, includes a chimney for ventilation, and sealed comals.. In the village of Majamout we found that the front comal is only used for tortillas and that the comal is taken off and a grate placed on when cooking in pots. This increases the amount of smoke in the house depending on the draft of the chimney, but increases the amount of heat directly hitting the pots and thus reduces fuel use. Also, canals redirect the heat from the combustion chamber to the back comals. We found in the village of Majamout the secondary burners are not used to cook on, but rather used as warmers. With our heat distribution tests this makes sense given that even after an hour these back comals are 6 times cooler then the front comal.","Page image":"File:100 1290.JPG","Page language":"en","Page license":"CC-BY-SA-3.0","Page location":"Mexico","Page title":"Lorena Cookstove","Page views":"967","Page year":"Friday, 01-Jan-10 00:00:00 UTC","Modification date":"Friday, 28-Nov-25 12:45:03 UTC"}
