Aimed at those working on stove projects or manufacture of ceramic stoves, this books offers clear explanations of some of the causes of the problems encountered while the stove is in use and gives straightforward methods of avoiding them. The findings of a clay-testing programme carried out with a number of different Asian and African clays are outlined and results show a strong correlation between the clay/non-clay ratio. It describes a method of clay testing, the clay/non clay ratio measurement technique which will reduce the chance of stoves failing through thermally induced stress.
