Portable Clay Stove Construction
Pictures and Instructions from IFSP, Malawi
1: pound the clay until it is soft
2: remove all stones and plant residues
3: make a flat base - the size of your pot
4: start building up the body of the stove
5: the height should be 20 cm when moulding
6: join the 'sausages' and don't leave gaps
7: smoothen the walls outside and inside
8: flatten the edge with an inclination inside
9: fit three pot rests in equal distance
10: potrest height should be 1.5 cm (one finger)
11: draw the door 12 cm high between two potrests and mark the position for the handles
12: make holes in the wall to fit the handles right through the wall, so they don't break off
13: finished handle
14: cut the door after one day and fit a knob
15: the stove is finished and needs to dry slowly for 2 - 3 weeks covered in a cloth or bag
16: the stove can be used like it is or get fired after it is dried. See the how-to guide on construction of a kiln for firing clay stoves. Firing increases longevity.
All pictures were taken by Christa Roth, then Advisor for Food Processing and Biomass Energy Conservation to the Integrated Food Security Programme (IFSP), Mulanje, Malawi. The IFSP programme was commissioned by the German Ministry of Economic Co-operation and Development, later by the European Union and implemented by the German Technical Co-operation (GTZ). IFSP started 1996 and was operating in 185 villages in Mulanje District in south-eastern Malawi until 2004. Since June 1999, it had been co-operating with ProBEC (Programme for Biomass Energy Conservation in Southern Africa) and was transformed into a regional training centre for ProBEC in 2005, taking the experiences from Mulanje to the entire region, including the neighbouring countries.
More than 150 stove producer groups were trained in Malawi alone. The stove design was originally advised by expertise from ITDG (now Practical Action) in Kisumu, Kenya. The training of producers and awareness campaigns were carried out mostly by various implementation partners countrywide.
