Rocket Stove

“The Rocket Stove is a variety of wood-burning cooking stove. It is easy to construct, with low-cost materials. These are low-mass stoves designed to burn small pieces of wood very efficiently. Cooking is done on top of a short insulated chimney. The stoves are typically constructed out of trash: tin cans, old stovepipes, etc. A skirt around the pot will help hold heat in, increasing the efficiency.

Rocket Stoves use branches, twigs, small wood scraps, or just about any small combustible material. The pieces of wood or other material burn at their tips, increasing combustion efficiency, creating a very hot fire, and eliminating smoke. The low-mass stove body and insulated chimney ensure that the heat goes into the cooking pot, not into the stove. Rocket stoves used in conjunction with hayboxes can save enormous amounts of fuel, cooking complete meals while using very few resources.” You can read the rest of the descriptive article here.

In the following videos, Chris Towerton, shows us how to construct a rocket stove cob oven. He uses clay, a steel pipe and straw.:

Chris’ inspiration video was by Jon and Flip who have built these ovens for firing pottery and for baking/cooking food as part of their relief work in Haiti.

Using ‘Natural’ Clay to Make Pottery

These videos were eye-openers for me, because I hadn’t really thought of clay in the soil as anything other than a nuisance and certainly hadn’t thought of using it for anything.

Here we learn how to find and clean clay found in a river bank. There seem to be two methods of cleaning ‘natural’ clay. One is to dry the clay and then powder it and put it through a sifter screen, the other is to put a slurry of wet clay through a sieve. I haven’t tried either, though the wet method looks easier.

“Is mixing your clay economical. I hear arguments on both sides. But I think it’s important that you know how.”

Here wildmudpottery finds clay in a trench dug for a pipeline and uses the second wet method of cleaning the clay.
