The method goes back to ancient Egypt and Greece, and was probably the first form of masonry oven. It is possible to get some of
Ceramic houses a clay structure water resistant. Ceramic kilns often outlive the earth constructed buildings they are close to. The materials for this type of building are accessible to those with very basic resources. Fuel for firing is the most expensive investment. The hardened membrane of a ceramic dome improves resistance to earthquakes. The structure of a ceramic house improves passive heat use through thermal mass. Added benefits involving the firing process include the opportunity to produce other ceramic goods for use or income, and, when firing an existing house, pest evacuation will occur naturally. Experimental fired earth housing has also been
