Clay is a type of fine-grained natural soil material containing clay minerals [1] (hydrous aluminium phyllosilicates, e.g. kaolinite, Al 2 Si 2 O 5 4). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide .
These small blocks of wood can be put together easily to make a structure that, like stone, has insulation as well as thermal mass. Cordwood provides the rustic look of log cabins without the use of tons of lumber. An entire building can be constructed with just cordwood, or stones can be used to fill in the walls.

Cement bonded composites are made of hydrated cement paste that binds wood, particles, or fibers to make pre-cast building components. Various fiberous materials, including paper, fiberglass, and carbon-fiber have been used as binders. Wood and natural fibers are composed of various soluble organic compounds like carbohydrates, glycosides and ...
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al 2 Si 2 O 5 4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water [1] and have been important to life, and many theories of abiogenesis ...
Like the tabun, it too was made like unto a large, bottomless eathenware pot, turned upside down and fixed permanently onto the ground by plastering it with clay, [50] [51] [52] usually in a family's courtyard where there was a baking hut. [53] Tabun oven with lid, from Palestine (1935) These smaller pot-shaped ovens are made of yellow pottery ...
A study published this month describes the way in which a team has been able to make a piece of wood almost completely transparent. Researchers develop see-through wood that looks just like glass ...
In local brickyards, they were called "clay-dogs" either because of their animal-like forms or the concretions were nuisances in molding bricks. [ 81 ] [ 82 ] [ 83 ] Similar disc-shaped calcium carbonate concretions have also been found in the Harricana River valley in the Abitibi-Témiscamingue administrative region of Quebec , and in ...
Wattle and daub is a composite building method used for making walls and buildings, in which a woven lattice of wooden strips called "wattle" is "daubed" with a sticky material usually made of some combination of wet soil, clay, sand, and straw. Wattle and daub has been used for at least 6,000 years and is still an important construction method ...
