A mixture of sand, clay, and water is poured into a mold and left in the sun to dry. When dried, it is exceptionally strong and heat-resistant. Adobe does not let much heat through to the inside of the structure, thus providing excellent insulation during the summer to reduce energy costs.
[1] Fire-retardant gels can also be slurries that are composed of a combination of water, starch, and clay. [2] Used as fire retardants, they can be used for structure protection and in direct-attack applications against wildfires. [3] [4] Fire-retardant gels are short-term fire suppressants typically applied with ground equipment. [5]
Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. The United States Environmental Protection Agency defines fire clay very generally as a "mineral aggregate composed of hydrous silicates of aluminium (Al 2 O 3 ·2SiO 2 ·2H 2 O) with or without free silica."
Fire-retardant materials are designed to burn slowly.. Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat.
Clay coating is a nontoxic additive which often meets these requirements. Traditional clay-impregnated light straw insulation has been used for centuries in the northern climates of Europe. The clay coating gives the insulation a half hour fire rating according to DIN (German) standards.
Paper clay is handmade or commercially available clay to which a small percentage of processed cellulose fiber is added. The fiber increases the tensile strength of the dry clay and enables dry-to-dry and wet-to-dry joins. Commercial paper clays air-dry to a firm, lightweight sculpture, with minimal shrinking during the drying process. [4]
