    OverviewFormationGroupingIdentificationHistorical and modern usesSee alsoExternal links

    Clay is a finely-grained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO2), metal oxides (Al2O3,MgO etc.) and organic matter. Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure. Clays are plastic due to particle size and geometry as well as water content, and become hard, brittle and non–plastic upon drying or firing. Depending on the soil's contentin which it is found, clay can

  • Clay Brick an overview ScienceDirect Topics

    Clay bricks are produced by the drying and firing of clay or shale raw material, forming a sintered porous structure. Similarly, the drying and sintering of pelletised clay or shale can produce a usable aggregate, but more especially if the raw material is capable of being ‘bloated’. They are uniform in size, have a pleasant surface and

    clay or claylike material that typically is high in magnesia and has specialized decolorizing and purifying properties. Fuller’s earth, which is very similar to bentonite, is used mainly as absorbents of pet waste, oil, and grease. Common clay is defined as a plastic clay or claylike material with a vit-rification point below 1100°C (2000°F).

  • Clay Shrinkage During Drying and Firing Preventing Defects

    For a example, if clay shrinks 5% during drying, a piece of clay that is 5" long, will shrink 1/4" and a piece that is 20" long, will shrink 1" during the drying. This is why it is beneficial to know that the larger the piece is, the more important it becomes to let it dry evenly (slow drying will yield even drying).
