Where does clay come from? Clay is a soft, loose, earthy material containing particles with a grain size of less than 4 micrometres (μm). It forms as a result of the weathering and erosion of rocks containing the mineral group feldspar (known as the ''mother of clay'') over vast spans of time.
Clay shrinks both in drying and in firing. Different clay bodies shrink at different rates which can be as little as 4%, or as much as 15% for some clay bodies. Even one percentage point can make a difference in the final product depending on your need for precision.
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 vitrification point below 1100°C (2000°F).
Refractory materials. Refractory materials must be chemically and physically stable at high temperatures. Depending on the operating environment, they must be resistant to thermal shock, be chemically inert, and/or have specific ranges of thermal conductivity and of the coefficient of thermal expansion.. The oxides of aluminium (), silicon and magnesium are the most important materials .
Crush the wet mud between your fingers to as small a size as possible, breaking up all the clumps. Once your mixture is as lumpfree as possible, allow the material to hydrate for several hours. Stir the mixture thoroughly, then allow it to settle for a few minutes. Clay is lighter, and floats above the heavier sediment.
