Before proceeding to know the meaning of the term clay, we have to undertake
the establishment of its etymological origin. In this case, it must be
determined that it derives from the Latin, exactly, from the word "argilla",
which can be translated as "potter's clay".

from the aggregation of aluminum silicates derived from the
decomposition of various minerals. These silicates are hydrated and, depending
on the presence of impurities, can exhibit different colors.
clay is an aluminosilicate (as it contains aluminum oxide
and silica) from a chemical point of view, and a colloid (a system made
up of at least two phases) from a physical perspective. Each particle that makes
up the clay has a diameter that does not exceed 0.002 millimeters.
And in Prehistory the human being used for
different manufacturing clay utensils. Clay, when it comes into contact with water,
develops its plastic properties and can be easily molded. Once it dries, it
becomes firm. If it is also heated to more than 800º C, the
clay hardens permanently and becomes ceramic.
