| Abstract |
| Clay is a product of decomposition of rocks rich in aluminosilicate
minerals. The decomposition may be brought about
by the superficial weathering due to the atmospheric agencies or
by the action of hot vapours or fluids emanating from underground
sources. Clays originated from weathering are hardly deepseated,
whereas those due to the action of underground agencies
have revealed better material at depths. Whatever be the origin,.
a clay must possess that characteristic property called "plasticity'~
which makes it so useful. Clay in finely divided state, either
natural or produced by grinding, can, therefore, be ea:.ily moulded
into any shape which it retains on drying. |
