Observation

A large number of candidates attempted this question and performed fairly. Though, few of the candidates misinterpreted properties for function of clay. They were expected to respond to the question thus:
(a) -           It is malleable/workable when wet;
     -           plastic in nature when wet;
     -           less porous;
     -           contains impurities (foreign particles);
     -           it has colour;
     -           it has mineral constituents;
     -           becomes hard when fired;
     -           can dissolve in water;
     -           contains fine particles.
                                                                      
(b)       Dry method

-           Collect dry clay;
-           break the large lumps of clay into small pieces;
-           remove unwanted materials;
-           pound into powder;
-           sieve to remove the remaining impurities;
-           mix with enough water to make it plastic;
-           knead on a surface to remove air bubbles to obtain the right consistency;
-           clay is ready for use or storage
