Tiles are made in the same manner as bricks, but are thinner and lighter, so require greater care.
These are manufactured from a clay mass with or without admixtures of colouring impurities
by moulding and subsequent burning until baked, up to about 1300 °C. The clay should be
highly plastic with lean admixtures and fusing agents to lower the melting point. These are
moulded in machines of the auger or plunger type and are commonly burned in continues
kilns.

moulded. Their specifications are given in Table 2.5. Hand moulded tile is marked with symbol
H and the machine moulded tile with symbol M.
