High quality locally sourced and foreign clays are mixed and kneaded together to obtain the desired elasticity before being crushed and prepared. The extruder then compresses the clay through pressure and suction into a long rectangular shape and the desired brick module is cut using a die. Once shaped, the bricks are fully or partially coated with an engobe comprised of a liquid clay with the same capillarity of the clay body. Additional ingredients like metal-oxides and colour-pigments, balanced to create the highly prized semi-glazed finish, are also added. The wet bricks are dried for 4 days, then fired in an automated tunnel kiln reaching temperatures of 1100°c.
